Weather in January

January is situated right in the heart of summer for American Samoa and is characteristic of the wet season that the islands experience during this time. As one of the wettest months, January witnesses frequent, albeit brief, thunderstorms. The temperatures during January usually oscillate between 77°F and 90°F, making it one of the warmer months of the year.

Situated in the southern hemisphere, American Samoa's January weather is quite the opposite of what many northern regions experience during this time. The month sees an increase in humidity, often making the days feel even warmer than the thermometer suggests. The combination of high temperatures and increased rainfall contributes to a pronouncedly humid and damp atmosphere.

Compared to December, January generally maintains similar temperature ranges but might see a slight uptick in the frequency of rainfall events. Looking forward to February, weather conditions are expected to remain consistent, with both temperatures and rainfall levels being comparable.

While the entire archipelago experiences uniformly tropical conditions, certain areas like the Pago region, being closer to mountainous terrains, may receive more rainfall due to the orographic effect. In terms of extremes, Malaeloa / Aitulagi holds the records for temperatures in American Samoa, but January doesn't typically approach these record values.

Though January is a wet month, the marine biodiversity remains vibrant and can be appreciated by those willing to explore underwater. However, potential visitors should be cautious, as the risk of tropical cyclones remains, which is common for the South Pacific region during this period.
