Weather in Atambua

Are you planning a journey or simply want to stay informed about the meteorological situation? In this section, you will find the latest weather data for the city of Atambua, as well as detailed forecasts and charts to help you prepare for any conditions.

The climate of Atambua can be described as typically tropical, with a distinct division into dry and wet periods. Thanks to its proximity to the equator, a perpetual summer reigns here, and significant temperature fluctuations throughout the year are virtually unobserved. Travellers can expect warm and sunny weather, which is only periodically interrupted by the rainy season characteristic of this region.

Two main seasons are clearly traceable throughout the year. The dry period lasts approximately from May to October: during this time, rainfall is minimal, and the sky remains clear (especially in August, when rain is a great rarity). From November to April, the rainy season sets in, reaching its peak in December and January, when precipitation can occur almost daily. This time is distinguished by high humidity and the vibrancy of tropical greenery.

The temperature regime in Atambua is notable for its enviable stability. Average figures remain at a comfortable level of +25...+27°C all year round. During the day, the air warms up to +28...+30°C, while nights bring a pleasant freshness as the thermometer drops to +22...+24°C. Even in the "coolest" months, such as July, the weather remains warm, making Indonesia an attractive destination regardless of the calendar date.

Atambua is distinguished by a consistently warm climate throughout the year, which is characteristic of the tropical latitudes of Indonesia. There are virtually no sharp temperature spikes here; however, the hottest period occurs at the end of the calendar year. In October and November, the thermometer often strives towards the +30°C mark, and the average temperature in November reaches its annual peak — around +27°C. This is the time when the air warms up to the maximum, creating a sensation of rich tropical heat.

The period from June to August, which can tentatively be called the local "winter", brings only a slight and very pleasant decrease in temperatures. July is considered the coolest month with an average figure of +24.6°C. At this time, the daytime heat becomes milder, making conditions more comfortable for long walks and exploring the city. Mid-year night temperatures can drop to +21°C... +22°C, giving travellers a welcome freshness.

Daily temperature fluctuations in the region are moderate but still noticeable, especially during the dry season. The difference between the daytime maximum and the nighttime minimum is usually between 4 to 7 degrees. For example, in August, with daytime heating up to +28.5°C, the air can cool down to +21.7°C by night. On the whole, the weather remains favourable and predictable: there is no extreme cold here, and gentle warmth is maintained all year round.

The nature of precipitation in Atambua is determined by the tropical climate with a pronounced alternation of wet and dry periods. Precipitation here falls exclusively in the form of rain; snow does not occur in this region. Understanding the seasonality will help you properly plan your journey and prepare the necessary wardrobe.

The rainy season falls on the period from December to March. January is considered the wettest month, when rainy days can be registered almost daily (up to 31 days a month), although the total amount of precipitation in millimetres remains moderate. In February and March, the likelihood of getting caught in the rain is also very high — about 28-29 rainy days, so an umbrella and a raincoat will be indispensable.

The dry season, which is most favourable for tourism, lasts from May to September. During this time, the amount of precipitation decreases sharply. The driest month is August, when on average only one rainy day is recorded. June and July are also excellent for trips: rains during this period occur extremely rarely (only 4-5 days per month) and are usually short-lived in nature.

When preparing for a journey to Atambua, orient yourself towards the tropical climate: it is warm here all year round. The foundation of your wardrobe should consist of items made from light natural fabrics — cotton, linen, or viscose, which allow the skin to breathe at an average daytime temperature of around +26°C. Shorts, T-shirts, and loose-fitting dresses will become your best companions. For walking tours, be sure to bring comfortable footwear: reliable trekking sandals or light trainers in which your feet will not get tired.

It is important to consider the pronounced seasonality of rainfall when planning your luggage. From December to March, the wet season lasts, when it rains almost daily (up to 31 rainy days in January). During this period, a light rain poncho, quick-drying clothes, and perhaps a waterproof cover for your backpack are vitally necessary. From May to October, the dry period sets in, when there is almost no rain; at this time, the focus shifts to protection from the active sun. Be sure to take a wide-brimmed hat or cap, sunglasses, and cream with a high SPF factor.

Despite the daytime heat, in the evenings, especially from June to September, the temperature can drop to +21…+22°C. We recommend using the layering principle and packing a light sweatshirt, cardigan, or windbreaker in your suitcase. A long-sleeved shirt will also be useful for evening outings to protect not only against the slight chill but also against insects, so do not forget to stock your travel kit with quality repellents.
