The National Weather Service forecasts typical October weather for Hawaii on October 31, 2026. Conditions across the islands will feature light trade winds and temperatures reaching into the 70s.

Why it matters

Understanding the holiday weather outlook helps residents plan outdoor events and activities across the islands. Stable conditions are expected to hold through the weekend before a weather front arrives early next week.

Meteorologists forecast temperatures in the 70s with relative humidity between 60% and 70% for Halloween. While trade winds remain the dominant pattern, they are expected to weaken slightly on the holiday.

The players

National Weather Service

The federal agency responsible for providing weather forecasts, warnings, and meteorological data for the United States.

The details

Scattered showers are anticipated to focus primarily on windward and upslope mauka areas, with the highest rain chances occurring over windward exposures. A weather front is expected to pass across the state from the north shortly after the holiday, bringing cooler and drier conditions.

Seasonal Patterns

This forecast follows the National Weather Service's routine meteorological assessment protocols for predicting island atmospheric behavior. The expected conditions reflect standard seasonal stability in Hawaii before the arrival of a transitionary front.

Those planning outdoor Halloween activities should prepare for potential scattered showers, particularly in windward and upslope areas. Residents should monitor local updates as a new weather front is expected to impact the state early next week.

The takeaway

Halloween revelers should enjoy the calm winds and moderate temperatures while preparing for the shift toward cooler weather next week. Planning for intermittent showers in windward zones will ensure outdoor celebrations remain unaffected.
