Is December a good time to visit Kenya?

This is especially true in safari hotspots like the Maasai Mara, Amboseli, and Tsavo, where animals gather around water sources.

A highlight of visiting Kenya in December is the chance to witness the Great Migration in the Maasai Mara. It’s also a great time to explore Shimba Hills National Reserve near Diani, where you can spot elephants, leopards, and rare sable antelopes in lush forests and rolling hills.

The mild weather is perfect for a stroll or picnic in the Nairobi Arboretum, a green oasis in the city with a mix of indigenous and exotic tree species.

Why December is a good time to visit:

• Warm, mostly dry weather: Short rains may linger, but they’re brief: expect sunny days and clear skies, especially in the mornings.
• Beach-ready coast: Coastal spots like Diani and Watamu are hot and humid, with warm sea temperatures ideal for swimming and snorkeling.
• Lush landscapes: The short rains leave the scenery green and refreshed, especially in highland areas and around Mount Kenya.

What about crowds and costs?

December marks the start of Kenya’s high tourist season, with popular parks like the Maasai Mara and Amboseli drawing large numbers of visitors. It's one of the busiest and most expensive times to visit, with accommodation and safari prices at their peak.

The upside? Excellent game viewing, dry weather, and a chance to catch the Great Migration. Clear skies also mean ideal conditions for wildlife photography and outdoor activities.

But expect crowded safari vehicles, long lines, and limited availability, especially around the vacations. If you’re set on December, book well in advance.

Looking for fewer crowds and better deals? Consider the shoulder months, like January or September. You’ll still get great weather and wildlife sightings, without the peak-season chaos.

Where to go in Kenya in December

December is one of the best times to explore Kenya, with warm, mostly dry weather across much of the country. The short rains are fading, the landscapes are lush, and wildlife is active, perfect conditions for discovering some of the best places to visit in Kenya.

Maasai Mara National Reserve

December brings clear skies and green plains to the Maasai Mara, one of the best parks in Kenya. It’s the tail end of the Great Migration, so you might still catch large herds of wildebeest and zebra alongside the Big Five.

The scenery is vibrant after the rains, and game drives are excellent. Early mornings are best for photography, while evenings offer golden light over the savannah.

Amboseli National Park

Set against the backdrop of Mount Kilimanjaro, Amboseli is a December highlight. Elephants are easy to spot around the marshes, and the clear air means great views of the mountain. Roads are dry enough for smooth safaris, and birdlife peaks this time of year with migratory species arriving.

Diani Beach and the South Coast

If you’re after sun and sea, head to Diani Beach, one of the best beaches in Kenya. Expect hot, humid days and warm ocean water: ideal for swimming, snorkeling, and diving.

Nearby Shimba Hills National Reserve offers a quick escape inland for forest walks and wildlife spotting, including rare sable antelope.

Laikipia Plateau

For a quieter safari, Laikipia is a solid pick. Private conservancies here offer guided walks, night drives, and a chance to see endangered species like black rhinos and Grevy’s zebras. The scenery is green and peaceful after the short rains, and lodges often feel more personal than in the big parks.

What to do in Kenya in December

December offers a solid mix of wildlife, culture, and coast: things to do in Kenya this time of year range from classic safaris to beach days and local festivals. The landscapes are fresh and green after the short rains, and the weather is warm and mostly dry. It’s high season, so some spots will be busy, but for good reason.

Nairobi street food and Christmas markets

Nairobi comes alive in December with festive markets, music events, and street food stalls. You’ll find Christmas fairs popping up in parks and shopping centers, especially in neighborhoods like Karen and Westlands.

It’s a great time to try local favorites like nyama choma, chapati, and mandazi, or pick up handmade crafts and gifts.

Snorkeling and diving at Kisite-Mpunguti Marine Park

Down on the south coast, Kisite-Mpunguti Marine Park offers some of the best snorkeling in Kenya. The waters are clear in December, and you might spot dolphins, turtles, or reef sharks around the coral islands. It's a great add-on if you're already spending time at the beaches.

Traditional dance and cultural festivals

Many towns and communities host cultural events during the vacation season. You’ll find traditional dance performances, music, and storytelling in places like Bomas of Kenya or at local heritage festivals around Lake Victoria and western Kenya.

These events are informal, fun, and often include food stalls and crafts: easy to stumble upon if you're exploring smaller towns.

Family-friendly activities

If you're traveling in Kenya with kids, December is a great time. Wildlife parks like Nairobi National Park or Lake Naivasha offer half-day safaris and boat trips that are manageable for younger travelers.

On the cost, calmer waters in Watamu and Diani are perfect for swimming, sandcastle building, or glass-bottom boat rides. Many lodges and hotels also run kid-friendly activities over the school vacations.
