Hawaii’s Mountains – Here’s a link to the live webcams on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii, and atop the Haleakala Crater (~10,023 feet) 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 here in Corte Madera, California, at my friend Linda’s.

Linda and I played Pickleball in Novato, which was fun, although they play hard!

Linda went Tango dancing this afternoon, which gave me some time alone, and then joined some of her friends for a Mussel, pasta, and wine dinner.

The weather here in Marin County today was very warm, although as sun as the sun went down the temperature dropped quickly.

Weather Wit of the day:  Norwegian Meteorologist – Fjordcasters

 

Hawaii’s Broad Brush Weather Overview:  Breezy trade winds will continue for the next couple of days, with passing clouds and showers favoring windward and mountain areas. Lighter winds are expected by the middle of the week, with fewer windward showers and a greater chance for afternoon interior showers each afternoon.

Hawaii’s Weather Details:  High pressure centered far northeast of the state will maintain breezy trade winds through the next couple of days. Batches of moisture caught up in these trades will periodically filter in across the island chain, bringing clouds and showers that will generally focus over windward areas.

A weak upper-level low pressure system will move over the island chain from the west later today, and remain there through mid-week, bringing some instability aloft, which may help to enhance windward showers at times.

Heading into mid-week, a strong low pressure system to the far north will displace the ridge to bring it closer to, or over, the island chain. The proximity of this ridge and the approach of a front/trough from the northwest will bring lighter southeast winds across the area, allowing land and sea breezes to expand in coverage, and generally dominate the local weather regime.

This will lead to mostly clear nights and mornings giving way to afternoon clouds and showers over interior/leeward areas (and possibly vog). An upper level trough will move southeast across the Central Pacific and move overhead by Wednesday evening, bringing cooler temperatures aloft.

The instability associated with this feature combined with pockets of moisture moving across the island chain on the southeast flow, and from the west along the approaching front/trough, may lead to enhanced diurnal showers with brief heavy downpours over island interiors each day through next weekend.

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 / Vog map animation

Hawaii’s Marine Environment:  High pressure northeast of the state will maintain moderate to strong trades through Monday. As a result, a Small Craft Advisory (SCA) remains in effect for the typically windy waters around Maui and the Big Island through 6pm Monday.

The trades will gradually ease Tuesday and Tuesday night, then become further disrupted Wednesday and Thursday, as an approaching front induces surface troughing over the western end of the state. Winds will become light and variable over the western waters as a result, while winds over the eastern islands shift east-southeasterly at light to moderate speeds.

East shore surf will remain at or above normal levels through Tuesday, and will be rather rough due to the strong trades, particularly through Monday. As the trades diminish surf along east facing shores will drop below normal Wednesday through Saturday.

North shore surf will remain very small. A small to moderate sized northwest swell will give a boost to surf along north and west facing shores Monday and Tuesday, followed by a decline Wednesday and Thursday. A new moderate sized north-northwest swell will arrive late Thursday, potentially bringing advisory level surf to north and west facing shores Friday, then lowering next weekend.

Surf along south facing shores will remain small and mostly at background levels through late next week.

Interesting:  Blooming British Isles

Waters off the British Isles sprang to life with colorful swirls in early April 2025. The phenomenon commonly occurs in these North Atlantic waters in spring, but the view from orbit demands the cooperation of clouds.

Clouds stayed well offshore across the archipelago on April 7, 2025. That afternoon, the VIIRS (Visible Infrared Imaging Radiometer Suite) on the Suomi NPP satellite passed over the region and captured this striking image of the waters around the United Kingdom and Ireland.

Some of the colorful swirls, especially those close to shore, are likely due to sediment and other materials suspended in the water. Sediments are carried to sea by large rivers such as the Severn and get churned up from the seafloor by strong currents and waves. Satellite-based research has shown that in the Irish Sea, these mineral particles can exhibit complex spatial and seasonal patterns.
