When is the best time to travel to Maui in the Spring if we want to be warm?
Maui is warm all year. If you want to go someplace cold, Maui would not be the place to go.
April and May are both warm (low 67 deg F, high 84 deg F). May has a little less rain on the average, but less than an inch even in April. It is a little hotter in July (up to about 88 deg F) but really there is not that much temperature variation.
I think any time in Spring is good. 🌴
