Trade winds are strong right now, with high surf hitting the south shore today. Windward areas are seeing frequent showers through the weekend.

South-facing beaches have dangerous surf today through Sunday—stay out of the water unless you're an experienced swimmer. East-facing shores will build rough water by Sunday or Monday. The bigger picture is a tropical system, Fausto, heading our way. It's weakening but should arrive near the islands by Tuesday or Wednesday as a tropical storm or weaker system, bringing strong winds, rough seas, and heavy rain. The exact track is still uncertain, so check the forecast daily.

Get your beach time and water activities in today through early next week on the leeward side, where conditions stay calmer. Be ready to shift plans by midweek when conditions turn rough.

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

Hawaii stays between 75–85°F year-round at sea level. 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.

Island Weather Guides

Each island has its own microclimate personality. These guides cover precipitation maps, monthly climate data, and region-by-region breakdowns to help you pick the right area to stay.
