Weather in Maui Hawaii
There are a number of different microclimates that make up the Maui weather throughout the various regions of the islands. While the leeward (western) side of the island is typically a drier area, the windward (eastern) side sees more rain.
The leeward side sees the Maui weather that makes for the best beaches and resorts of Wailea, Kihei, Lahaina, Kaanapali, and Kapalua. On the other side, the windward side, there is the Iao Valley and the long, winding road to Hana that takes you through the exotic and gorgeous rainforests.
The coastal areas experience warmer Maui weather than the Upcountry Maui region. The temperatures there are generally 8 to 10 degrees Fahrenheit higher along the coast than they are further inland. That said, if you head up to Haleakala National Park, where the Haleakala Visitor Center is located 9,740 feet up, then you will discover that the temperatures will generally be in the range of the low 40s, or even cooler. This makes it very important for you to bring warm clothing with you if you intend to travel to that part of the island.
The Maui weather is generally made up of two main season. They are winter, which includes the months of November through April, and summer, from May through October. The temperatures in the winter will generally range from the low 70s to the mid 80s, depending on where you are on the island. In the summer, it is warmer, with temperatures rising as high as the low 90s.
That said, the region experiences trade winds all year long, so they help to keep the temperature moderate no matter when you happen to be visiting the island. Most people who visit the island find that even on the hottest days, they don’t find it overwhelming because the breeze is always there to cool you down. Unless you head to the higher altitudes, the temperatures are relatively comfortable and consistent.
That said, the windward (east) side of the island does experience relatively heavy rainfall (thus the rainforest), so if you plan to spend any time in that area, make sure to bring some waterproof clothing along with you so that you can stay dry until the clouds move along. The leeward side is much sunnier and dryer Maui weather, so you won’t have as much need for wet weather gear while you’re visiting that side of the island.
