Climate Chart of Maui (Hawaii), USA

Climate overview

Temperature

Monthly mean temperatures remain warm throughout the year, with the lowest monthly mean shared by January / February at 22.6 °C. The highest monthly mean arrives in August, at 26.6 °C. These are averages across each month, not daytime highs; they describe the broad temperature background rather than the full range visitors may experience on individual days. Across the calendar-month means, the unweighted average is 24.7 °C. This offers a compact sense of the overall temperature pattern, but it is not a day-weighted annual average and does not capture daily variability. For planning around cooler average conditions, the tied coolest months are the relevant reference, rather than treating the yearly mean as typical of every visit.

Rain

Mean daily rainfall is highest in February, at 2.42 mm/day. It is lowest in June, at 0.21 mm/day. These figures are daily means for the respective months, not monthly totals; the lower mean does not mean every day is dry or indicate how often rain falls. The unweighted average of the monthly mean daily rainfall figures is 1.21 mm/day. It helps place the monthly extremes in context, but does not describe the timing or frequency of rainfall on particular days, so visitors should not use it as a forecast.

Sunshine

Mean daily sunshine reaches its highest level in June, at 12.43 hours/day, and its lowest in December, at 9.11 hours/day. These averages can help with broad outdoor-planning expectations, but sunshine duration is not the same as day length and does not guarantee clear skies throughout a day. The unweighted mean across monthly sunshine averages is 10.76 hours/day per day. It provides an overview rather than a promise about conditions on a particular date, so flexible plans remain useful when outdoor time matters.
