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 at home here in upper Kula, Maui, Hawaii

It’s mostly clear with some clouds along the windward sides here in Maui County, with calm winds at my place, and with a low of 50 degrees and the relative humidity is 80%


>>> Highest Temperature Saturday, June 6, 2026 – 113 degrees at Death Valley, CA
>>> Lowest Temperature Sunday, June 7, 2026 – 20 degrees near Kirk, OR

Hawaii’s Broad Brush Weather Overview…as of Sunday morning: Breezy trades will persist, then gradually weaken to moderate speeds by the latter half of the new week. Periodic showers will filter in on the trade wind flow, mainly focusing over windward and mountain areas. By next weekend, the winds may become light enough to support land and sea breeze development.

Weather Details for the Hawaiian Islands…as of Sunday morning: Radar and satellite imagery shows scattered showers moving over windward and mountain areas, with limited spillover into leeward areas across the state.

The forecast through the upcoming week revolves around gradual fluctuations in trade wind speeds, and the timing of minor batches of moisture that will move across the state on the trade wind flow. Guidance remains in good agreement on the surface high to the northeast of the state continuing to drive breezy trades across the state through the rest of today.

This high will weaken slightly Monday into Tuesday, then get pushed further northeastward through the rest of the week, as a series of low pressure systems move across the northern Pacific, and a cold front approaches the area from the northwest.

The evolution of the surface high will cause the trades to gradually ease through the week. For the latter half of the week, winds may be light enough to support land and sea breeze development, bringing afternoon clouds and showers to leeward and interior areas, and partial clearing at night.

Here’s a near real-time Wind Profile of the Pacific Ocean – along with a Closer View of the islands / Here’s the latest Weather Map / Looping Surface Precipitation…through the next 8-days / Vog Map

 

Marine Environmental Conditions…as of Sunday morning: Surface high pressure will remain anchored far northeast of the islands through early in the new week. The Small Craft Advisory (SCA), currently in effect for all local waters, will be trimmed back to the typically windy waters around Maui and the Big Island, due to a slight weakening in the trades.

During the middle of the upcoming week, a ridge north of the islands, associated with the high, will be weakened and depressed southward. As a result, trades will drop further and allow the SCA to be cancelled entirely Tuesday or Wednesday.

Long-period forerunners of the next south swell should begin to show up on the near shore buoys today. Energy from this swell is expected to peak late Monday into Tuesday, and bump up surf to slightly higher than the June average, but still below advisory criteria. Expect this swell to fade through mid-week. A smaller pulse of south-southwest swell is due late Thursday and Friday, and a more significant south-southwest swell is on track to arrive next weekend.

A small west-northwest swell will produce tiny north shore surf through early in the upcoming week. Rough surf along east- facing shores will remain around seasonal average today, then slowly decline through the middle of the week as trade winds ease.

>>> Eastern Pacific: 

Tropical Cyclone 01E (Amanda)

AMANDA FORECAST TO BECOME A POST-TROPICAL REMNANT LOW SOON

According to the NHC advisory number 20…Amanda is located about 1425 ESE of Hilo, Hawaii

The depression is moving toward the southwest near 5 mph and turn toward the west-southwest is expected today. Maximum sustained winds are near 35 mph with higher gusts. Amanda is expected to become a post-tropical remnant low by tonight.

 

Tropical Cyclone 02E 

TROPICAL DEPRESSION FORMS SOUTH OF MEXICO……TROPICAL STORM WARNING ISSUED FOR A PORTION OF THE SOUTHERN COAST OF MEXICO

According to the NHC advisory number 1…Amanda is located about 95 south of Acapulco, Mexico

The depression is moving toward the northeast near 6 mph and a turn toward the north is expected tonight. On the forecast track, the center will be nearing the coast of Mexico within the warning area early Monday. Maximum sustained winds are near 35 mph with higher gusts. Some strengthening is forecast, and the depression is expected to become a tropical storm before reaching the coast.

 

>>> Offshore of Central America:

Invest 92E

Shower and thunderstorm activity associated with a broad area of low pressure offshore of Central America has changed little in organization this morning. Some development is still expected, however, and a tropical depression is likely to form during the next day or two while the system moves slowly northward toward the coast of Central America. Interests along the Pacific coasts of northwestern Costa Rica, Nicaragua, Honduras, and El Salvador should monitor the progress of this system. Regardless of development, heavy rainfall and life-threatening flash flooding are possible across portions of Costa Rica, Nicaragua, El Salvador, and Guatemala through early this week.

* Formation chance through 48 hours…high…70 percent
* Formation chance through 7 days…high…70 percent

Interesting:  Giant Fan-Shaped Geological Structure Discovered Beneath East Antarctica

An international team of researchers including our Department of Geography has discovered a vast geological structure hidden beneath the East Antarctic Ice Sheet.

Enormous Subglacial Basins

The structure is made up of a system of enormous subglacial basins buried in ice over three kilometers thick in parts.

Together, the basins form a giant fan-shaped structure on a continental scale. The team have named it the East Antarctic Fan-shaped Basin Province.

It includes some of Antarctica’s best-known subglacial features, such as the Wilkes and Aurora basins and the basin hosting Lake Vostok, the largest known subglacial lake on Earth.
