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.

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

It’s mostly clear with hazy conditions early this morning, with a cold low temperature of 46 degrees at my place. 

335pm, variable clouds here in Maui County, ranging from cloudy to mostly sunny, although there’s quite a bit of volcanic haze the air as well.

The earlier afternoon clouds have mostly cleared as enter the early evening hours, leaving a few streaks of high cirrus clouds. The cold front is bearing down on Kauai, and some of the associated showers are quite heavy.

Hawaii’s Broad Brush Weather Overview: A cold front will move across Kauai and Oahu tonight into early Wednesday, then stall across the central islands late Wednesday through Thursday. This will bring periods to showery weather to most islands this week. More unsettled weather is possible Friday through the weekend, as a plume of deep moisture develops along another front, as an upper-level disturbance moves across the state. Drier weather and improving conditions are then expected early next week as ridging builds across the region.

Hawaii’s Weather Details:  Satellite imagery shows a cold front just west-northwest of Kauai. Moisture ahead of the front is resulting in pockets of clouds and showers across the western islands. Elsewhere, localized sea breezes, due to light to moderate east-southeasterly flow, is producing some clouds over island interiors. Expect little change through this evening.

Guidance continues to show the front moving towards the state, then across Kauai late this evening and Oahu by early Wednesday morning. The progressiveness of the front should slow considerably later tonight, as the mid-level flow becomes parallel to the front. Nonetheless, expect an increase in clouds and showers across the western islands tonight into early Wednesday, with breezy cool northerly winds developing in the wake of the front.

Model guidance then shows the front stalling over the central islands late Wednesday through Thursday, as a trough moves overhead. The will help to maintain clouds and showers across most islands, with some enhanced showers possible over windward and mountain areas of Oahu and Maui County.

Late in the week and over the weekend, the model solutions suggest some more uncertainty in the forecast. Overall, the pattern appears to favor a somewhat unsettled period, as moisture pulls along the stalled frontal boundary, and upper level troughing moves overhead. Improving conditions are then forecast for early next week as deep layer ridging builds over the island chain.

Hawaii’s Marine Environment: A cold front approaching the area will reach Kauai late this evening, then Oahu early Wednesday, before stalling and weakening near Maui County by Thursday. Light to moderate south to southeast winds will shift to northerly and strengthen along and behind the front. This will prompt Small Craft Advisory conditions, particularly over the Kauai waters beginning tonight, and potentially around Oahu by Wednesday as the front progresses down the island chain.

Seas will respond and become rough over these waters, potentially nearing or reaching advisory-level seas tonight into Wednesday. High pressure will build north of the state Thursday into Friday, followed by another frontal system evolving west of the state that may approach this weekend.

Surf along exposed north- and west-facing shores will remain small, as a medium-period north-northwest swell lingers. An upward trend is expected as a fresh, long-period west-northwest swell arrives and builds down the island chain. Offshore buoy observations reflect this trend, showing increasing energy in the 16 to 17 second bands.

Strong northerly winds associated with the front, combined with near advisory-level surf, will result in rough conditions along exposed north-facing shores of Kauai and Oahu as this swell peaks. Elsewhere, surf is expected to remain below advisory levels. Overlapping pulses expected Wednesday and Thursday, similar in size, will support surf holding near advisory levels for exposed north- and west- facing shores, mainly on Kauai and Oahu, through the second half of the week. A downward trend is expected late Friday into the weekend, with mainly a small, long-period west-northwest swell anticipated.

Surf along east facing shores of Kauai and Oahu could rise into Wednesday, in response to the strong north-northeast winds accompanying the front. Otherwise, surf should remain below average this week due to the lack of fresh to strong trades locally and upstream.

Interesting:  How Oysters are Impacted by Environmental Conditions and Farming Practices

The Rhode Island aquaculture industry is more robust than ever. The value of aquaculture products was $8,795,493 in 2024 and 89 active aquaculture farms covered 392.5 acres, according to a report by the Rhode Island Coastal Resources Management Council.

Eastern oysters account for approximately 99% of the state’s aquaculture production, the report noted. Jacqueline Rosa, who is pursuing her master’s degree in oceanography from the University of Rhode Island Graduate School of Oceanography, spent 18 months conducting field work on how water quality and farming practices impact these mollusks.

Eastern oysters grow in Narragansett Bay and Rhode Island’s salt ponds. Rosa’s field work was done in the lower west passage of Narragansett Bay, an area that hosts 48 acres of oyster farms.
