The Solomon Islands hold WWII Pacific theatre relics across Guadalcanal's beaches, the saltwater shark-callers of Western Province, and the Marovo Lagoon stretching one of the world's largest enclosed reefs.
Drier season with Marovo Lagoon at peak diving, Guadalcanal's Bloody Ridge and Iron Bottom Sound dives accessible, and Western Province's Roviana Lagoon at its calmest.
Independence Day July 7 aside, the late dry season offers peak whale watching off Western Province and the calmest crossings to Tetepare and Rennell.
Wet season with cyclone risk in the south, but Honiara remains accessible and the country's interior rivers swell to their photogenic maximum.
Independence Day events fill Honiara, the rains tapering, and Western Province dive operators running their full schedules with shark-feeding sites at peak.
