Moderate trades will build back into the region today. A weak trough near the Big Island this morning is producing showers and clouds over the eastern end of the island chain. As this trough weakens and moves westward, expect showers to trend down by tonight. Elsewhere, drier conditions will prevail. Trade winds are anticipated to become breezy by the end of the week as high pressure strengthens north of the state. Slightly wetter trades will be possible this weekend.
Gentle to moderate trades will persist today with localized sea breezes developing over sheltered leeward areas. This should allow for afternoon clouds and a few showers over select leeward areas. Mostly VFR conditions are expected through the day with brief periods of MVFR ceilings and visibilities in the afternoon.
No AIRMET's are in effect.

A fresh, long period northwest swell will build today, pushing surf along north and west facing shores to near seasonal averages through Wednesday. This swell will decline Thursday and Friday. By late Friday, a medium period north- northwest swell will build and once again help bring surf to near seasonal averages through the weekend.
South shore surf will remain elevated through Wednesday as a long period south- southwest swell slowly declines. Another long period south swell will help produce surf near seasonal average Thursday into early this weekend.
Surf along east facing shores will remain small through Thursday as small wind waves and tiny east swell persist. Choppy surf will increase slightly as trade winds strengthen across the region Friday into the weekend.
None.
