In Samoa (formerly Western Samoa), an archipelago in the Pacific Ocean located south of the equator, the climate is tropical, that is, hot, humid and rainy throughout the year, with a maximum in rainfall from December to March, and a relative minimum from June to September.
Temperatures are stable and vary little between the hottest period (December to April), when highs are about 30 °C (86 °F), and the coolest period (June to September) when they are around 29 °C (84 °F). Temperatures at night are almost always above 20 °C (68 °F). The south-east trade winds blow steadily throughout the year, making the heat more bearable.
Here are the average temperatures of Apia.

The rains fall in the form of downpour or thunderstorm, intense but usually short-lived, except in the period from December to March, when they can sometimes last for several hours.
Rainfall is enhanced by the mountains that are found in the interior of the two main islands, and in particular the largest island, Savai'i, where Mount Silisili, 1,858 metres (6,096 feet) high, is located. Here the rains exceed even 5 metres (195 inches) per year.
In the capital Apia, in Upolu Island, 2,800 millimetres (110 inches) of rain per year fall, with a maximum of 450 mm (17.5 in) in January, and a minimum of 80 mm (3.2 in) in July and August. Here is the average precipitation.

The best time to travel to Samoa goes from June to September, being the least hot and the least rainy; however, even in this period, some downpours and thunderstorms must be put into account.


All year round, tropics-friendly, loose fitting clothing, sun hat, a scarf for the breeze, a light sweatshirt for the evening, a light raincoat or umbrella. For the mountains, hiking boots, fleece, raincoat.
