The weather is idyllic year-round on Maui, so there's really no bad time to come. Summer and winter temperatures vary only by a few degrees so Hawaii’s Valley Isle offers an enticingly-warm, beachfront escape at any time.
At the resorts clustered in South Maui (Wailea/Kihei) and West Maui (Lahaina/Kaanapali), expect the warmest temperatures in July and August. January and February are only a few degrees cooler; the winter months see more rain, but also better surf conditions and great opportunities for whale-watching.
With Maui being relatively close to the equator, there’s relatively little variation in daylight hours across the year. Resort sunset ceremonies begin between 5:30pm and 6:30pm with the blowing of a conch shell (pu in Hawaiian), followed by a traditional chant and the lighting of tiki torches.
With such slight variations in the weather, deciding when to travel to Maui will usually boil down to the best time for particular activities. Here’s what to expect from Maui month by month.
Editor's note: during COVID-19 there are restrictions on travel and opening hours may vary. Check the latest guidance before planning a trip, and always follow local health advice. Events may be subject to change.
Best time for whale watching: December–March
Understandably, Maui is a busy place during the holiday season and at New Year, when winter is at its worst in many parts of the world. There's more rain than in summer, but it's still warm, and for those escaping frigid, snowy weather back home, winter coincides with the peak season for whale-watching and surfing.
Between November and March, 10,000-15,000 humpback whales migrate from Alaska to Hawaii to mate, give birth and tend to their newborn calves. Their favorite gathering spot is in the shallow waters of the Auau Channel southwest of Maui, making for easy whale encounters.
“My favorite two weeks are the last week of December and the first week of January,” says Daniel Sullivan, a professional photographer who leads whale photography tours in a Zodiac boat. “Literally, there’s whales breaching everywhere. One time, I encountered 54 breaches in a row. It was just amazing.”
Best time for scuba diving and relaxing on the beach: June–August
The Valley Isle also gets very busy in the summertime. At the height of the summer season, daytime highs hover around 87°F, dropping to 73°F overnight. With abundant sunshine, sunbathers flock to the beaches and snorkelers come out in droves to view the colorful fish and green sea turtles that gather near the coral reefs, just a few yards from the beach.
Summer is when the water tends to be clearest so this is the best time for scuba diving. Key considerations in choosing when to venture into the ocean include cloud cover, which decreases underwater visibility, and wind, which also can decrease clarity.
Visitors making the journey inland to Haleakalā National Park should prepare for very different weather conditions. On days when it’s beach weather at sea level, it can be 30°F at the volcano’s 10,023ft summit, a prime location for watching the sunrise.
When summiting the volcano, dress appropriately; as a gauge, expect the temperature to drop several degrees for every 1,000ft (300m) increase in altitude. The National Weather Service provides an online forecast for the summit (see the "Detailed Forecast" section) or you can view live conditions on the Crater Cam, though the weather can change dramatically during the drive from the oceanfront to the summit.
Best time for lower prices and avoiding crowds: April–May and September–November
Spring and fall see a modest drop in visitor numbers. Hoteliers on Maui don’t really recognize seasonal differences as they do elsewhere in the world, since visitor numbers stay relatively strong regardless of the month, but the low season means quieter beaches, shorter lines at popular restaurants and, sometimes, a drop in room rates. The weather is still warm, and there's less rain than in winter.
January
While January is statistically a “rainy” month, umbrellas are seldom needed. On average, rain falls on just six days during the month. The Sentry Tournament of Champions, a stop on the PGA Tour, comes to Kapalua.
