The best season for waves is October to April when the North Pacific awakens. Long period ground swells regularly hit exposed north facing coasts including Malaita, Ysabel and Makira. The same swells which hit the North Shore of Hawaii reach the Solomons some days later – at reduced size and very long period. Swell is usually 3 to 6 feet but can be bigger.
There are also less consistent southerly swells from the Coral Sea which reach south facing islands including Gizo and South Guadalcanal. The swell window between Australia and New Caledonia is quite narrow but straight southerly swells that tend to miss the east coast of Australia in late winter can sometimes reach the Solomons. Tropical depressions in the coral sea and Western Pacific can generate localised swell from the north and south.
