Climate overview
Temperature
Monthly mean temperatures are lowest in February, at 22.6 °C, and highest in both August / September, at 26.5 °C. The annual unweighted mean of monthly means is 24.6 °C. These are averages for each month, not daytime maximum temperatures, so they do not describe the full range visitors may encounter during a day.
Rain
Mean daily rainfall is highest in March, at 1.84 mm/day, and lowest in July, at 0.79 mm/day. The unweighted mean across monthly means is 1.25 mm/day per day. These daily averages are not monthly totals and do not show how often rain falls; even a month with a lower mean does not guarantee rain-free days.
Sunshine
Average daily sunshine reaches its highest level in June, at 12.41 hours/day, and its lowest in December, at 9.20 hours/day. The unweighted mean across monthly values is 10.79 hours/day per day. Sunshine duration can help with broad outdoor-planning expectations, but it is not the same as day length and does not guarantee clear skies on a particular day.
Best Travel Time Guide for Honolulu, USA: Ideal Seasons and Weather Insights
Visitors prioritising cooler monthly averages could consider February, when the monthly mean is 22.6 °C; this is an average, not a promise about daytime highs or conditions on a specific date. For lower average daily rainfall, July is the conditional option, with 0.79 mm/day; by contrast, prepare for the higher monthly mean in March, at 1.84 mm/day. These averages do not indicate the frequency of wet days, so packing for variable conditions remains sensible. For outdoor plans guided by average sunshine duration, June has the highest mean at 12.41 hours/day, while December has the lowest at 9.20 hours/day. This is a daylight-planning reference, not a measure of day length or a guarantee of sunshine during a visit.
