Været i Savai'i (Savaii) i desember

Samoa's forum is direct that Savai'i runs wetter than neighboring Upolu, and rain is a real possibility here pretty much year-round even if it's rarely heavy. March sits near the tail end of the rainy season, with posters describing a pattern of showers more likely in the early morning and evening, leaving the middle of the day drier - though heavier overnight rain is still possible. Regulars recommended packing a raincoat as routine gear rather than a special precaution, since most rain here comes in short bursts that don't really derail a day's plans.

Forum posters describe September as sitting outside Samoa's full wet season (October through April), meaning tropical showers are still likely but generally not severe enough to disrupt a trip, with sunshine and warmth typically dominating. Posters do flag Savai'i specifically as prone to rain more or less regardless of season, though usually not heavy - a real contrast to the somewhat drier reputation of the more developed Upolu. Posters note weather can differ meaningfully between the north and south coasts and between islands, and describe Samoa's weather generally as becoming less predictable in recent years, with one visitor reporting a run of hot September days interrupted by an unexpected mini-cyclone.
