The Solomon Islands experience a tropical climate year-round, characterized by warm temperatures, high humidity, and distinct wet and dry seasons. Located near the equator in the South Pacific, the islands maintain consistently warm conditions throughout the year with average temperatures ranging from 27°C to 31°C (81°F to 88°F). The climate is influenced by the northwest monsoon and southeast trade winds, creating two main seasons: a wetter period from November to April and a drier season from May to October. The wet season (November-April) brings heavy rainfall, high humidity around 80-85%, and occasional tropical cyclones, particularly between December and March. During this time, temperatures peak and conditions can be quite humid. The dry season (May-October) offers more pleasant weather with lower rainfall, slightly cooler temperatures, and humidity levels around 70-75%, making it the most popular time for visitors. The southeast trade winds during this period provide comfortable breezes that moderate the tropical heat.

Best Time to Visit

Beach & Relaxation
June through September offer the best beach conditions with calmer seas, less rainfall, and pleasant temperatures ideal for swimming, snorkeling, and diving in crystal-clear waters.
Cultural Exploration
May to October provides comfortable conditions for visiting villages, attending traditional ceremonies, and exploring historical WWII sites without the heavy rains that can impede travel between islands.
Adventure & Hiking
July and August are optimal for trekking and jungle exploration, as trails are less muddy and the drier conditions make outdoor activities more enjoyable while still maintaining lush tropical scenery.
Budget Travel
January through March (excluding holidays) and November offer lower accommodation rates and fewer tourists, though you'll need to prepare for wet weather and occasional travel disruptions.
