Weather in Apia

Planning a trip or just interested in the weather in Apia? Here you will find the most up-to-date information: current weather conditions, detailed forecasts, and clear charts to help you stay informed of all changes.

Apia, the capital of Western Samoa, is characterized by a distinct tropical trade-wind climate. This means it is warm and humid year-round, with minimal temperature fluctuations. Average monthly temperatures remain consistently in the range of 25.6°C to 26.7°C, creating a feeling of eternal summer. Daytime highs usually reach 27-28°C, while nighttime lows rarely drop below 24-25°C.

In Apia, there is no sharp change of seasons familiar to temperate latitudes. However, two conditional periods can be distinguished, differing mainly in the amount of precipitation. Although it rains very frequently throughout the year (from 24 to 30 rainy days per month), the months from December to February tend to bring slightly more rainfall (for example, about 12 mm falls in January, and 15 mm in February). The period from June to September is considered slightly "drier," with the least amount of precipitation (e.g., 4 mm in August and September). It is important to understand that even in the "dry" season, rain remains a frequent occurrence; it may simply be less intense or prolonged.

Thus, the weather in Apia is distinguished by high temperature stability and constant high humidity due to frequent rainfall. When planning a trip, it is worth being prepared for a warm and humid environment, regardless of the time of year, and carrying light clothing and rain protection.

The temperature regime in Apia is notable for its enviable stability throughout the year, which is typical for a tropical trade-wind climate. The annual course of average temperatures is very smooth: from 25.6°C in August, considered the "coolest" month, to 26.7°C in March and April – the peak warm months. Maximum daytime temperatures in March can reach 28.3°C, while minimum nighttime temperatures in August drop to 24.3°C. Thus, even between the warmest and coolest periods, the difference in average temperatures is little more than one degree.

The period roughly corresponding to "summer" in northern latitudes (although seasons are weakly expressed in Apia), approximately from December to May, is characterized by consistently hot and humid weather. Average daytime temperatures during these months range from 27.8°C to 28.3°C, and nighttime temps from 24.7°C to 25.3°C. The conditional "winter," falling on June-September, brings only a slight softening of the heat. During this time, daytime highs average 26.9°C - 27.4°C, and nighttime lows are 24.3°C - 24.8°C, which still ensures very warm weather.

One of the characteristic features of Apia's climate is the insignificant diurnal temperature fluctuations. The difference between average daytime highs and nighttime lows throughout the year rarely exceeds 2.5 - 3.2 degrees Celsius. This means that evenings and nights bring a pleasant, but not sharp, coolness after the daytime heat. Such an even temperature background, without extreme peaks of heat or periods of cold, makes the climate of Apia comfortable for lovers of tropical warmth all year round.

Precipitation in Apia is a practically year-round phenomenon, confirmed by the high number of rainy days each month. Even during the "driest" periods, it rains most days of the month. The city does not experience a pronounced dry season characteristic of many tropical regions; rather, periods with slightly higher or lower total rainfall are observed here.

The highest amount of precipitation usually falls from December to February. February stands out as the wettest month with an average figure of 15 mm of rainfall, with rain occurring on about 28 days. January and December also bring significant moisture, with 12 mm and 10 mm of precipitation respectively, and an impressive 30 rainy days in each of these months. The "driest" months, if one can call them that, are August and September, when only 4 mm of precipitation falls. Nevertheless, even in these months, there are about 24 rainy days. June is also characterized by relatively low rainfall levels – 5 mm.

A characteristic feature of the precipitation regime in Apia is the combination of very high rain frequency (from 24 to 30 days per month) with moderate total monthly amounts. This suggests that precipitation most often falls in the form of frequent, but not always prolonged or very intense tropical showers. Thus, when planning a trip to Apia at any time of year, it is worth being prepared for regular rains, which are an integral part of the local climate.

When packing for Apia, remember that a typical tropical climate awaits you: warm and very humid year-round. The average temperature stays in a comfortable range of 25-28°C, so the basis of your wardrobe should be light, breathable clothing made from natural fabrics such as cotton or linen. Shorts, T-shirts, sundresses, light trousers, and shirts will be most appropriate. Given that rain in Apia is a very frequent occurrence (from 24 to 30 rainy days per month year-round), a compact umbrella and a light raincoat or poncho will become your indispensable companions. Although rainfall is slightly higher from December to February (for example, up to 28 rainy days in February), readiness for a sudden downpour is important at any time of year.

Besides clothing, pay close attention to sun protection: high SPF sunscreen, headwear (a wide-brimmed hat or panama hat), and high-quality sunglasses are mandatory for a comfortable stay under the active tropical sun. For walking around the city and its surroundings, choose maximally comfortable footwear – sandals, light breathable sneakers, or flip-flops that are not afraid of moisture and dry quickly. Insect repellent will also be useful, especially for evening walks. Since the air temperature is consistently high year-round, the principle of layering for warmth is unlikely to be needed; rather, a light cover-up or long-sleeved shirt will come in handy for sun protection or when visiting air-conditioned premises.
