So, you have decided on the ultimate adventure: a blissful stay on the spice-scented shores of Zanzibar, followed by the thrill of a safari in the legendary parks of Northern Tanzania. It’s the perfect combination. But one crucial question remains: When is the absolute best time to go?
The answer isn't just about sunny skies. It's about aligning your trip with Tanzania's wildlife rhythms to witness nature's most spectacular shows. This month-by-month breakdown will cut through the confusion and help you pinpoint the perfect time to book your safari from Zanzibar.
The Two Seasons: A Quick Overview
First, let's understand Tanzania's primary seasons, as they dictate both the weather on the island and the conditions in the mainland parks:
Dry Season (June - October): This is peak safari season. Skies are clear, days are sunny, and wildlife is easier to spot as animals gather around predictable water sources. It's also the coolest time of year.
Green Season (November - May): Characterized by warmer temperatures and periodic rains. This season offers lush landscapes, excellent birdwatching, and the chance to see newborn animals. It's also less crowded and can be more affordable. The "long rains" typically fall from March to May.
Now, let's dive into the specifics of each month.
A Month-by-Month Safari from Zanzibar Guide
January - March: The Calm & The New Life
Weather: Warm and generally dry, with a chance of short afternoon showers. It's humid but very green.
Wildlife Viewing: Excellent. This is a secret highlight! The grass is short, and visibility is great. February is prime time for spotting predators, and it's calving season for the wildebeest, meaning plenty of action.
Zanzibar Bonus: Ideal beach weather—hot, sunny, and perfect for swimming.
Verdict: A fantastic time for those who want a combination of good beach weather and phenomenal, less-crowded game viewing.
Recommended Safaris: 2-Day Wildlife Safari from Zanzibar, 3-Day Tanzania Safari from Zanzibar, 4-Day Safari from Zanzibar
April - May: The Lush & Quiet Escape
Weather: This is the peak of the "long rains." Expect heavy, prolonged rainfall, especially in April. Humidity is high.
Wildlife Viewing: Challenging but rewarding. The landscape is incredibly lush and beautiful. While animals are more dispersed and some roads may be muddy, the parks are empty, and photography is stunning with dramatic skies.
Zanzibar Bonus: A quiet time on the island. You'll find great deals, but be prepared for rain.
Verdict: The best for budget travelers, photographers seeking moody scenes, and those who don't mind trading perfect weather for total serenity.

June - July: The Beginning of the Great Spectacle
Weather: The rains have ended. Days are pleasant and sunny, while nights and early mornings can be surprisingly chilly.
Wildlife Viewing: Outstanding. The dry season is in full swing. In late July, the world-famous Great Wildebeest Migration typically begins its dramatic crossing from the Serengeti into Kenya's Masai Mara. River crossings are imminent, and predator activity is intense.
Zanzibar Bonus: Perfect beach weather—warm, sunny, and less humid.
Verdict: One of the very best windows to book your safari from Zanzibar for a combination of perfect weather and blockbuster wildlife action.

August - October: Peak Season & Prime Viewing
Weather: The heart of the dry season. Expect flawless, sunny days and incredibly dense wildlife around waterholes and rivers.
Wildlife Viewing: Unbeatable. This is peak season for a reason. The Wildebeest Migration is often in the northern Serengeti, making for thrilling river crossing sightings. General game viewing across all Northern parks (Tarangire, Ngorongoro, Manyara) is at its most reliable.
Zanzibar Bonus: Idyllic beach conditions.
Verdict: The ultimate time for guaranteed incredible wildlife sightings. Be prepared for higher prices and more visitors.

November - December: The Short Rains & Renewal
Weather: "Short rains" arrive—brief, sporadic afternoon showers that clear quickly. The landscape starts to turn green again.
Wildlife Viewing: Very Good. A wonderful shoulder season. The crowds thin out, prices drop, and the newborn animals are a delight to see. It's a great time for birdwatching as migratory species return.
Zanzibar Bonus: The island is lush and beautiful, with plenty of sunshine between rains.
Verdict: An excellent balance of good value, decent weather, and very good game viewing.
