Weather in Banda Aceh

Find out what the weather is like in Banda Aceh right now. Below are the latest data, detailed charts, and a forecast to help you better plan your time.

Banda Aceh welcomes travellers with a classic tropical climate, characterised by heat and high humidity throughout the year. Thanks to its proximity to the equator, there are practically no sharp seasonal temperature fluctuations: average figures remain steady in the range of +26...+27°C. Days are usually hot, and nights bring only slight coolness, so light summer clothing will be appropriate regardless of your travel dates.

Rainfall is an integral part of the weather in this region of Indonesia. Although it can rain at any time of year, the distinct wet season falls at the end of the year, especially November and December, as well as April, when the number of rainy days is at its maximum. A relatively drier and more comfortable period is the middle of the year — June and July, when the probability of precipitation decreases, offering more opportunities for outdoor walks and excursions.

Banda Aceh is distinguished by a surprisingly stable and warm climate, where temperatures remain high throughout the year. Due to its equatorial location, there are virtually no sharp seasonal changes here. The average monthly temperature fluctuates within a very narrow range: from +25.8°C in December to +27.5°C in June. The hottest period can tentatively be called the middle of the year, especially June, when daytime highs reach +29.6°C.

The concepts of "winter" and "summer" in the usual sense are blurred here. Summer months are characterised by stable warmth, often accompanied by high humidity. At the same time, the winter period (from December to February) in Indonesia is nothing like a cold season: the weather remains mild and hot, with average daytime temperatures hovering around +27.5°C... +28.6°C. Even in the "coolest" months, such as December and January, the climate remains comfortable for beach holidays and sightseeing.

Daily temperature fluctuations in the city are also minimal. The difference between the daytime heat and night-time is usually only 3–5 degrees. For example, even on the hottest days, the night temperature rarely drops below +24°C. This means that evenings in Banda Aceh remain very warm and sultry, bringing no significant coolness after sunset, so light summer clothing will be relevant around the clock.

The climate in Banda Aceh is characterised by high humidity and frequent precipitation throughout the year, which is typical for the tropical latitudes of Indonesia. There is no snow here, but warm tropical downpours are a common occurrence. Tourists should be prepared for rain in almost any month, so a light raincoat or umbrella will become indispensable travel companions.

The wettest period traditionally falls at the end of the year. The rainiest month is November: the maximum level of rainfall is recorded at this time, and it can rain for up to 28 days a month. A high probability of precipitation is also observed in April and October, when the number of rainy days exceeds 25. During these periods, downpours can be prolonged and heavy.

The relatively "dry" season is not very pronounced, but a noticeable decrease in rain activity occurs in February, as well as in the middle of summer. In June and July, the number of rainy days decreases to 14–15 per month, and the volume of precipitation becomes minimal. This time can be considered the most favourable for planning excursions and walks around the city.

Since a warm tropical climate prevails in Banda Aceh with air temperatures steadily holding around +26...+28°C throughout the year, the basis of your luggage should be light clothing made from natural fabrics. Cotton, linen, or modern "breathable" synthetic materials will be the best choice. Given the active equatorial sun, it is recommended to prefer loose-fitting items in light colours that cover the shoulders and knees — this will not only save your skin from burns but is also appropriate in terms of local cultural traditions.

Rains in this region are a frequent occurrence, and even in the relatively "dry" months (July-August), the number of days with precipitation remains significant. It is especially important to prepare for wet weather if your trip falls between October and December or in April, when it rains almost daily. Be sure to take a light, compact raincoat or a waterproof windbreaker, as well as a reliable umbrella. Footwear should be comfortable, non-slip, and quick-drying; trekking sandals or light sneakers are ideal.

Do not forget about sun protection and small accessories. A wide-brimmed hat, sunglasses, and cream with a high SPF factor (30 and above) are necessary here all year round. Despite the fact that nights in Banda Aceh are very warm (about +24°C), one light long-sleeved sweater may be useful for trips in transport with strong air conditioning. It is also worth bringing repellents, as high humidity contributes to insect activity.
