A northwest swell will continue to decline through Saturday. However, another large northwest swell is expected to arrive overnight, then peak Sunday night. Surf will potentially top out near warning levels along north and west facing shores. Another more moderate northwest swell is expected to arrive overnight Monday. A much smaller northwest swell should then arrive overnight Wednesday. Trade winds are expected to ramp up further from Sunday to Tuesday, and a Gale Watch remains in effect for this time period for the typical windy zones around Maui and the Big Island due to the wind acceleration around the islands. The winds, combined with an easterly swell, will boost surf to advisory level along east facing shores by Sunday and continue through at least Tuesday.

Weather Outlook for Saturday

Trade winds will strengthen, reaching windy levels Christmas Day through Tuesday, as a strong high pressure system slowly passes north of the area. Clouds and showers will favor windward and mauka areas, particularly during the night and early morning hours, with showers reaching leeward areas from time to time as well. A front may approach the state from the north next Thursday night or Friday.

A 1030 mb surface high about 1250 miles northeast of Hawaii continues to drive moderate to locally strong trade winds across the state. Satellite imagery and radar show a band of clouds and showers moving west of the islands this morning while an area of showery low clouds begins to move across the Big Island and Maui County. These clouds and showers will likely reach Oahu within the next few hours. Except on Oahu, which temporarily has clearer skies, windward slopes are mostly cloudy. Partly cloudy skies are noted over most leeward areas. Overnight soundings show a rather dry atmosphere with precipitable water values in the 1.2 to 1.4 inch range. Mild instability is noted, which is sufficient to support the misty showers recorded overnight.

Models show a front about 400 miles to the northwest of Kauai will stall and weaken, while a strong high builds in behind it. This high will strengthen trade winds today and tonight, with speeds reaching windy levels Sunday through Tuesday. A Wind Advisory will likely go into effect for at least portions of the state during the Sunday to Tuesday period. Any areas not in the advisory are still likely to be breezy. Trade winds will focus any rain tracking in with the trade winds over windward and mauka areas through the next several days. However, with the atmosphere expected to remain rather dry and stable, rainfall amounts will be light. Strong trades could carry some of the light showers over to leeward sides of the smaller islands at times.

A cold front will come in the north and northwest around Thursday night or Friday, causing the trades to ease a bit. Wetter weather could be in store for the second half of the week, but there are subtle model differences. The trades would focus the increase in clouds and showers across windward and mauka areas.
