Marine WindsHere’s the latest (automatically updated) weather map showing high pressure systems to the northeast of our islands. Trade wind speeds will be locally strong and gusty through Thursday.

Satellite and Radar Images: To view the cloud conditions we have here in Hawaii, please use the following satellite links, starting off with this 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. Finally, here’s a Looping IR satellite image, making viewable the clouds around the islands 24 hours a day. To help you keep track of where any showers may be around the islands, here’s the latest animated radar image.

Hawaii’s MountainsHere’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 weather conditions.

Tropical Cyclone activity in the eastern and central Pacific – Here’s the latest weather information coming out of the
National Hurricane Center, covering the eastern north Pacific. You can find the latest tropical cyclone information for the central north Pacific (where Hawaii is located) by clicking on this link to the Central Pacific Hurricane Center. Here’s a tracking map covering both the eastern and central Pacific Ocean. A satellite image, which shows the entire ocean area between Hawaii and the Mexican coast…can be found here. Of course, as we know, our hurricane season won’t begin again until June 1st here in the central Pacific.

 Aloha Paragraphs

Blustery trade wind weather pattern



Our local trade winds increased during the day Tuesday, which will remain on the blustery side through Friday…calming down a touch by the weekend. As we glance at this weather map, we find several high pressure systems spread out to our northeast Tuesday night. These high pressure cells have an elongated ridge extending westward, running by our islands to the north. The models suggest that by this weekend into early next week, our local trade winds will be easing up again somewhat. The increased wind speeds now however have triggered a small craft wind advisory in those coastal and channel waters around Maui and the Big Island.  In addition, stronger winds atop the Big Island summits, and now the Haleakala Crater too…have triggered an active wind advisory.

The expected increase in windward showers didn’t happen as expected, despite the presence of a trough of low pressure which recently passed across the island chain. As this IR satellite image shows, we see no lack of low clouds, and some middle level clouds over the Big Island, moving towards Maui County. Although, by shifting over to this looping radar image, despite whatever cloudiness we see, there aren’t many showers falling. There’s still a chance of having some showers, although less so than previously thought. We sure could have used the moisture, although considering that June is the driest month of the year here in the islands…it’s not all that surprising. Interesting enough, the computer models are suggest again, that we might see an increase in windward showers early next week.

It’s Tuesday evening as I begin writing the last section of today’s narrative. The trade winds are strong enough now, that the NWS forecast office is keeping a small craft wind advisory active in the southern part of the island chain. The winds atop the two highest summits on the Big Island, and Maui too, have gotten windy enough, that the NWS has issued a wind advisory up there through Thursday morning. As noted above, the rainfall that we expected seems to be letting us down. ~~~ Wednesday I will be taking off for a week long visit to see my family in Long Beach, California. I’ll fly back to Maui the following Wednesday. I look forward to seeing my Mom and Dad, and my sisters and brother too. ~~~ Looking out the window of my office here in Kihei, Maui this evening, I can see smoke in the air, coming from two wild fires that are burning upslope from the Maalaea Bay. The winds are still strong enough to really be whipping these flames along. Speaking of strong winds,

these are strongest gusts at around 6pm on each of the islands:

Kauai –          32 mph
Oahu –          38
Molokai –       37
Kahoolawe – 44
Maui –            46

Lanai –          00 – blocked from the gusty trade winds
Big Island –   39

Other than the smokey air, and strong and gusty winds here in Maui County, skies are actually quite cloud free. I’ll return early Wednesday morning to sign off for a week, as I go to visit my family. I hope you have a great Tuesday night until then! Aloha, Glenn
