Detailed Forecast

Synopsis

Light to moderate trade winds today will diminish Friday and Saturday with afternoon sea breezes and nighttime land breezes expected. Showers will be limited with clouds increasing in the afternoon hours. Trade wind weather returns Sunday and continues into next week with showers favoring windward and mountain areas.

Discussion

Overnight satellite and radar imagery showed overcast clouds and showers moving into windward areas of Maui and the Big Island, while other windward locations are experiencing passing showers. This trend will continue into the morning hours before partial clearing in the late morning and early afternoon. Leeward locations on the smaller islands may see a stray shower through the early morning hours. A ridge about 200 miles north of Kauai will allow light to moderate trade winds to hold today with protected leeward locations seeing sea breezes and cloud buildups in the afternoon. The ridge will move slowly SE through the day and winds will weaken and turn out of the southeast later tonight. With light southeastly flow expected Friday and Saturday, most island will see a nighttime land breeze and daytime sea breeze regime with increasing afternoon clouds and limited showers over interior sections. Substantial warming aloft with keep the atmosphere stable and showers will be limited in coverage and intensity. The ridge will retreat to the north Sunday and next week, allowing trade winds to return.

Aviation

A weak ridge north of the state will move south slowly today and lighten the winds, which will allow for sea breezes to develop in many areas west of the Big Island. Clouds, and possibly some light showers, will tend to form in the afternoon hours over leeward, interior, and/or mauka sections as sea breezes take hold. Land breezes will develop as the land cools overnight and cloudiness dissipates. VFR conditions will predominate.
No AIRMETs are in effect nor expected through the day.

Marine

A stalled front north of the region will keep a weak ridge in place northeast of the island chain through Saturday. This ridge will build in north of the islands from Sunday onward. Light to moderate trades will prevail through Saturday, then strengthen to moderate to breezy levels from Sunday through the middle of next week. Small Craft Advisories may be needed for the windier waters around Maui and the Big Island during this time period.
Surf along south facing shores will see a series of south swells over the next week. These swells should produce surf heights near the summertime average heights (5 ft) through the middle of next week. The current tiny northwest swell will diminish today, before a new northwest swell builds in from Friday into early Sunday. Surf along east facing shores will remain small due to weak trade winds over and upstream of the island chain.
