Maui contains a number of microclimates. It is generally drier on Maui’s leeward side where you’ll find the spectacular beaches and resorts of Kapalua, Kaanapali, Lahaina, Kihei and Wailea along the western coast. On the wetter windward side you’ll find lush Iao Valley and the scenic road to Hana. It’s warmer along the coast than Upcountry Maui where temperatures are typically 8-10 degrees cooler. If you’re driving up to the 9,740-foot Haleakala Visitor Center atop Haleakala National Park, expect temperatures in the 40s or lower, so bring warm clothes.
There are generally two seasons in Maui. Winter (November through April), when temperatures typically range in the low-70s to mid-80s, and summer when the high can run into the low-90s. The trade winds keep you comfortable year-round so any time of year is a good time to visit Maui.
