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. 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 Sunday comments:  I’m with my friend Bob here at our vacation rental at Sea Ranch, Sonoma County CA on a working vacation.

436am HST, it’s clear with high cirrus at Sea Ranch, the low temperature was 44.5 degrees…with calm winds

812am HST, it’s a nice sunny day here at Sea Ranch, so we’re heading over to the Pickleball courts to see if we can get into playing with the local folks here.

1018am, there were several really nice people playing on the three courts, and luckily as soon as I walked up, they had three lovely ladies waiting to play. The weather was rather warm and sunny, so I ended up playing only three games, which seemed fine.

124pm HST, it’s sunny although with increasing high clouds here in Sonoma County. The large waves are rising, and with the light offshore winds, there’s spray coming off the backs of the breaking waves…called spin drift.

 

Interesting Weather Blog: Mauka Showers…El Niño Rainfall Totals in Hawaii from Recent History

 

Hawaii’s Weather Highlights…as of Sunday afternoon: A ridge to the north and Tropical Storm Pena passing far to the south, will maintain a breezy and gusty trade wind pattern over the islands today. Trades will ease briefly during the first half of the week to more typically speeds, before picking back up during the second half of the week, as a strong high pressure system settles north of the state. Pockets of moisture riding in on the trades will focus showers over the windward and mauka areas through mid-week. A band of moisture may move through the state from the north during the second half of the week.

Short Term Update: Breezy trades are bringing in isolated showers to mainly windward and mauka sites. Winds are averaging 10-20 mph with the normal windy sites gusting over 30 mph. These conditions are expected to continue through the afternoon.

Weather Narrative…as of Sunday afternoon: Tropical Storm Pena continues to pass several hundred miles south of the state as a ridge of high pressure remains to the north, generating breezy and gusty trade winds statewide. Satellite and radar imagery show low level bands of clouds with embedded light to moderate showers, focusing mainly along windward and mauka areas, with a few showers spilling over to leeward areas of Oahu and Maui County.

Rainfall totals for the past 6 hours were highest for windward Big Island with totals ranging between 0.30 to 0.80 inches of rainfall. Notably, Kona received nearly 3 inches of rainfall from a small area of briefly moderate to heavy rainfall, but has since dissipated. Rainfall totals elsewhere were modest.

Showers should trend down during the day today before picking backup tonight. Winds will remain breezy and gusty as Tropical Storm Pena tracks westward, and the ridge of high pressure remains nearly stationary. Forecast calls for winds easing briefly to more typical trade wind speeds Monday and Tuesday, as TS Pena shifts far southwest of the state and the ridge to the north weakens. Mid to upper level ridging will generate fairly stable trade wind pattern limiting pockets of showers to windward and mauka areas, particularly during the overnight and early morning hours.

Winds will strengthen again across the state Wednesday as a strong surface high builds north of the islands. During the second half of the week, a cold front may push a band of moisture from north to south across the state, contributing to the increase in showers followed by gusty winds. There is general agreement with the GFS and ECMWF models with the front reaching the islands Thursday, but differences with regards to the amount of shower activity to accompanying the front and the strength of winds.

Fire Weather: Breezy trade winds continue through today, with some weakening Monday and Tuesday. A new ridge building north of the state mid-week will boost trade winds again across the state. Upper and mid level ridging will keep a drier and more stable airmass in place for the next several days, decreasing humidity levels. Fire weather conditions will remain below critical thresholds through much of the week. Temperature inversion heights are expected to remain between 6,000 to 7,500 feet near Big Island.

Marine Conditions…as of Sunday afternoon: Fresh to strong trade winds will prevail through the remainder of this weekend, as high pressure remains in place north of the state, and as Tropical Storm Pena continues to move westward, passing several hundred miles south of the Big Island. A Small Craft Advisory (SCA) remains in effect through tonight for most Hawaiian Waters, due to a combination of winds and elevated seas.

Winds are expected to ease slightly late Monday and Tuesday as the ridge to our north erodes and Pena moves away to the southwest. The SCA will likely be trimmed back to the typical windy waters around Big Island and Maui at that time. Trade winds are then expected to strengthen again on Wednesday as a new high builds to the north. A surface trough will move into the region on Thursday from the north, bringing unsettled clouds and showers across the coastal waters.

A medium period swell out of the north-northwest (325 to 340 degree) continues to build into Hawaiian waters. This swell will peak through the morning hours, increasing surf heights just below advisory levels. The swell will gradually decrease from tonight into Monday, before another small to moderate swell fills in Monday night, keeping small to moderate surf in place through Tuesday. A large northwest to north-northwest swell is then forecast to arrive late Wednesday into Thursday, and could bring surf near or right at warning levels.

A small south-southwest swell will keep surf around the average today before declining Monday through the remainder of the week.

Rough surf along east-facing shores will hold at or above seasonal average through this weekend. Surf will decrease slightly by early next week as trades begin to ease before increasing again by Wednesday.

Atlantic Ocean: There are no active tropical cyclone

Caribbean Sea: There are no active tropical cyclones:

Gulf of America: There are no active tropical cyclones

 

Northeast Pacific: There are no active tropical cyclones

>>> Eastern East Pacific:

An area of low pressure located just offshore of Nicaragua continues to produce disorganized shower and thunderstorm activity. Some development of this system is possible over the next day or so while the system drifts slowly northwestward. Thereafter, environmental conditions are forecast to become unfavorable for additional development as the system turns westward away from land. Regardless of development, this system is expected to bring areas of heavy rain to portions of Central America through tonight.

Interesting:  North Atlantic’s ‘Cold Blob’ May Contain Climate Nuance

Climate observers have long tied the strength of a major ocean current to water temperatures in the so-called “cold blob” in the North Atlantic Ocean. The 965,000-square-mile area south and southeast of Greenland cooled by as much 1.8 degrees Fahrenheit over the past century as other ocean waters warmed.

Some indicators signal that a sustained decline in water volumes in the current, known as the Atlantic Meridional Overturning Circulation (AMOC), is a persistent cause of the blob’s lower temperatures. The current’s degradation began decades ago, a shift likely influenced by climate change that could reduce oceans’ absorption of carbon dioxide and heat, according to a team led by researchers in Penn State’s College of Earth and Mineral Sciences. But they cautioned, the link between AMOC and surface temperatures in the blob, also called the North Atlantic warming hole, is more irregular and complex than previously thought.

As published in the journal Nature Communications, the team found that the diminishing ocean current may impact the North Atlantic climate differently over time, with disparate phases in the relationship between AMOC strength and blob temperatures, said corresponding author Laifang Li, an assistant professor in the Department of Meteorology and Atmospheric Science. The work builds on their finding in 2025 that radiation from the atmosphere helps depress water temperatures.
