The best month for cruise weather in Honiara (Guadalcanal) is July, rated 79 out of 100 (Good): calm seas and warm water. June and August score nearly as well.

How the rating works

Each month scores out of 100 from five things: the average high (30 points; 64 to 82°F is full marks), how often it rains (25), how rough the sea gets (15), how warm the water is where swimming matters (10) and storms (20: how often a tropical storm passed within 90 miles since 1980, or how often gales struck in the 20-year record, whichever is worse). A part with no data is left out and the rest scaled up. The weights are a judgment about what makes a stop pleasant, not a measurement. Crowds and fares are not included.

These are averages for 2006–2025 (20 years) from ECMWF’s ERA5 climate record, adjusted to local detail with a higher-resolution ECMWF analysis and Météo-France waves, then checked against weather-station records from NOAA (GHCN-Daily). There is no suitable station near this port, so the check was between the two model sources. They differ a lot, which can happen near fjords, mountains and small islands, so read these figures as rough.
