Moderate to fresh north to northwest breezes will briefly veer out of the east by early Wednesday and hold through the day as high pressure builds over the state. The pressure gradient will become weak enough to support localized afternoon sea breezes for Kauai and Oahu tomorrow. Moderate to locally fresh south to southwest winds are expected to return over the western end of the state during the second half of the week as the next cold front draws closer. Guidance shows this next front moving into the area late Friday through Saturday with strong- to near gale-force northeast winds filling in behind it late in the weekend through early next week. Ocean conditions will quickly respond and become hazardous due to a combination of winds and seas. In addition to the winds and seas, a wet pattern with locally heavy rainfall and potentially a few storms may accompany this front over the weekend through early next week.

Surf along exposed north- and west-facing shores will remain well above warning levels into Wednesday before gradually lowering to advisory levels by Thursday. Observations at the offshore buoys to the northwest reflect this trend and indicate the swell easing this evening. Heights should lower to advisory levels by Wednesday night and Thursday, then potentially below advisory levels for a brief period Thursday night into Friday. Heights could return to warning levels for exposed coasts Friday night into Saturday due to a fresh northwest swell arriving from a hurricane-force low over the far northwest Pacific.

Surf along east facing shores could quickly rise and become rough this weekend as strong- to near gale-force northeast winds fill in behind a cold front. Heights could near the warning level during the peak by Monday.
