Here’s the webcam for the Haleakala Crater on Maui. These webcams are available during the daylight hours here in the islands, and at night whenever there’s a big moon shining down. Also, at night you will be able to see the stars — and the sunrise and sunset too — depending upon weather conditions.

~~~ Hawaii Weather Narrative ~~~

Small Craft Advisory…coastal and channel waters around Kauai, windward Oahu, and around the windiest waters around Maui County and the Big Island

High Surf Advisory…east shores of Kauai, Oahu, Molokai, Maui, and the Big Island 

High Wind Warning…Big Island summits / 55 to 65 with gusts to over 70 mph

Broad Brush Overview: The current episode of brisk trade winds will prevail through the week into next week, carrying off and on clouds and showers…which will favor windward areas. Cooler and drier air moving in from the northeast will keep temperatures lower than normal over the next several days. Fewer showers are expected this weekend, although wet and windy weather will likely return next week Tuesday and Wednesday.

Details: A strong high pressure system well to our north, will dominate weather conditions across the state. Satellite images show a cloud banks along the windward slopes and eastern offshore waters of Maui and the Big Island. High cirrus clouds will move from west to east across the islands at times. Northeast winds will bring cool and dry air across the islands…prompting cooler than normal high and low temperatures.

Looking Ahead:  A bit of uncertainty remains in the forecast next week, as a strong upper level trough moves into our area next Tuesday and Wednesday. This trough may turn out to be strong enough to pull up deep tropical moisture over the state then. This in turn may bring an increase in showers, and possibly even a few thunderstorms. The models have shown this wet and windy trend for the past three days…stay tuned for any adjustments.

The current swell should peak tonight, and then be on the decline tonight. Another rise will occur Thursday, and persist into the weekend. A High Surf Advisory remains posted for various north and east facing shores through Thursday…although will likely be extended.

This swell could also produce moderate to strong surges in harbors exposed to the north, primarily in Kahului and Hilo harbors.

In addition, a moderate west-northwest swell is expected to persist, although surf is expected to remain below the advisory level for west facing shores. Small southerly swells will continue for the time being.
