Best Time for a Mikumi Safari from Zanzibar: Dry Season, Rains & Weather
July to September is the best overall time for a Mikumi safari from Zanzibar, in the middle of the dry season, when rain is rare and the herds stay close to the last waterholes on the Mkata floodplain. This guide compares every month, explains what the rainy season means for the light-aircraft flights, and covers the greener months from November to February for birders.
If your dates are already fixed, use the date checker below to see the season, the likely rain and heat in the park, and any rainy-season flight notice for your day.
Mikumi day safaris from Zanzibar are available year-round, but the rains can change your flight times and make the animals harder to find. The day centres on a game drive of several hours in a 4x4 on the open Mkata floodplain, between morning and afternoon flights. In the dry season, from June to October, wildlife gathers near the remaining water; once the rains return, the herds spread out.
If your dates are flexible, July to September offers the best overall balance. It is the middle of the dry season, with rain on about two days a month at Morogoro, the nearest town with long-term weather records, and average highs of about 28 to 30°C. June is also dry, although one fly-in operator still counts it as rainy season. October is hotter, at about 32°C, and the first showers return.
From November to February the park is green and good for birds, but the vegetation is thicker and the herds are more spread out. March to May is the wettest stretch, with rain on about 18 days in April at Morogoro, and the main fly-in operators warn that flights can change at short notice from April into June.
If you are still choosing dates for Zanzibar, June to September is also among the drier months on the island. Once your dates are fixed, plan the safari early in your stay: the main fly-in operators advise returning to Zanzibar at least two nights before an international flight, in case the weather delays the flights.
If thunderstorms are forecast for Mikumi, ask the operator whether the flight times will change.

- Most useful checks for your date:
- Rain, thunderstorms and heat at Mikumi
- About 2 days with rain in an average July or August at Morogoro, against about 18 in April, so a dry-season game drive is rarely rained on
- About 28°C average high at Morogoro in July, against about 32 to 33°C from November to February, for a game drive of several hours
- April into June the rainy season named in the fly-in operators’ notices, when flights can change at short notice
Which months suit which Mikumi safari
| If you want | Choose | Keep in mind |
|---|---|---|
| The best overall balance | July to September | Cool early mornings, so bring a layer for the pickup |
| A dry month at the start of the season | June | One fly-in operator still lists June in its rainy-season notice |
| Animals near water at the end of the dry season | October | Hotter, at about 32°C, and the first showers return |
| Green scenery and the best birding | November to February | Thicker vegetation, herds more spread out, about 32 to 33°C |
| A trip during the long rains | March to May | The wettest months, and flights can change at short notice |
July is the coolest month of the dry season at Morogoro, with an average high of about 28°C, and August and September are only a little warmer, at about 29 and 30°C. Rain falls on about 2 days in each of those months, and September is the driest of all, at under 2 rainy days. June is just as cool and almost as dry, with about 3 rainy days, but it comes straight after the long rains, and one fly-in operator still puts it inside its rainy-season notice.
October is the last month of the dry season, so the animals are still drawn to the water, but the average high reaches about 32°C at Morogoro and rain returns on about 4 days in the month. From November the park turns green; our guide to Mikumi in November covers the start of the short rains in detail.

What the park looks like through the year
Mikumi is open grassland for much of the drive: the Mkata floodplain, dotted with acacia, with the Uluguru and Udzungwa mountains to the north and west, and hippo pools, rivers and seasonal pans. Elephant, buffalo, zebra, wildebeest, giraffe and hippo live in the park all year, and Tanzania National Parks says lions are frequently seen. What the season changes is where the animals are and how much vegetation stands between you and them.
June to October, the dry season. As the pans and rivers dry, the animals are drawn to the water that is left, and Tanzania National Parks recommends this season for concentrated wildlife. The vegetation is thinner, so the animals are easier to see from the vehicle. The dawn is cool and the days are warm and mostly dry.
November to February, the green season. The rains return and the herds spread out across the plains, so a drive covers more ground between sightings. The grass grows, the park turns green, and the national parks authority describes this season as one of dramatic skies and great birding. Frogs and other amphibians are most active with the rains. Our guide to Mikumi in January and February in detail covers the drier spell between the short and long rains.
March to May, the long rains. This is the wettest part of the year at Morogoro and on Zanzibar. The animals are still there, but the vegetation is at its thickest, and the main fly-in operators warn that flights can change at short notice.
Rain, heat and the flights, month by month
The park has no long-term weather records of its own. The nearest are from Morogoro, about an hour by road east of Mikumi, so its figures show the pattern of the year in the park, not a forecast for the floodplain. Zanzibar is where the flights start and end.
| Month | Morogoro, average high and low | Rainy days at Morogoro | Rain at Morogoro | Rainy days on Zanzibar |
|---|---|---|---|---|
| January | 32°C and 22°C | 6–7 | 100 mm | 5–6 |
| February | 33°C and 22°C | 6 | 78 mm | 3–4 |
| March | 32°C and 22°C | 12 | 142 mm | 11 |
| April | 30°C and 21°C | 18 | 204 mm | 17–18 |
| May | 29°C and 20°C | 11 | 75 mm | 14 |
| June | 28°C and 17°C | 3 | 15 mm | 5 |
| July | 28°C and 16°C | 2 | 10 mm | 4 |
| August | 29°C and 17°C | 2 | 8 mm | 6 |
| September | 30°C and 18°C | 1–2 | 7 mm | 5 |
| October | 32°C and 19°C | 4 | 40 mm | 7 |
| November | 32°C and 21°C | 6 | 53 mm | 14 |
| December | 33°C and 22°C | 7 | 91 mm | 12 |
A rainy day here is one with at least 1 mm of rain, and the rain column is the monthly total, not a daily figure. In the park, the game drive is in a 4x4, and the listings carry raincoats for showers, so light rain changes the drive less than it changes the flights.
The flights are light aircraft between Zanzibar and an airstrip in the park, and the operators reserve the right to change departure times or the carrier for operational, weather or safety reasons. The two most-reviewed fly-in safaris on GetYourGuide both name a rainy season in their notices: one says that between 1 April and 1 June weather or airfield conditions may change the safari, and the other that flights can be subject to last-minute changes from April to June. Neither publishes how often that happens. Both advise returning to Zanzibar at least two nights before an international flight home.
Rain on Zanzibar does not follow the inland pattern exactly. The island has two rainy seasons, a heavier one from March to May, with about 18 rainy days in April, and a second from November to December, with about 12 to 14. Morogoro is drier than the island in November and December, so a wet week on the beach does not always mean a wet day in the park.
The heat is steady through the year. Average highs at Morogoro stay between about 28 and 33°C in every month, and the main difference is the dawn: the average low falls to about 16°C in July, so the pre-dawn hotel pickup feels cool in the dry season and warm from December to March.
Fitting a Mikumi safari into a Zanzibar holiday
If you are still choosing dates for Zanzibar as a whole, the drier months on the island are June to September and January to February, and they line up well with the safari: June to September is dry in both places. January and February are dry and hot on Zanzibar, at about 33°C, while the park is in its green season. March to May is the wettest stretch on the island as well as inland. Our Zanzibar and Mikumi itinerary shows where the safari fits into 7, 10 or 14 nights. If your holiday falls over the festive weeks, our Christmas and New Year safari guide covers which dates work and how early to book.
Once your dates are fixed, book the Mikumi safari early in your stay rather than on your last full day: the main fly-in operators advise at least two nights between the safari and an international flight home.
Which Mikumi safari suits which season
- The fly-in day safari with flights and lunch is the most-reviewed Mikumi trip from Zanzibar, rated 4.7 out of 5 across 3,200 reviews. The flight leaves at about 7:45, the game drive runs from about 8:30 to 14:30 with a bush lunch, and its listing carries the 1 April to 1 June notice. It suits the dry season best; in the rains, book it early in your stay.
- The twin-engine day safari uses a twin-engine plane and caps each vehicle at six, and its listing names April to June as the rainy season when flights can change. The same advice applies.
- The fly-in day safari on Viator is rated 4.95 out of 5 across 417 reviews and also includes flights, park fees and lunch.
- The 3-day safari by ferry and train travels by ferry to Dar es Salaam and on the SGR, Tanzania’s standard-gauge railway, inland instead of flying, so it does not depend on the airstrip, and day two is a full day of game drives. It suits a trip in the long rains.

Check your date
Choose a date to see whether it falls in the main fly-in operators’ rainy-season notice, which season the park is in, and the likely rain and heat at Mikumi. Within about two weeks of the date the card shows the forecast for the park; further ahead it shows long-term averages.
In general, June to October is the dry season in Mikumi. At Morogoro, the nearest town with long-term weather records, rain falls on about 2 days a month from July to September and on about 18 days in April, and average highs run from about 28°C in July to about 32 to 33°C from November to February.
The forecast is from Open-Meteo for the Mkata floodplain in Mikumi National Park, in East Africa Time. Averages are long-term figures for Morogoro from the Tanzania Meteorological Authority. The rainy-season notice is the wording on the two most-reviewed fly-in safari listings. For warnings, check the Tanzania Meteorological Authority.
The fly-in safaris named above can be cancelled free up to 24 hours before the start, so you can book once your dates are fixed and look at the Mikumi forecast before the deadline. If your booking has different terms, check them before you rely on that, and see free cancellation and what happens if weather grounds your flight.
How we know
Sources and limits
Rain and heat. WMO climate normals for 1991 to 2020, submitted by the Tanzania Meteorological Authority and archived by NOAA, for Morogoro (station 63866, 526 m) and Zanzibar (63870). A rainy day counts 1 mm or more. Iringa (63887), the other station near the park, is on the highlands to the south-west at about 1,400 m and was not used.
The seasons in the park. Tanzania National Parks’ own Mikumi pages: the dry season is June to October, for concentrated wildlife; the green season brings dramatic skies and great birding; habitats focus wildlife around water in the dry season and spread herds across the plains when the rains return; more than 400 bird species. Secondary safari guides describe the thinner vegetation of the dry season and the thicker cover of the green season in the same terms.
Flights in the rainy season. The know-before-you-go notes on the two most-reviewed fly-in listings on GetYourGuide, read on 20 October 2026. One says that between 1 April and 1 June weather or airfield conditions may make changes to the safari necessary; the other that flights can be subject to last-minute changes in the rainy season, from April to June. Itinerary times, ratings and cancellation terms are from the same listings and the site’s offers data on the same date.
What these numbers cannot tell you. Morogoro is an hour’s drive from the park, at the foot of the Uluguru Mountains, so its figures show the shape of the year, not the weather on the floodplain on a given day. None of the listings named here publishes how often flights are changed or cancelled, and no monthly visitor count for Mikumi is published, so this page does not rank the months by crowds. A dated search on 20 October 2026 found no current closure of the park.

Frequently asked questions
What is the best month for a Mikumi safari from Zanzibar?
July to September offers the best overall balance. It is the middle of the dry season, when wildlife gathers near the remaining water on the Mkata floodplain; at Morogoro, the nearest town with long-term weather records, rain falls on about 2 days a month and average highs are about 28 to 30°C. June is also dry, although one fly-in operator still counts it as rainy season, and October is hotter, at about 32°C, with the first showers returning.
Can you do a Mikumi day safari in the rainy season?
Yes. The day trips are available year-round, and the park is green and good for birds from November to February. The vegetation is thicker and the herds are more spread out, so the animals take more finding. March to May is the wettest stretch, and the main fly-in operators warn that flights can change at short notice from April into June, so book the safari early in your stay and leave at least two nights before an international flight home.
Do flights to Mikumi get cancelled in the rain?
They can be changed. The main fly-in operators reserve the right to change departure times or the carrier for operational, weather or safety reasons, and the two most-reviewed fly-in safaris on GetYourGuide both warn of changes in the rainy season: one from 1 April to 1 June, the other from April to June. Neither listing publishes a cancellation rate. Both advise returning to Zanzibar at least two nights before an international flight home.
What is the weather like in Mikumi by month?
The park has no long-term weather records of its own, so the nearest guide is Morogoro, about an hour by road to the east. Average highs there run from about 28°C in July to about 32°C from November to February, and average lows from about 16°C in July to about 22°C from December to March. Rain falls on about 2 days a month from July to September, on 6 to 7 days from November to February, and on about 18 days in April.
Is the green season good for birdwatching in Mikumi?
Yes. Tanzania National Parks says the green season brings dramatic skies and great birding, and the park records more than 400 bird species, from lilac-breasted rollers and bee-eaters to eagles, storks and waterbirds. The trade-off is that the vegetation is thicker and the larger animals are more spread out than in the dry season.
How hot is it on a Mikumi game drive?
At Morogoro, the nearest town with long-term weather records, average highs are about 28 to 29°C from May to August and about 32 to 33°C from October to February. The game drive lasts several hours in a 4x4, so bring a hat, sunscreen and water in the hotter months. From June to September the average low is about 16 to 18°C, so a light layer helps on the early hotel pickup.
When should I book a Mikumi safari from Zanzibar?
Book once your dates are fixed, and plan the safari for early in your stay rather than the day before you fly home. The main fly-in safaris on this site offer free cancellation up to 24 hours before the start; if your booking has it, check the Mikumi forecast before the deadline. If your booking has different terms, read them before you rely on that.
