The climate of Gizo
Gizo, located in the Solomon Islands, predominantly features an tropical rainforest climate, recognized as Af in the Köppen climate classification. Geographically, Gizo is located on an island close to the equator, contributing to its year-round warm climate. Constantly high temperatures mark the Gizo climate, with a slight fluctuation between the coldest month with a minimum of 23°C (73.4°F) and the hottest month with a maximum of 31°C (87.8°F).
The rainfall in Gizo is abundant and evenly distributed over the years, diminishing the significant differences between dry and rainy seasons typically seen in other tropical climates. The monthly rainfall varies from a low of 246mm (9.69") to a high of 396mm (15.59"), indicating the absence of a definitive dry season. The number of rainfall days throughout the year ranges from 18 to 22, reaffirming the perennial wet conditions of the region.
An oscillation in daylight hours from 11.7 hours to 12.6 hours is seen over the year, which is relatively consistent due to Gizo's equatorial position. The sea temperature also fluctuates mildly over the year, swinging from a low of 28.3°C (82.9°F) to a high of 30.3°C (86.5°F).
