February has hot and humid conditions in American Samoa as the average temperatures register in the steady 77°F (25°C) to 88°F (31.1°C) range. Heatwaves are generally uncommon, but the humidity keeps the conditions oppressive. Swimming or surfing in mild ocean waters is the best way to counter the heat. Mornings and evenings provide comfortable weather to venture out in search of the diverse marine life on the islands or to explore the moderately high hills and mountains. The average sea temperatures of 84°F (28.9°C) are perfect for sailing, snorkeling, and exploring the underwater sea life that is difficult to find elsewhere in the North American winter. Volcanic fog is a queer phenomenon at higher elevations. The rainforests are home to fruit bats, lorikeets, shrikebills, ground-doves, and many other birds and animals. February nights are comfortably warm in the hot summer of American Samoa.
