Weather Chart – Here’s the latest (automatically updated) weather map…showing a 1031 millibar high pressure system far to the NE of Hawaii. There will be light to moderately strong trade winds Tuesday….becoming northerlies behind a cold front Wednesday on Kauai, and Wednesday night for Maui. Here’s a Weather Map Symbol page for clarification about what all those weather symbols mean on the map.
Hawaii’s Mountains – Here’s a link to the live webcam on the summit of near 14,000 foot Mauna Kea on the Big Island of Hawaii. The tallest peak on the island of Maui is the Haleakala Crater, which is near 10,000 feet in elevation. These two webcams are available during the daylight hours here in the islands…and when there’s a big moon rising just after sunset for an hour or two! Plus, during the nights and early mornings you will be able to see stars, and the sunrise too…depending upon cloud conditions.
Satellite Images – To view the cloud conditions we have here in Hawaii, please use the following satellite links, starting off with the Infrared Satellite Image of the islands to see all the clouds around the state during the day and night. This next image is one that gives close images of the islands only during the daytime hours, and is referred to as a Close-up visible image. This next image shows a larger view of the Pacific…giving perspective to the wider ranging cloud patterns in the Pacific Ocean…out from the islands. To help you keep track of where any showers may be around the islands, here’s the latest animated radar image.
Tropical Cyclone Activity – The eastern Pacific hurricane season runs from May 15 through November 30…while the central Pacific (where Hawaii is) runs from June 1 through November 30. The latest storm information for the eastern Pacific can be found by clicking here. A storm tracking map for both the central and eastern areas can be found by clicking here. For the central Pacific, the latest storm information can be found by clicking here.

The upper level trough of low pressure, which brought localized heavy showers to some parts of the state Sunday evening into the night…is moving away now. In its place we’ll see the return of light trade winds. The absence of the destabilizing presence of the upper trough, will allow fine weather to persist through Tuesday. Days will be sunny to partly cloudy for the most part, with just a few showers falling along the windward coasts and slopes. The leeward sides will enjoy warm sunshine during the days, and seasonable temperatures at night.
The latest weather maps and satellite images show a cold front approaching our islands from the NW direction. This cold front is expected to arrive Tuesday night over the Kauai end of the state, where we’ll see an increase in showers. During the day Wednesday it will progress down through the island chain past Oahu to Maui County. It may stall there, or could move down over the Big Island during the night into Thursday morning? The bulk of the associated showers will dampen the windward sides, but just about everywhere will likely get some moisture from the frontal passage.
Islanders will get their first taste of pre-winter chill in the wake of the cold front. Winds following the frontal cloud band will arrive from the north to NNE directions. An air flow such as this brings dry and cool air into the Aloha state. Daytime temperatures will take a "tumble" (tropically speaking) for a couple of days, with folks reaching for that extra blanket during the nights. Thereafter, the breezes will shift slightly to the NE, which will continue to bring dry air and slightly cooler air than usual into our area…with a few windward showers falling in a misty form. Towards the weekend a new trough of low pressure may arrive, although its a bit too early to know exactly what influence it will have yet.
It’s early Monday evening here in Kula, Maui, as I begin writing today’s sunset commentary. It was a sunny day for the most part, with some areas seeing a bit of cloudiness at times. Showers were few and far between, which was good for beach goers. Tuesday will remain nice, although as noted in the paragraphs above, weather conditions will change notably by mid-week…as a showery and cool air carrying cold front noses into the Aloha state. The sunsets are happening so early now, everywhere in the northern hemisphere, from the equator all the way up to the north pole. The longer nights are of course allowing more radiational cooling, so that minimum temperatures are getting cooler, even down here in the tropics. Nothing too drastic yet, but more and more the nights, even at sea level are dipping down below the "warm threshold" of 70F degrees. The days continue to warm up nicely, reaching into the low to middle 80F’s in general near the ocean. I hope you have a good Monday night. I’ll be back very early Tuesday morning, with more news about the approaching cold front to our NW. Aloha for now…Glenn.
