When are crowds lowest in Maui?

Search-interest seasonality (Google Trends 2021-2025) is lowest in October and peaks in August. Interest tracks both in-trip visitors and lead-time planners, so treat it as a "destination is on people's minds" signal rather than literal arrivals.

Which months in Maui have good weather but fewer tourists?

May (climate 10/10, crowd index 10) and June (climate 10/10, crowd index 16) — shoulder months with above-average climate and below-median search-interest. Often the best value-for-weather trade.

What is the UV index in Maui by month?

UV peaks at 11 (very high) in July and is lowest in December at 5 (moderate). Monthly peak values: Jan 6, Feb 7, Mar 8, Apr 9, May 9, Jun 10, Jul 11, Aug 11, Sep 10, Oct 8, Nov 6, Dec 5.

What is the UV index in Maui in July?

How high can UV get in Maui on the sunniest days?

Most days look like the monthly average, but on the sunniest ~1 in 10 days UV climbs higher than the mean suggests. August is the worst case: typical days average UV 11 (very high), but the top 10% of days reach UV 12 (extreme) — and even higher. Months where the sunniest days routinely exceed the typical reading: January, February, March, May, June, July, August, September, December. Plan sun protection for the worst case, not the average.
