Maui residents and visitors can expect a classic summer day on Saturday, August 1, 2026, with a mix of sunshine, trade winds, and passing clouds. The latest forecast from Maui Now highlights the island's typical microclimates, offering a clear picture of what to expect from leeward shores to the slopes of Haleakalā. Here’s your quick guide to the day’s conditions, along with some practical tips to make the most of the beautiful weather.

Morning Conditions: Trade Winds and Partly Cloudy Skies

The day kicks off with gentle to moderate trade winds flowing from the northeast, keeping temperatures comfortable in the mid-70s to low 80s across most coastal areas. Early risers on the windward side may see scattered showers, especially along the Hana Highway and upcountry regions, but these should dissipate by mid-morning.

By 10 a.m., the sun will break through the clouds in most leeward spots like Kihei, Wailea, and Lahaina, with humidity levels staying moderate. The National Weather Service has not issued any advisories, but boaters and surfers should note that the trade wind swell will produce choppy seas on north and east facing shores.

UV Index and Heat Safety

With summer in full swing, the UV index is expected to reach “very high” levels by noon. Sun protection is a must – opt for reef-safe sunscreen, a wide-brimmed hat, and sunglasses, especially if you plan to spend extended time outdoors. Heat index values may feel like the mid-80s in sheltered areas, so stay hydrated.

Afternoon Outlook: Breezy and Bright

As the afternoon progresses, trade winds will pick up slightly, gusting to 20–25 mph in exposed areas like the Maui Veterans Highway and the slopes of Haleakalā. This breeze will keep temperatures from skyrocketing, with highs peaking around 86°F (30°C) in Kihei and 84°F (29°C) in Kahului. Clouds will increase over the interior valleys, but rain chances remain low for most leeward communities.

If you’re heading to the beach, expect cleaner surf on south and west shores, where the wind is less impactful. Snorkeling conditions should be good at Molokini and Turtle Town early, but the afternoon chop may reduce visibility. For hikers, the Iao Valley and Waihee Ridge trails offer cooler, partly cloudy conditions, but be prepared for mud in shaded sections.

Evening and Night: Clearing Skies

Sunset is at 6:58 PM HST, and the evening will bring a pleasant drop in temperatures, settling into the mid-70s by 9 p.m. Clouds will thin out, leaving mostly clear skies – perfect for stargazing from higher elevations. Overnight lows will dip to the upper 60s in upcountry areas like Kula and Pukalani, so a light jacket is recommended.

What to Expect by Region

  • South Maui (Kihei, Wailea, Makena): Sunny, hot, and breezy. Highs near 86°F, with light showers unlikely.
  • West Maui (Lahaina, Kaanapali, Kapalua): Mostly sunny with passing clouds. Trade winds moderate, surf small but rideable.
  • Central Maui (Kahului, Wailuku): Warmer, with occasional clouds and a 20% chance of a brief shower in the afternoon.
  • Upcountry (Kula, Makawao): Cooler, with highs around 75°F, and a few passing showers possible.
  • East Maui (Hana, Keanae): Cloudy with periods of rain, especially in the morning. Rain gear recommended.

These regional variations are typical for this time of year, driven by the trade winds that funnel moisture into windward slopes while keeping leeward areas dry.
