Weather in Koror

Planning your day in Koror or preparing for a trip? In this section, you will find the latest weather information, including current data, forecasts, and clear charts to ensure your stay is as comfortable as possible.

Koror, located in Palau, is characterized by a typical tropical climate. This means the weather remains warm and humid throughout the year. The average annual temperature fluctuates very little, staying within a comfortable range of around 27°C, making the city attractive to visit at any time of year.

There are no distinct seasons in Koror as found in temperate latitudes. Air temperature is practically the same from month to month, with minimal fluctuations between daytime and nighttime readings. Precipitation falls regularly throughout the year, although the amount may vary slightly. For example, March sees the least amount of rainfall (about 6 mm), while July can be slightly rainier (about 16 mm). The number of rainy days is also quite high year-round, indicating high humidity.

Thus, when planning a trip to Koror, be prepared for warm, humid weather with frequent but often short-lived rains. Temperature fluctuations are minimal, so when choosing clothes, focus primarily on light, breathable fabrics and protection from the sun and sudden showers.

The temperature pattern in Koror is remarkably stable throughout the year, which is characteristic of the tropical climate of Palau. Average monthly temperatures fluctuate within a very narrow range, predominantly from 26.9°C to 27.6°C. This means travellers can expect consistently warm weather, regardless of the month chosen for their visit. Maximum daytime temperatures usually reach between 27.8°C (in February) and 28.6°C (in May), while nighttime lows rarely drop below 25.9°C (in July), creating comfortable conditions even after sunset.

If we were to distinguish the warmest and slightly cooler periods, May can be considered the month with the highest averages (around 27.6°C), when the daytime maximum can reach 28.6°C. The "coolest" month, if one can say so in tropical conditions, is February with an average temperature of 26.9°C and maximum daytime values around 27.8°C. However, it is important to understand that the difference between the warmest and "coldest" month is less than one degree Celsius, which once again highlights the exceptional uniformity of the climate. The weather in Koror feels very warm and usually humid all year round.

Temperature fluctuations between day and night in Koror are also minimal. The difference between the daily maximum and minimum temperatures is usually only about 1.7°C - 2.3°C. This means that evenings and nights remain very warm, and significant cooling after sunset should not be expected. This stability makes planning your wardrobe for the trip quite simple: light, breathable clothing will be appropriate at any time of day throughout the year.

The precipitation pattern in Koror is characterized by high humidity and frequent rains throughout the year, which is typical for the tropical climate of Palau. Almost every month features a significant number of rainy days, and the city does not experience a distinct dry season in the traditional sense. Rather, one can speak of periods with slightly more or less rainfall, but the chance of rain always remains.

Looking at the annual cycle, July stands out as the wettest month: on average, about 16 mm of precipitation falls, and the number of rainy days reaches 30, meaning it rains practically every day. Conversely, March is considered the month with the least rainfall — only about 6 mm. However, even in March, as in February (9 mm of precipitation), there are approximately 22 rainy days, emphasizing the constant presence of moisture in the air and the regularity of rainfall. Other months, such as May (12 mm), June, August, and September (11 mm each), also demonstrate a substantial amount of precipitation and a high frequency of rainy days, ranging from 25 to 28 days.

The nature of precipitation in Koror is predominantly tropical rain. Given the large number of days with precipitation alongside relatively moderate monthly volumes, it can be assumed that these are often short but regular downpours or drizzling rains typical of equatorial latitudes. Naturally, there is no snow in Koror. Travellers planning a trip should be prepared for a high probability of rain at any time of year by bringing a light raincoat or umbrella, although the intensity and duration of the rainfall may vary.

When planning a trip to Koror, it is important to consider its tropical climate, characterized by consistently high temperatures and humidity year-round. The foundation of your wardrobe should be light, breathable clothing made from natural fabrics such as cotton or linen. T-shirts, shorts, sundresses, and light trousers will be the ideal choice. Don't forget swimwear, as Palau is famous for its water recreation opportunities. Be sure to bring headwear (a hat or cap), sunglasses, and high SPF sunscreen to protect against the intense tropical sun.

Given that there is a high probability of precipitation in Koror almost all year round (from 22 to 30 rainy days per month), a light raincoat or a compact umbrella will become your indispensable companions. Although the monthly rainfall amount is not extreme (from 6 mm to 16 mm), frequent, albeit short-lived, rains are a common occurrence. Take care to bring comfortable footwear: light sandals, flip-flops for the beach, and perhaps a pair of closed but quick-drying shoes for walking will be very useful. Since the air temperature rarely drops below 26°C even at night, you are unlikely to need warm clothes, but a light cover-up or long-sleeved shirt may be useful for sun protection or in air-conditioned rooms.
