Pick your travel dates to see the odds.
April is Maui's rainiest month on average, with 18.2 rain days, though highs warm to 73.5°F and the sea climbs to 78.1°F.
Humidity eases slightly to 76%, and the extra rain tends to arrive as frequent, short showers rather than storms that wash out a full day.
Whale watching winds down through April as the humpback population begins its migration back to Alaska; some tours continue into early May, but sighting odds drop noticeably compared to peak winter months.
No hurricane activity is recorded historically for April, and Central Pacific storm season remains two months away.
The lush, green landscape from the season's rain makes April a particularly good month for waterfall hikes along the Road to Hana or in the Iao Valley, before the drier summer months.
Snorkeling conditions at Molokini Crater and along Kaanapali's reef improve as the sea warms out of its winter low.
This is a shoulder-season month for pricing and crowds compared to the winter peak, making it a reasonable window for value if the higher rain-day count isn't a dealbreaker.
Pack a rain layer for the frequent showers, plus reef-safe sunscreen and swimwear as the water warms toward summer conditions.
