Weather in Kotabaru

Be prepared for any of nature's surprises when travelling to Kotabaru. In this section, we have gathered the freshest weather data and detailed forecasts for you, which will help you plan the perfect journey.

The climate in Kotabaru can be described as typically tropical, with high humidity and consistently warm weather throughout the year. Here, one hardly feels the change of seasons in the conventional sense: the average air temperature holds steady at around +26...+27°C, and nights bring only a slight coolness. This is a place where eternal summer reigns, and sharp temperature fluctuations simply do not occur.

A characteristic feature of the local weather is the absence of a clearly defined dry season. Precipitation falls regularly throughout the year, and the number of rainy days remains high even in months like August and September. Rains here are a common occurrence that maintains the region's lush greenery, which is why Indonesia always looks vibrant and picturesque in this part of the country.

Tourists should be prepared for variable cloudiness and frequent rainfall regardless of their travel dates. However, thanks to the consistently high temperatures, the rains are usually perceived as a warm and refreshing addition to the tropical atmosphere, not hindering one from enjoying their holiday and nature.

The climate in Kotabaru is distinguished by an enviable consistency characteristic of equatorial latitudes. The division into four seasons, familiar to many, is practically absent here: throughout the year, the thermometer stays at consistently high marks. The average air temperature fluctuates within a very narrow range from +25.6°C to +27.1°C, making this region a kingdom of eternal summer where the weather is predictably warm regardless of the month.

The nominal peak of heat occurs at the end of the year, especially in November, when the average temperature reaches its maximum, and daytime figures often rise to +30.3°C. The "coolest" period can be considered the middle of the year — July and August. However, even at this time, average values are around +25.6°C, and during the day the air warms up to +28.5°C, so the concept of winter is completely absent in Indonesia, and travellers will not need warm clothing.

Daily temperature fluctuations make staying at the resort quite comfortable. While the sun warms the air up to +30°C during the day, creating a hot atmosphere, the nights bring pleasant freshness when the temperature drops to +23°C...+24°C. This is an ideal time for walks, although it is worth noting that due to the large number of rainy days, humidity remains high year-round, which may intensify the sensation of heat.

The climate in this region is characterized by stability and high humidity, so precipitation here is a frequent and quite familiar phenomenon. When planning a trip to Kotabaru, it is worth considering that it rains regularly throughout the year. Judging by meteorological data, the amount of precipitation in millimetres is not large, but it falls with enviable consistency: practically every month, 20 to 30 rainy days are recorded.

The wettest period, judging by the frequency of rains, falls in the first half of the year. The record holder is March, when precipitation can be observed literally every day (up to 30 days in the month). January, February, and May are not far behind in this regard. The nature of the precipitation, considering the small volume of moisture with high frequency, resembles short-term rains or light drizzle rather than prolonged tropical downpours.

Some decrease in precipitation activity is observed closer to the end of summer and the beginning of autumn. The "driest" months can be called August and September, when the number of rainy days decreases to 20–22, and the volume of precipitation drops to a minimum (about 4–5 mm). Nevertheless, even at this time in Indonesia, the probability of rain remains high, so an umbrella or raincoat will be useful for the traveller in any season.

When preparing for Kotabaru, you should orient yourself towards the hot and humid climate characteristic of this region. Since the air temperature here is stable throughout the year and stays in the range of +23…+30°C, the foundation of your wardrobe should be light items made from natural breathable fabrics, such as cotton or linen. T-shirts, shorts, loose trousers, and summer dresses will ensure comfort even on the warmest days. Avoid heavy synthetics, as they can cause discomfort in high humidity.

Particular attention should be paid to protection from moisture, as rainy days in Kotabaru are a frequent occurrence in any month of the year (from 20 to 30 days with precipitation monthly). Be sure to pack a light raincoat or a compact umbrella in your suitcase, which should always be at hand. Choose footwear that is comfortable for walking and water-resistant: quick-drying sandals or light trainers that you don't mind getting wet are ideal. It is not worth taking bulky rubber boots — it will be too hot in them.

Despite the cloudiness and rains, the sun in Indonesia is very active, so do not forget sunscreen with a high SPF factor, a hat, and quality sunglasses. It is also recommended to take a light long-sleeved shirt: it will be useful not for warmth, but for protecting the skin from sun rays during long walks or from the cool air conditioning in transport and shopping centres.
