Pago Pago, located in American Samoa (USA), features a typical tropical climate. Temperatures here remain surprisingly stable throughout the year, with averages fluctuating within a comfortable range of approximately 26.5°C to 27.5°C. This means travellers can expect consistently warm weather regardless of the time of their visit.

There are practically no sharp seasonal temperature fluctuations in Pago Pago, making the climate very even. However, a characteristic feature of the weather is high humidity and frequent rainfall throughout the year. Although the monthly amount of precipitation is not extremely high (a maximum of about 18 mm in February), the number of rainy days remains significant, varying from 19 to 28 days per month. This suggests that frequent, but usually very light rain or drizzle, is a common occurrence, especially between December and February, when the highest amount of precipitation and rainy days are recorded.

Thus, when planning a trip to Pago Pago, one should expect constantly warm and humid weather. Light, breathable clothing, a hat for sun protection, and an umbrella or light raincoat will come in very handy. Despite the frequent but light precipitation, the consistently high temperatures make Pago Pago an attractive destination at any time of the year for those who love tropical exoticism and are not afraid of refreshing humidity.

In Pago Pago, the temperature regime is distinguished by enviable consistency throughout the year. The annual range of average temperatures is very narrow, fluctuating only from 26.5°C to 27.5°C. March and April are traditionally considered the warmest months, when the average temperature reaches 27.5°C, and maximum daytime values can rise to 28.4°C. It gets slightly cooler, if one can say so in the tropics, in July and August, when the average temperature is about 26.5°C, and nightly lows may drop to 25.9°C.

The so-called "summer" or warmer period in Pago Pago covers the months roughly from November to May. At this time, average daytime temperatures confidently stay in the range of 26.9°C - 27.5°C, and maximum values regularly reach 27.7°C - 28.4°C. Given the high humidity characteristic of the region, the weather during these months feels hot and very humid, creating the typical atmosphere of a tropical paradise. Night-time temperatures also remain high, rarely dropping below 26.1°C - 26.6°C, ensuring warm nights.

During the period from June to October, a nominally "cool" season sets in Pago Pago, although the air temperature remains very comfortable and warm. Average values in these months range from 26.5°C to 27.2°C, with maximum daytime readings around 27.1°C - 27.9°C. An important feature of the climate in Pago Pago is the insignificant temperature fluctuation between day and night. The difference between daily maximum and minimum temperatures usually does not exceed 1-2 degrees Celsius, which means there is no sharp night-time cooling and the weather remains consistently warm around the clock.

In Pago Pago, precipitation falls year-round, and there is no distinct dry season in the traditional sense. A characteristic feature is the very high frequency of rainy days, however, the total amount of precipitation in millimetres remains moderate. This suggests that frequent but predominantly light rains or drizzle are typical for Pago Pago, rather than heavy downpours. Snow, given the tropical climate, does not fall here.

Regarding the periods with the highest amount of precipitation, February stands out as the wettest month in terms of moisture volume, with an average figure of 18 mm. It is followed by January (13 mm) and December (12 mm). In terms of the number of rainy days, January and December lead, each averaging 28 days with precipitation. A fairly large number of rainy days (25-26) also occur during the period from February to May and in October. Even in these wetter months, the nature of the precipitation remains predominantly light.

The lowest amount of precipitation in Pago Pago is usually observed in June and August, when only about 4 mm falls on average per month. August is also the month with the fewest rainy days — an average of 19 days. Slightly more precipitation, an average of 5 mm per month, falls in March, July, and September. In March, there are on average 25 rainy days, in July – 24 days, and in September – 20 days. It is important to understand that even in these nominally "drier" months, the probability of catching rain remains high; it may simply be even less intense and prolonged.

When planning a trip to Pago Pago, it is important to consider its tropical climate with constantly warm weather and high humidity year-round. 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 skirts will be the most comfortable. Since the temperature remains practically unchanged throughout the year, you will not need warm clothing, even in the evenings. The average temperature stays around 26.5°C - 27.5°C, making layering unnecessary.

Despite the fact that the total amount of precipitation in millimetres is small (from 4 mm to 18 mm per month), the number of rainy days in Pago Pago is very high – from 19 to 28 days per month. This means that light rain or drizzle can catch you on any day. Therefore, be sure to take a light raincoat or a compact umbrella. High SPF sunscreen, headwear (a hat or cap), and sunglasses are also mandatory attributes, as the sun in the tropics is very active, even on cloudy days. Don't forget comfortable footwear: sandals, flip-flops, and perhaps light waterproof trainers or aqua shoes, especially if you plan nature walks or coastal strolls.

Although the seasons in Pago Pago do not have sharp distinctions, the periods from December to February are characterized by a slightly higher amount of precipitation (up to 18 mm in February) and the maximum number of rainy days (up to 28). While June and August are considered months with the least amount of precipitation (about 4 mm) and rainy days (about 19-21). However, these differences are minimal, and the basic set of items remains relevant year-round. The main thing is to be prepared for warmth, humidity, and frequent, but usually not strong, refreshing rains.
