Lake Manyara National Park stays warm and steady all year, with daytime highs of roughly 25 to 30 degrees Celsius and nights cooling to about 14 to 18 degrees Celsius. The narrow swing means no month is uncomfortably hot or cold for a game drive. The park sits on the floor of the Great Rift Valley in northern Tanzania, a little south of the equator and around 960 metres above sea level, which tempers its climate.
Because the park is so close to the equator, the length of the day barely changes, so the real driver of temperature here is the wet and dry cycle rather than a summer and winter as most travellers picture it. The wetter months feel warmer and more humid, and the dry season brings crisp mornings and mild afternoons. This guide walks through the temperature month by month, points out the warmest and coolest stretches, and explains what the numbers mean for a game drive and for what you pack. If you want the fuller picture on rain and humidity, pair this with the weather guide.
How Temperature Works Near the Equator
Places near the equator do not get the strong seasonal temperature shifts that you find far to the north or south. The sun stays high in the sky all year, so the amount of heat reaching the ground stays fairly constant. What changes at Lake Manyara is cloud cover and moisture. During the rainy months, clouds trap warmth overnight and the air feels muggy. During the dry months, clear skies let heat escape after sunset, which is why dry-season nights can feel surprisingly cold even though the daytime is pleasant.
Altitude matters here too. The park floor sits low, near the lake, while the rift wall to the west climbs steeply to well over 1,500 metres. Air cools as you go up, so the forested escarpment runs cooler and damper than the open plains by the water. A rough rule is that temperature drops around 6 degrees for every 1,000 metres you gain, so a lodge perched on the rim will feel a few degrees fresher than the lakeshore, especially at night. This is worth keeping in mind if your accommodation sits above the valley floor.
Quick read: Daytime highs hold near 30 degrees Celsius from December through March, dip to about 25 degrees in June and July, then climb back toward 29 degrees by the end of the year. Nights are mildest in the wet months and coldest from June to September.
January to March: The Warmest Stretch
These are the hottest months at Lake Manyara. Daytime highs sit right around 30 degrees Celsius, and the air carries more moisture, so it can feel heavier than the number alone suggests. Nights stay mild, generally between 17 and 18 degrees Celsius, which means you rarely need more than a light layer after dark. January and February fall inside the short dry spell that often splits the rains, while March usually marks the start of the long rains, with afternoon build-ups of cloud and the odd downpour.
For game drives, mornings in this period are warm and comfortable from the start, so you do not need to bundle up the way you would later in the year. The trade-off is stronger midday heat and higher humidity, which can push animals into the shade during the hottest hours.
High around 30C, low around 17C. Warm and fairly humid, part of the short dry break.
High around 30C, low around 17C. The warmest month overall, with muggy afternoons.
High around 30C, low around 18C. Still hot, with the long rains often beginning late in the month.
April and May: Warm, Wet and Easing Down
April and May sit in the heart of the long rains. Daytime highs ease back a little, to about 27 degrees Celsius in April and 26 degrees in May, as thicker cloud cover shades the ground. Nights stay soft, near 18 degrees in April and around 16 degrees in May. The air is at its most humid now, and the escarpment forest drips with moisture. Rain tends to arrive as heavy afternoon showers rather than steady all-day drizzle, so mornings can still be bright and warm.
The temperature itself is gentle in these months, but the wet ground and greener bush change the feel of a drive. For a full breakdown of which months are driest and busiest, the best time to visit Lake Manyara page lines the temperature up against rainfall and crowds.
High around 27C, low around 18C. Peak of the long rains, warm and very humid.
High around 26C, low around 16C. Rain easing by month end, air starting to feel fresher.
June and July: The Coolest Months
June and July bring the lowest daytime highs of the year, both averaging about 25 degrees Celsius. These are the coolest months at Lake Manyara, and the change is felt most sharply at night and in the early morning. Nighttime lows drop to around 14 degrees Celsius, and on the coldest nights the thermometer can read closer to 13 degrees, particularly on higher ground near the rift wall. The rains have stopped, skies are clear, and the dry air lets heat radiate away fast once the sun sets.
This is when an early game drive genuinely feels cold. Setting out at first light in an open vehicle, with the wind of movement added on top, you will want a warm layer and something for your hands. By mid-morning the sun takes over and the day settles into a comfortable, dry warmth that many travellers find close to ideal. Rainfall in these months is minimal, so if you want the fine detail on how dry it gets, see the rainfall by month figures.
June and July give you the coldest dawns of the year and some of the most comfortable afternoons, a swing of more than ten degrees between sunrise and midday.
High around 25C, low around 14C. Dry, clear and cool, with chilly early mornings.
High around 25C, low around 14C. The coolest month, with dawn temperatures near 13C on the ridge.
August and September: Cool Mornings, Warming Days
August holds close to July, with highs near 26 degrees Celsius and nights still around 14 degrees. September starts the climb back toward the warmer end of the year, with daytime highs reaching about 28 degrees Celsius while nights stay cool at roughly 14 to 15 degrees. The days grow noticeably warmer through September even though the mornings remain fresh, so the daily temperature range is at its widest in this part of the year.
This stretch is dry and settled, which keeps the dust down before the shorter rains and makes for reliable, comfortable game viewing. You will still want a jacket for the first hour or two of any morning drive, but you can shed it well before the drive ends.
High around 26C, low around 14C. Dry and mild, mornings still cold.
High around 28C, low around 14C to 15C. Warming through the day, cool at dawn.
October to December: Warming Back Up
The last quarter of the year sees the temperature settle back into its warmer pattern. October highs reach about 29 degrees Celsius, and November and December hold near 29 degrees as well. Nights warm through this period, from around 15 degrees in October up to 17 degrees by November and December, as the short rains bring back cloud cover that holds heat overnight.
The short rains usually arrive in November, often as brief afternoon or evening showers that clear quickly. Mornings and nights become milder again, so the sharp dawn chill of the dry season fades. By December the park is back to warm days and gentle nights, closing the yearly cycle much where January picks it up.
High around 29C, low around 15C. Warm and mostly dry, nights beginning to soften.
High around 29C, low around 17C. Short rains often start, milder nights return.
High around 29C, low around 17C. Warm days, mild nights, occasional showers.
What the Temperature Means for a Game Drive
The single most useful thing to know is that the daytime temperature is comfortable in every month. There is no time of year when the heat becomes punishing or the cold shuts things down. What actually shapes your day is the gap between the cold early morning and the warm afternoon, and that gap is largest in the dry months from June to September.
Morning game drives leave before or around sunrise, which is the coldest point of the day. In an open safari vehicle, moving through the air, a dry-season dawn near 14 degrees Celsius feels much colder than that figure sounds. Dressing in layers is the answer. Start with a warm top and a windproof layer, then peel them off as the sun climbs. By late morning you will be in shirtsleeves. Afternoon drives run the opposite way, starting warm and cooling as the light fades, so a light layer for the return leg is worth having on the seat beside you.
Packing note by season: For June through September, bring a fleece or warm jacket, a hat and light gloves for morning drives. For the warmer, wetter months, focus on light breathable clothing, sun protection and a compact rain layer for afternoon showers. A wide-brimmed hat and sunscreen earn their place all year because the equatorial sun is strong whenever the sky is clear.
Wildlife behaviour tracks the heat as well. On hot afternoons in the warmer months, animals seek shade and water, so the cooler dry-season days can give steadier daytime sightings. The mild temperatures across the whole year are part of why Lake Manyara reads as an easy park to visit weatherwise, with no month that the climate rules out.

To sum up the yearly pattern in plain terms, the warmest months are January, February and March, when daytime highs sit at about 30 degrees Celsius and the air is humid. The coolest months are June and July, when highs ease to around 25 degrees and nights fall to about 14 degrees. February tends to record the highest average daily temperature, while July records the lowest, and the difference between the two peaks is only around five degrees at midday.
The nights tell a slightly different story. Nighttime lows are mildest in the wet months, near 17 to 18 degrees from December through April, and coldest in the dry months, near 14 degrees from June through September. So the biggest day-to-night swing happens in the dry season, and the smallest happens in the rains. Once you hold both of those patterns in mind, packing and planning become simple, because you know a warm layer matters most between June and September and a rain layer matters most between November and May.
Frequently Asked Questions
What is the hottest month at Lake Manyara?
February is the warmest month, with daytime highs around 30 degrees Celsius and the highest average daily temperature of the year. January and March are close behind at the same daytime peak, and all three carry more humidity than the dry-season months.
What is the coldest month at Lake Manyara?
July is the coolest month. Daytime highs sit near 25 degrees Celsius and nighttime lows drop to around 14 degrees, and on the coldest dawns on higher ground the reading can slip closer to 13 degrees. June runs a very close second.
Does it ever get cold enough to need warm clothing?
Yes, but only at certain times. From June through September the early mornings and evenings are genuinely chilly, and an open-vehicle dawn drive calls for a warm jacket, a hat and light gloves. The rest of the day stays mild, so those layers come straight back off by mid-morning.
How much does the temperature change between day and night?
The swing is largest in the dry season, when a day near 25 degrees Celsius can fall to about 14 degrees overnight, a gap of more than ten degrees. In the wet season the swing is smaller, often only around ten to twelve degrees, because cloud cover holds the warmth in after dark.
Is the temperature different up on the escarpment compared to the lakeshore?
It is. The rift wall to the west of the park rises well above the valley floor, and air cools with height at roughly 6 degrees per 1,000 metres. Lodges on the rim feel a few degrees fresher than the lakeshore, most noticeably at night, and the forested slopes stay cooler and damper than the open plains by the water.
Does the temperature affect what a safari costs?
Temperature itself does not set the price, but the seasons it belongs to do. The cool, dry months from June to September overlap with peak safari demand, so lodge rates and park-related costs tend to sit at their highest then, often several hundred dollars per person per night at higher-end camps. The warmer, wetter months usually carry lower rates and better availability.
