Weather in Mwanza

Get up-to-date information about the weather in Mwanza to better plan your trip. Below are fresh data, forecasts, and visual charts.

Mwanza is distinguished by a remarkably even temperature pattern that remains stable throughout the year. The average air temperature hovers around +23°C, with the thermometer rarely exceeding +26°C during the day, while nights bring pleasant freshness with temperatures around +20°C. This climate is ideal for those seeking comfortable warmth without extreme heat.

When planning a trip, the amount of rainfall becomes a key factor. The most favourable time for walks and excursions is June and July — the driest months, when only 3–4 rainy days are recorded. May can also be classified as a relatively dry period (about 9 days with precipitation), which distinguishes it favourably from subsequent seasons.

During the rest of the year, the likelihood of rain increases significantly. Contrary to common stereotypes about a dry autumn, already in September there are about 18 rainy days here. The peak humidity occurs at the end of the year: in November and December, rains can fall almost daily (up to 26 days per month). High precipitation frequency (from 20 to 23 days) also persists from January to April, so for travel during these months, it is worth taking care of waterproof clothing in advance.

Mwanza, located on the picturesque coast of Lake Victoria, is characterised by a surprisingly stable and comfortable temperature regime throughout the year. Thanks to its proximity to the equator, there is practically no sharp change of seasons here, and fluctuations in average temperature are minimal — from 22.7°C to 23.8°C. February is traditionally considered the warmest month, when daytime maximums reach 26.3°C, however even in the nominally "cool" November and December, the air warms up to a pleasant 25°C, creating ideal conditions for travel.

The concepts of "winter" and "summer" in Mwanza are quite arbitrary. The period from June to August, which corresponds to the calendar winter of the Southern Hemisphere, is characterised by dry and sunny weather. At this time, the nights become slightly fresher, with minimum temperatures around 20°C, while during the day the thermometer confidently stays at the 26°C mark. Daily temperature fluctuations here are quite insignificant and usually amount to only 4–6 degrees, so evenings remain mild and warm, allowing you to enjoy long walks without the need for warm clothing.

The climate of Mwanza is largely determined by its location on the shores of Lake Victoria, which ensures high humidity and regular precipitation throughout most of the year. Analysing the statistics, one can highlight a prolonged rainy season that covers almost the entire calendar, with the exception of a short break in the middle of the year. The wettest months in terms of precipitation frequency are November and December, when it rains almost daily — up to 26 days per month. A high probability of precipitation also persists in October, January, and the spring months (March and April).

If you prefer drier weather for travel, you should aim for the clearly defined dry season. It falls on June and July — these are the driest months of the year. During this period, the amount of precipitation is minimal (about 0–1 mm), and rains happen extremely rarely, just 3–4 days a month. This time is considered the most favourable for hiking and excursions, as the sky remains clear more often.

Precipitation in Mwanza falls exclusively in the form of rain; snow does not occur here. A characteristic feature of the local climate is that even in relatively wet months, the volume of falling water remains moderate, despite the large number of rainy days. This suggests that rains can be frequent, but often short-lived or drizzling, which allows nature to remain green and fresh all year round.

The weather in Mwanza delights with stable warmth all year round, so the basis of your wardrobe will be light items made from natural breathable fabrics, such as cotton or linen. During the day, the temperature stays in a comfortable range from +20°C to +26°C, so T-shirts, shorts, and summer trousers will be most appropriate. However, given the proximity of the vast Lake Victoria, evenings here can be fresh and breezy: be sure to pack a light windbreaker, cardigan, or hoodie in your suitcase to use the principle of layering.

Particular attention should be paid to protection from moisture, as the number of rainy days in the year is high, especially in the period from October to May. Even if the precipitation is not too heavy, it happens frequently, so a compact umbrella or a high-quality raincoat are mandatory companions for a tourist in this region. For walks, comfortable, non-slip shoes that dry quickly are best suited, as tropical weather can be changeable.

Do not forget about protection from the equatorial sun: a head covering, sunglasses, and high SPF cream are necessary even in cloudy weather. Since Mwanza is located by the water, it is wise to bring insect repellents with you. If you plan active walks on the rocky terrain of the city, give preference to sturdy trainers or sandals with good foot support.
