Hazy Skies Today, Front Expected For Weekend
A Marine Weather Statement has been issued by the National Weather Service for a very large west-northwest swell. The Weather Service in Honolulu says the very large swell will remain elevated into Thursday. They are warning of strong harbor surges and large breaking waves at harbor entrances exposed to the swell. One location that could expect such conditions is Honokohau harbor.
A High Surf Warning has been issued for the west side of the Big Island. The warning is posted through Friday at 6:00 p.m. Wave heights of 15 to 20 foot faces are expected. Expect ocean water occasionally sweeping across portions of beaches, very strong breaking waves and strong longshore and rip currents. Breaking waves may occasionally impact harbors making navigating the harbor channel difficult. Large breaking surf, significant shore break and dangerous currents will make entering the water very hazardous. Boaters should be aware of an increased number of surfers in the water.
A Small Craft Advisory has been issued for all island waters through 6:00 p.m. Friday for southwest winds from 10 to 20 knots and rough seas of 7 to 16 feet.

Today, Thursday, January 22, 2015
Partly cloudy skies are expected today. Variable winds up to 15 mph are forecasted. There is a southerly component to the wind so haze could spread over onto the Hilo side of the island as well today (see UHSOEST vog model above). Afternoon sea breezes are expected to bring cloud cover and possible showers to the leeward side. High temperatures should fall in the range of 80° to 85°.

Partly cloudy skies are expected. Windward spots can expect isolated showers in the evening with scattered showers after midnight. Leeward areas should become mostly clear after the land breeze takes hold. Variable winds up to 15 mph are expected. Low temperatures are forecasted from 67° to 72° degrees.

Winds will turn to the south and southwest and become stronger on Thursday as a front approaches the islands from the northwest. The front will bring increasing showers, starting over Kauai county on Friday and spread down the island chain through the weekend. High pressure will bring a dry trade wind regime in the wake of the front on Sunday and into early next week. Large surf from a northwest swell will also continue through the weekend.
