Hawaii’s Mountains – Here’s a link to the live web cam on the summit of near 13,800 foot Mauna Kea on the Big Island of Hawaii. This web cam is available during the daylight hours here in the islands…and when there’s a big moon shining down during the night at times. Plus, during the nights you will be able to see stars, and the sunrise and sunset too… depending upon weather conditions.
Aloha Paragraphs
Low pressure system north of the state, with its cold front
just northwest of Kauai — to see a cold front so close to
Hawaii during the summer months…is extremely rare!
Mostly clear with clouds over some parts of the state…with
the fragmenting out of season cold front close to Kauai,
and high cirrus to the southwest – Looping version
Some showers…mostly over the nearby ocean, a few
quite generous over the ocean to the southwest of
Maui County – looping radar image
~~~ Hawaii Weather Narrative ~~~
The just past July Full Moon…will still be
very bright tonight!
Our local winds will remain lighter than normal into Friday…and then gradually head back towards normal through the holiday weekend into next week . Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a real-time wind profiler of the central Pacific. We find moderately strong high pressure systems far to the northwest and northeast of the state. At the same time, there’s a low pressure system to the north, along with its fragmenting cold front near Kauai. Our winds will remain on the softer side of normal, with onshore daytime sea breezes, and offshore flowing land breezes during the night. This unusual weather situation is being caused by the relatively close proximity of the low pressure system, and its cold front, which is pushing high pressure ridges close to the state. We should see slowly rebounding trade winds going into the weekend…remaining well established through next week. As a matter of fact, they may become stronger and gusty, as a low pressure system might move by to the south of Hawaii during the middle of next week.
We’ll see showers over the islands during the afternoon hours…locally. As the winds remain rather soft for the time being, we’ll see a convective weather pattern continuing. This will bring afternoon upcountry clouds leading to localized showers, clearing back during the nights for the most part. As the trade winds gradually return into the weekend and beyond, there will be the usual off and on passing windward biased showers. There’s the chance that the northern fringe of a tropical system may bring an increase in showers during the middle of next week. As a matter of fact, some of the computer models are suggesting rain arriving over some parts of the state next Wednesday continuing into Friday. I’ll be keeping an eye on this potential weather incident…stay tuned. I’ll also be back with more updates on all of the above, I hope you have a great Thursday night wherever you’re spending it! Aloha for now…Glenn.
A new tropical disturbance is active in the eastern Pacific…and may cross over into our central Pacific before too long. This area of disturbed weather is being referred to as Invest 95E. I am not concerned about this becoming a problem for the Hawaiian Islands, although thought you’d want to know about it anyway. Here’s a satellite image of this area, along with the looping version. Here’s what the global hurricane models are showing, in addition to another view with the GEPS model…showing the Hawaiian Islands in the picture. This satellite image, shows that this area has a low 30% chance of developing into a tropical depression over the next two days, increasing to a medium 60% chance over the next five days. The other yellow X towards Mexico is another area of disturbed weather, which has a low 0% chance of developing over the next two days…increasing to 30% within five days. By the way, here’s what the National Hurricane Center suggests will be happening in 5-days.
Here on Maui…it’s 535am Thursday morning, with mostly clear skies, and still light to almost medium thick volcanic haze (vog) over the island as well. The air temperature here in Kula, at my upcountry weather tower was 55.9 degrees, while it was 72 down at the Kahului airport, 77 out in Hana…and 46 up at the summit of the Haleakala Crater at near the same time. / Now at 1030am, it’s clouding up rather quickly, at least up here on the mountain. Looking down into the central valley, it looks like the volcanic haze level is now up to medium thick…at least.
– We’re into the mid-afternoon now, under partly to mostly cloudy skies, along with rather thick volcanic haze. There’s been a few flecks of moisture falling, falling short of even being called a mist though. While the temperature hit 93 today down in Kahului, breaking the all time high temperature record for today…it has remained in the middle 70’s upcountry here in Kula. I much prefer these cooler temperatures, although the vog situation is getting a little out of hand. It’s so unusual to have volcanic haze in the summer, when the trade winds should be briskly blowing!
– It’s fun to highlight the unusual weather features that are occurring across our area now. In sum, we have a cold front just 100 miles northwest of Kauai, we have Kona winds blowing across most of the state, we have thick vog over Maui County and other parts of the state, and we have a rising northwest swell. These would all fit well into the winter season, say January or February, although, now that we’re into the July month of summer, all I can say is…this is crazy! Well, I shouldn’t forget to add that the high temperature was a record breaking 93 degrees today in Kahului…so it’s not all like winter after all. I’m totally fascinated, and wonder what else will be different through the rest of this year, in terms of what this very strong El Nino condition will do for us here in Hawaii…and across the rest of the world too!

Interesting: Extremely high coastal erosion in northern Alaska – In a new study published today, scientists from the U.S. Geological Survey found that the remote northern Alaska coast has some of the highest shoreline erosion rates in the world.Analyzing over half a century of shoreline change data, scientists found the pattern is extremely variable with most of the coast retreating at rates of more than 1 meter a year.
“Coastal erosion along the Arctic coast of Alaska is threatening Native Alaskan villages, sensitive ecosystems, energy and defense related infrastructure, and large tracts of Native Alaskan, State, and Federally managed land,” said Suzette Kimball, acting director of the USGS.
Scientists studied more than 1600 kilometers of the Alaskan coast between the U.S. Canadian border and Icy Cape and found the average rate of shoreline change, taking into account beaches that are both eroding and expanding, was -1.4 meters per year. Of those beaches eroding, the most extreme case exceeded 18.6 meters per year.
“This report provides invaluable objective data to help native communities, scientists and land managers understand natural changes and human impacts on the Alaskan coast,” said Ann Gibbs, USGS Geologist and lead author of the new report.
Coastlines change in response to a variety of factors, including changes in the amount of available sediment, storm impacts, sea-level rise and human activities. How much a coast erodes or expands in any given location is due to some combination of these factors, which vary from place to place.
“There is increasing need for this kind of comprehensive assessment in all coastal environments to guide managed response to sea-level rise and storm impacts,” said Dr. Bruce Richmond of the USGS. “It is very difficult to predict what may happen in the future without a solid understanding of what has happened in the past. Comprehensive regional studies such as this are an important tool to better understand coastal change. ”
Compared to other coastal areas of the U.S., where four or more historical shoreline data sets are available, generally back to the mid-1800s, shoreline data for the coast of Alaska are limited. The researchers used two historical data sources, from the 1940s and 2000s, such as maps and aerial photographs, as well as modern data like lidar, or “light detection and ranging,” to measure shoreline change at more than 26,567 locations.
Thomas Says:
Glenn, maybe you know off the top of your head what the all time highs are for Kahului and the entire state of Hawaii? Hi Tom, Kahului was 96 I believe, and there was once a 100 degree high down on the Big Island of Hawaii. Good question, thanks. Aloha, Glenn
Susan Says:
Ok Glenn, I accept your offer! Here is another question. There is a wind chill factor …. Has anyone factored in a vog index equivalent of wind chill meaning that …..when the temperature is 80 in Kona but there is heavy vog it feels like 85. I went to Waimea yesterday to cool off and there was no cooling the temp was 84 late afternoon! Two more days I imagine until things break and trades are back …Aloha, Susan ~~~ Hi Susan, another good question, there should be a vog index equivalent…shouldn’t there! By the way, I can’t imagine its any more voggy down on the Big Island…as it is here on Maui right now! Thick vog, the Kahului AP hit 93 this afternoon, which passed the prior record of 91 for the date…by two degrees! The trade winds will slowly return this weekend, and then pick up next week. Aloha, Glenn

Glenn—http://www.solarimpulse.com (http://www.solarimpulse.com/leg-8-from-Nagoya-to-Hawaii)
gets you to their main web
page, which includes live a feed, conversations, live updates every few hours, and a cam on the pilot, Andre, who will have flown some 120 hours straight by Oahu. Thanks –Rich ~~~ Hi Rich, I’ll put this out there for everyone to see, and those interested can follow along! Aloha, Glenn
Mr. rich Says:
Come on, Glenn–Let’s get with the SOLARIMPULSE’s arrival program! The solar-power plane is 12hrs. from Oahu, and needing to pass over that “extremely rare” cold front, NW of Kauai. Help us see what they are going to be dealing with as they pass over it (at just 30 knots per hour)>
Big Media is barely covering this historic air journey!
Aloha, Rich — Hi Rich, thanks for your prompting, and rightly so. I’ve got my hands so full dealing with the weather here in Hawaii, and for those storms all around the world too. Send me a link for information, and I’ll post it here. Aloha, Glenn
Susan Says:
Hi Again Glenn! Are there ever “maximum” minimum temperature records? 74 for Hilo sounds like a very high minimum temperature for a windward location. And 79 for Kona? Is that common for summer? Aloha from across the A channel. Susan ~~~ Hi Susan, yes there are maximum minimum temperatures…good question. As a matter of fact, the low for Kona this morning was 80! No not common, although I have seen this before in previous years. Keep your good questions coming from down there on the Big Island. Aloha, Glenn
