Mostly dry this morning with light to moderate trade winds, a few showers over windward and mountain slopes. Winds weaken and turn south tonight into Wednesday as a low-pressure system develops north of the islands, starting a wet stretch.
Wednesday afternoon through Friday, rain increases across the island, heaviest on south-facing slopes and coasts. Isolated thunderstorms are possible Wednesday night into Thursday. Rain timing and intensity depend on where the rainband sets up. No flood watch is in place yet, but conditions will be wet. Saturday and Sunday clear out as normal trade winds return.
Beach and water activities work best today and early Wednesday; plan indoor time for Wednesday through Friday as rain increases. Save hiking and summit drives for the weekend.

Microclimate Conditions
Hawaii's mountains create dramatically different weather over short distances. Compare two representative visitor areas on the selected island; each card is a specific local point, not an islandwide reading.

What to Expect
Temperature
Average daytime temperatures at sea level are about 78°F in winter and 85°F in summer. Higher elevations (Haleakala, Mauna Kea) average about a 3.5°F drop per 1,000 feet. Summit temps can hit freezing in winter.
Rain Patterns
Rain is hyperlocal. It can pour in one valley while the beach a mile away stays dry. Windward slopes are generally much wetter than leeward coasts, but the difference varies sharply by island and elevation. Most showers are brief.
Trade Winds
Hawaii's prevailing northeast trade winds help keep the air comfortable. When trades die ("Kona weather"), humidity rises and skies can get hazy. Trades are generally strongest in summer.
Wet vs. Dry Season
November through April is generally wetter (with bigger surf on north shores), while May through October is generally drier. Both seasons are warm enough for the beach. With a strengthening El Niño in place for winter 2026–27, expect a drier-than-usual wet season — see our El Niño winter guide.
