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 Weather Narrative ~~~

 

Glenn’s Wednesday comments:  I’m at home here in upper Kula, Maui, Hawaii

512am, it’s mostly clear here in upper Kula with calm winds, and a low temperature at my place of 53.5 degrees…with the relative humidity 83%

915am, sunny to partly sunny, with low clouds and some high cirrus too…nice summer day!

 

>>> Highest Temperature Tuesday, July 14, 2026 – 115 at Stovepipe Wells, CA
>>> Lowest Temperature Wednesday, July 15, 2026 – 37 degrees at Foxpark, WY

 

Hawaii’s Weather Highlights…as of Wednesday morning:  Moderate trades deliver showers windward and mountains through the weekend. A few afternoon showers are possible as well, for south shores and leeward sections today and Thursday.

Short Term Update:  Morning atmospheric soundings had a bit of a southerly component to the winds, which has veered low cloud motions toward the WNW. The general idea seems to call for showers concentrating over the south shore and leeward Oahu this afternoon into the early evening, thanks to low level convergence from Maui County. Downwind convergence could carry afternoon showers to other islands too. Plenty of subsidence aloft will limit shower intensity, as the upper low NW of Kauai is not having any significant effect on our local stability.

Weather Commentary…as of Wednesday morning: Expect little change for the next several days, as moderate trades deliver showers to the windward and mountains areas into next week. The upper air pattern shows a closed upper low positioned northwest of Kauai, and high pressure ridging established over and east of the remainder of the state.

Brief veering of the wind flow through the lowest 10,000 feet of the atmosphere potentially sets the stage for showers to develop within the leeward Molokai plume, and extends over portions of Leeward Oahu this afternoon into the evening. High stability will limit potential for vertical shower development, and should keep shower intensity in check, but some enhanced coverage of showers compared to normal will be possible.

Marine Conditions…as of Wednesday morning: High pressure far north of the islands will maintain a trade wind pattern, however as the high has weakened and lifted away from the islands, trade winds are not quite as strong. Winds across the coastal waters remain below Small Craft Advisory levels. Winds could rebound Thursday into the weekend as the high sinks southward, tightening the pressure gradient over the islands and bringing Small Craft Advisory winds back to the typical windy waters.

A small bump in the otherwise fading medium-period southwest swell should bring a slight increase in south surf today. The southwest will return to a gradually decline by tonight and continue through the rest of the week. A series of overlapping small south and southwest swells will maintain small south shore surf, with a larger south swell expected early next week.

Surf along east-facing shores will be slightly below seasonal averages through Thursday with lighter trade winds. Surf may then climb back up somewhat as trades strengthen through the weekend.

A series of small, long to medium period west to west-northwest swells generated by former Super Typhoon Bavi will be possible throughout the rest of the week. Otherwise, no significant north or northwest swells are expected.

Northeast Pacific:

Tropical cyclone 05E (Elida)…is located about 570 miles south-southwest of the southern tip of Baja California

ELIDA A LITTLE STRONGER AS IT MOVES OVER THE OPEN EAST PACIFIC

According to the NHC Advisory number 4

Elida is moving toward the west near 15 mph, and this general motion is expected to continue today followed by a gradual turn to the west-northwest and northwest over the next few days. Maximum sustained winds have increased to near 45 mph with higher gusts. Gradual strengthening is forecast over the next day or so followed by a somewhat faster rate of intensification. Elida is forecast to become a hurricane on Friday. Tropical-storm-force winds extend outward up to 90 miles from the center.

>>> Offshore of Southern and Southwestern Mexico:

An area of low pressure is expected to form later this week several hundred miles south of the coast of southern Mexico. Environmental conditions appear conducive for gradual development of this system thereafter, and a tropical depression is likely to form by this weekend into early next week while it moves generally west-northwestward well offshore of Mexico.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…high…80 percent

Central Pacific: There are no active tropical cyclone

>>> Well South-southwest of the Hawaiian Islands:

Invest 91C

A broad area of low pressure located several hundred miles south-southeast of the Hawaiian Islands is producing limited shower and thunderstorm activity. Environmental conditions are becoming less favorable, and its chances for further development are decreasing.

* Formation chance through 48 hours…low…20 percent
* Formation chance through 7 days…low…20 percent

 

>>> Well Southwest of the Hawaiian Islands:

Invest 90C

A trough of low pressure located well southwest of the Hawaiian Islands and several hundred miles south-southeast of Johnston Atoll continues to produce disorganized showers and thunderstorms. Environmental conditions appear conducive for gradual development of the system over the next several days, and it could become a tropical depression by the end of the week while it moves slowly northwestward toward the vicinity of Johnston Atoll.

* Formation chance through 48 hours…medium…50 percent
* Formation chance through 7 days…medium…60 percent

 

>>> Northwest Pacific Ocean:  There are no active tropical cyclones

>>> Southwest Pacific Ocean: There are no active tropical cyclones

>>> North and South Indian Oceans / Arabian Sea: There are no active tropical cyclones

Interesting:  Smoke Season is Back

As Canada heads into the 2026 wildfire season, Canadians should expect smoke-filled skies to become a more regular part of summer, even in communities far removed from active fires.

New insights from the University of Waterloo highlight how wildfire smoke is evolving into a widespread public health concern, with impacts that are harder to predict and increasingly difficult to avoid.

“Wildfires have historically been a major driver of harmful air pollution in Canada. Under climate change, that influence is expected to grow,” says Dr. Rebecca Saari, an Associate Professor of civil and environmental engineering at Waterloo and Tier 2 Canada Research Chair in Global Change, Atmosphere and Health. “Other work shows in recent years that wildfire smoke has caused annual health damages ranging from around half a billion to over $6 billion dollars a year.”
