Kupang, located in the southern part of Indonesia, welcomes travellers with a classic tropical climate. Eternal summer reigns here: air temperature remains surprisingly stable throughout the year, varying on average from +26°C to +28°C. Thanks to its proximity to the equator, you will not encounter sudden cold snaps, making this city an attractive destination for those seeking warmth at any time of year.

Weather in Kupang has distinct seasonality, divided into dry and wet periods. The dry season, which lasts roughly from May to October, is a time of cloudless skies and minimal rainfall. In months such as July and August, rain is extremely rare, creating ideal conditions for beach holidays and exploring local attractions under the bright sun.

The rainy season usually begins in November and peaks from December to March, when the number of rainy days increases significantly. During this period, nature comes alive, becoming greener and lush, but tourists should be prepared for frequent and heavy rainfall. Nevertheless, even in the wettest months, the air remains warm, and tropical downpours are often followed by clear spells.

Kupang welcomes travellers with consistently hot weather year-round, characteristic of equatorial latitudes. The temperature regime here is distinguished by enviable constancy: average figures rarely drop below comfortable levels. The hottest months are October and November, when the thermometer confidently reaches the 31°C mark during the day. At this time, the sun is particularly active, so tourists are advised to plan long walks for the morning or evening hours.

The nominal "winter" in this region of Indonesia falls in July and August, although there is no cold weather here. During this period, it only becomes slightly fresher: the average temperature drops to 26°C, and night-time minimums can reach 23°C. This time is considered one of the most comfortable for visiting, as the heat is much easier to bear, and the air becomes less humid compared to the rainy season.

Daily temperature fluctuations in Kupang are moderate but perceptible to the body. The difference between the daily maximum and nightly minimum is usually about 5–7 degrees, especially in the dry season (September-October). At the beginning of the year (January-February), when humidity is high, nights remain very warm (about 25°C), creating a "steam room" effect, whereas in the dry months, evening coolness brings pleasant relief after a sunny day.

In Kupang, there is a distinct division of the year into wet and dry seasons, which is characteristic of the tropical climate of this part of Indonesia. The rainy season here usually lasts from December to March. During this period, precipitation falls with enviable regularity: January is the peak month, when up to 30 rainy days are recorded. February and March are also characterised by high humidity, so travellers planning a trip at the beginning of the year should be prepared for frequent rains.

The dry season begins in May and continues right through to October, creating ideal conditions for beach holidays and walks. The driest months are considered to be July and August, when rainfall tends towards zero, and the number of rainy days is minimal (only 1–2 days per month). At this time, the weather is most stable and favourable for tourism.

Transitional periods, such as April and November, are characterised by changing weather conditions. In April, the number of wet days decreases to approximately two weeks, while in November, conversely, it increases to 18 days, heralding the return of the rainy season. Thus, the character of precipitation in Kupang changes from almost daily rains in winter to complete drought in the middle of summer.

Since hot weather reigns in Kupang all year round with an average temperature of about +26…+28°C, the basis of your wardrobe should consist of light and breathable items. Give preference to loose clothing made from natural fabrics, such as cotton or linen, preferably in light shades to avoid overheating in the sun. Shorts, T-shirts, and summer sundresses will be most appropriate, but do not forget a wide-brimmed hat, sunglasses, and high SPF cream, as solar activity in Indonesia is very high.

When planning a trip, it is important to consider the seasonality of rainfall. If you are setting off on a journey in the period from December to March, be prepared for high humidity and frequent rains (up to 30 rainy days per month), so a light raincoat or a compact umbrella will become mandatory attributes in your luggage. In the dry season, which lasts from May to October, precipitation is extremely rare, and one can safely get by with only summer clothing, however, a light cover-up with long sleeves will still be useful for protection from the scorching sun or the cool air from air conditioners in transport.

For comfortable exploration of the city and its surroundings, choose comfortable footwear: reliable sandals or light breathable trainers are suitable for long walks, while flip-flops will come in handy for the beach. It will also not be superfluous to take insect repellents with you, as insects can be active in the evening, especially during the wet season. Given the consistently high night-time temperatures (about +23…+25°C), you are unlikely to need warm clothes, but the principle of layering will help you feel comfortable when changing environments from the hot street to an air-conditioned room.
