Hawaii’s Mountains – Here’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii. Here’s the webcam for the (~10,023 feet high) Haleakala Crater on Maui (out of operation). 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’s Weather Highlights…as of Sunday evening: High pressure far northeast will drive trade winds today. Wind speeds will taper off through much of this coming week, as the remnant of former Tropical Cyclone Genevieve linger between the high and Hawaii. Clouds and showers will favor windward and mountain areas, with some enhancement possible for the western half of the state Tuesday through Thursday, due to an upper trough setting up to the west.

Weather Narrative..as of Sunday evening: A 1032 millibar high centered far northeast of Hawaii, will generate breezy trade winds today. Winds will carry in scattered low clouds and showers, focusing across windward slopes. Wind speeds will decline to gentle to moderate through much of the new week, as remnants of Tropical Cyclone Genevieve linger between Hawaii and the high pressure system.

Genevieve is now a post-tropical cyclone. It is not expected to impact Hawaii, aside from the decrease in wind speeds here in the islands. Model guidance continues to show an upper level trough near the western end of the state Tuesday through Thursday, which may provide some enhancement of incoming trade wind clouds and showers over the western half of the state. This feature will move north away from the area on Friday.

Fire Weather…High pressure far northeast will drive trade winds tonight. Wind speeds will taper off through much of this week as remnants of Tropical Cyclone Genevieve linger between the high and Hawaii. Clouds and showers will favor windward and mountain areas, with some enhancement possible for the western half Tuesday through Thursday due to an upper trough setting up to the west. Inversion over Hawaii will be between 6,000 and 7,000 feet.

Marine Conditions…as of Sunday evening: A high pressure system north of the Hawaiian Islands will weaken over the next few days, decreasing trade wind speeds from moderate to strong range, into the gentle to fresh range from Monday through Thursday. The Small Craft Advisory (SCA) coverage was lowered to the typical windier waters and channels near Maui and the Big Island. Winds are expected to decrease below SCA thresholds by Monday.

Surf along south facing shores will stay below seasonal averages, with mainly background energy throughout most of the new week. The next small, long period south swell will arrive by next Saturday, with a slight rise in south shore surf heights through next Sunday. Possibly a larger long period south swell arriving early the following week.

East facing shores will remain rough and choppy, due to a combination of strong trade wind waves and a small, medium period easterly swell generated from post-Tropical Cyclone Genevieve that will linger for next few days.

Surf along north facing and west shores will remain flat to tiny, except for areas exposed to the easterly trade wrap.
