Ngorongoro weather has two personalities. The crater rim, at about 2,300 metres, is cool, often misty and can be close to freezing on winter nights. The crater floor, about 600 metres lower, is mild to warm by mid-morning and often sunny. On a single game drive you can go from a fleece and a hot drink at dawn to a T-shirt and sunglasses by lunch.
This guide explains Ngorongoro’s weather month by month, the difference between the rim and the floor, and how the seasons affect wildlife, crowds and what you pack.
Ngorongoro weather at a glance
Like the rest of northern Tanzania, Ngorongoro has two rainy seasons and two drier periods. Rains are usually heaviest in April and lightest from June to October.
| Months | Season | Rim | Crater floor | Crowds |
|---|---|---|---|---|
| January to February | Short dry spell | Cool nights, some mist | Warm, green | Moderate |
| March to May | Long rains (peak April) | Cold, wet, misty | Mild, lush, muddy in places | Lowest |
| June to August | Cool dry season | Coldest, near freezing some nights | Mild, clear | High |
| September to October | Warm dry season | Cool, dusty | Warm, dry, dusty | High |
| November to December | Short rains | Cool, showers | Warm, turning green | Moderate, busy at festive dates |
Rim vs floor: why the difference matters
The rim is high and catches the clouds that roll in from the east. Mornings there are often wrapped in mist, sometimes so thick that the crater below is invisible until the sun burns through, usually by mid-morning. Night temperatures on the rim can drop to around 0 to 5°C in June to August, and lodges rely on fireplaces, heaters and hot water bottles.
The floor sits in the shelter of the walls. Once the sun is up, it warms quickly, and by late morning it can feel hot in the dry season. Rain on the floor tends to arrive as showers rather than steady drizzle.
The practical lesson: dress in layers. Start your crater day in a warm jacket, then peel down as you descend. Karatu, where many visitors stay, is in between: about 1,500 metres, mild by day and cool at night. Read our Karatu weather guide for more.
Ngorongoro weather month by month
January
Warm days on the floor, cool nights on the rim and occasional showers. The landscape is green and the light is clear. A good month to combine the crater with calving on the nearby Ndutu plains.
February
Similar to January and often one of the warmest months. Calving on the Ndutu plains usually peaks around now, drawing predators.
March
The long rains begin. Expect afternoon storms and more cloud on the rim. The crater is lush and quieter.
April
Usually the wettest month. Heavy showers, misty rims and muddy patches on the crater roads. Fewer vehicles and lower lodge rates make it attractive for flexible travellers.
May
Rains ease through the month. The crater is green and fresh, and crowds are still light. Nights start to cool.
June
The dry season begins. Clear skies, short grass and easy game viewing. Rim nights get cold. Visitor numbers rise.
July
Usually the coldest month on the rim, with crisp, clear days on the floor. One of the busiest months.
August
Dry, clear and busy. Dust builds on the roads. Wear layers for the early start and pack a scarf.
September
Warming up, dry and dusty. Animals gather near water on the floor, especially around the swamps and springs.
October
Warm and dry, sometimes hazy, with the first showers possible late in the month.
November
The short rains arrive, usually as short afternoon storms. The crater turns green quickly and crowds thin out.
December
Warm with passing showers. Busy around Christmas and New Year, quieter in early December.
How the weather affects wildlife and viewing
- Animals stay year round. The crater floor has water in every season, so the big animals do not migrate away. Weather changes comfort and crowds more than sightings.
- Dry season: short grass makes animals easier to spot and photograph. More vehicles at big sightings.
- Wet season: fewer vehicles, dramatic skies and green scenery. Flamingos are often more numerous when Lake Magadi has more water.
- Mist: rim views are often best from late morning into the afternoon, after the cloud lifts.
- Roads: the descent and ascent roads are well maintained, but rain can make some floor tracks muddy in April.
A crater day, hour by hour
The temperature swing on a single crater day surprises most first-time visitors. A typical dry-season day looks like this:
- 5:30 AM, leaving Karatu: cool, around 10 to 14°C. Fleece on.
- 6:30 AM, on the rim: cold and often misty, sometimes near 5°C in July. Jacket zipped, windows mostly closed.
- 8:00 AM, on the crater floor: the sun breaks through; the air warms quickly.
- 11:00 AM: warm, low to mid-20s °C; layers off, hat and sunscreen on.
- 1:00 PM, lunch: sunny and warm; dust picks up in the dry season.
- 2:30 PM, climbing out: cooler air on the rim again, clouds building in the rainy months.
- 3:30 PM, back in Karatu: warm enough for the pool.
Photography and the weather
- Morning mist can make moody photos on the rim; wait for it to lift for the classic crater view.
- Dry-season dust softens light by midday; protect lenses with a cloth or bag.
- Green-season storms bring dramatic skies and clear air after rain.
- Midday light on the floor is harsh; the best light is early morning and on the climb out.
What to pack for Ngorongoro weather
- A warm fleece or down jacket for dawn and evenings on the rim, especially June to August.
- A light waterproof jacket for March to May and November to December.
- Layers: T-shirt, long-sleeved shirt, fleece.
- Hat, sunscreen and sunglasses for the floor.
- A scarf or buff for dust in the dry season.
- Warm clothes for sleeping if you are staying on the rim.
Staying below the rim in Karatu gives you milder nights and a pool you can use after the crater. Our lodge is 20 to 30 minutes from Lodoare Gate; every villa has a wood-burning fireplace for cool evenings. See our villas, or read our complete Ngorongoro Crater guide.
