Climate and monthly weather forecast
Solomon Islands

The Solomon Islands, located in Oceania, is an archipelago composed of six major islands and over 900 smaller ones. With a total land area of 28,896 square kilometers, it is largely dominated by mountains covered in dense tropical rainforests. Its geographical proximity to the equator means that the Solomon Islands experiences a Tropical Rainforest Climate, characterized by high temperatures, extreme humidity, and copious rainfall throughout the year. Monthly temperatures rarely vary, with averages hovering around 27°C (80.6°F) to 32°C (89.6°F). The warm, moist conditions contribute to the islands' biodiversity, promoting lush greenery and supporting a vast array of plant and animal life. Precipitation is consistently high, averaging approximately 3,0mm (0") annually. However, the western side of the islands can see rainfall up to 5,0mm (0") due to orographic rainfall effects.

Ideal visiting conditions in the Solomon Islands depend largely on personal comfort regarding humidity and rainfall. Generally, April to November is considered the most favourable period. During these months, the islands experience marginally less rainfall, with temperatures ranging from 24°C (75.2°F) to 30°C (86°F). The sea is particularly enticing during this period, with water temperatures at a steady 26°C (78.8°F) to 29°C (84.2°F), perfect for snorkeling, diving, or simply enjoying the pristine beaches. During this period, visitors also have the opportunity to partake in various cultural festivals that take place.

Given the consistency of the Solomon Islands' tropical climate, there are no periods of severe weather that would deter tourists completely. However, the months from December to March tend to be wetter, with slightly higher temperatures and humidity.

Thus, if visitors have a low tolerance for high humidity and rainfall, they may find this period less comfortable for travel.
