Solomon Islands in January

April through October offers the driest weather and calmest seas — crucial for diving and inter-island travel. May and June are particularly good, with visibility underwater reaching 40+ meters and minimal rainfall. But even 'dry season' means occasional downpours. November through March brings cyclone season and daily thunderstorms that can strand you on islands for days. Water temperatures stay around 28°C year-round, perfect for diving without thick wetsuits. Trade winds pick up from June to August, making surface conditions choppy but providing relief from humidity. If you're here for WWII history, any time works since most sites are accessible year-round. Just remember that weather delays are part of the Solomon Islands experience regardless of season.
