Introduction

---

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, with little variation 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.
Rainfall occurs in the form of downpours or thunderstorms, which are 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 is located, 1,858 meters (6,096 feet) high. Here, the rains even exceed 5 meters (195 inches) per year.

Apia

In the capital, Apia, on the north side of Upolu Island, 2,800 millimeters (110 inches) of rain fall per year, 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.

Here are the average temperatures of Apia.

The sea in Samoa is warm enough to swim in all year round, as we can see in the following table.

Tropical cyclones

The Samoa Islands are exposed to the tropical cyclones of the South Pacific. Cyclones are usually formed from November to mid-May, though they are most likely from late December to early April. Outside of this period, there has been cyclone Keli, in June 1997.

Best Time

---

The best time to travel to Samoa is from June to September, since it is the least hot and the least rainy period of the year. However, even in this period, some downpours and thunderstorms must be put into account.
