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 Saturday comments:  I’m here at home through the winter in upper Kula, Maui

It’s mostly clear here in Maui County early this morning, although with some streaky high cirrus clouds…with a low temperature of 52 degrees at my place.

I’m heading over to Haiku for a session of Pickleball, then shopping in Paia, and back here early this afternoon for the next weather updates.

Pickleball was fun, although the parking in Paia on my way home wasn’t, as there were too many cars looking for parking spots.

The moon is still very bright, although is gradually becoming slightly smaller…from the recent full moon.

Mauka Showers web blog…The Central North Pacific Hurricane Season, 2025 Edition

 

Hawaii’s Broad Brush Weather Overview: Moderate trade winds with embedded showers favoring mainly windward and mountain areas are expected into Sunday, followed by drier conditions early in the work week. By Tuesday and Wednesday, winds will become light and veer southerly as a cold front approaches the state from the northwest. The front is expected to move over the state during the second half of the week bringing increased shower chances.

Hawaii’s Weather Details: The surface trough west of Kauai has continued to weaken and lift northwestward away from the Hawaiian Islands. Meanwhile, drier conditions have been observed across the state, with latest satellite and radar imagery showing very few clouds or showers. Also of note, episode 38 of the ongoing Kilauea eruption began this Saturday morning, sending a plume of primarily water vapor and sulfur dioxide gas to near 35,000 feet.

This plume then spread eastward over portions of the Puna District due to strong westerly flow aloft. However, radar echo tops and webcams show that emissions from Kilaua have reduced and lowered back down to about 20,000 feet, and are now being transported in the more typical southwesterly direction within northeasterly flow.

Moderate trades will continue to decrease slightly tonight, as an upper level trough moves overhead. This slight instability overnight could help provide some enhanced showers, but these should be brief and mainly focused along windward and mountain areas. Model guidance is also suggesting that a band of moisture, currently seen on regional satellite imagery within the offshore waters to the east, will arrive during the morning hours Sunday, sustaining windward shower chances for mainly the eastern end of the state.

The upper level trough is expected to continue digging southeast of the state Sunday, and eventually form a closed low east of the state early Monday. As low and mid level ridging builds in from the west, stable and mostly dry conditions are expected with moderate trade winds. Any showers that do occur would be a result of brief pockets of low level moisture trapped within the trade wind flow, and would mainly focus along windward areas. The one exception is for the Kona slopes of the Big Island, where typical sea-breeze induced cloud buildups, and a few showers will be possible during the day.

Models continue to indicate that a cold front will approach the Hawaiian Islands from the northwest Tuesday. As this occurs, background surface winds will become light and veer southeasterly, allowing for daytime sea breezes and nighttime land breezes ahead of its arrival. Timing and impacts of the front remain uncertain, with the ECMWF model offering an earlier arrival late Wednesday, and more modest impacts than the GFS’s later arrival on Thursday with stronger lift and upper level support for enhanced shower chances.

Fire weather: The inversion slopes from around 7,000 feet at Lihue to 11,000 feet at Hilo. A slightly drier airmass has filtered in, but moderate trades are unlikely to reach the critical fire threshold and will ease slightly tonight. Light southeast winds are expected Tuesday preceding a wetter weather pattern during the middle to second half of next week.

Hawaii’s Marine Environment: A surface trough west of Kauai will continue to weaken and drift slowly westward away from the islands through Sunday. A surface high pressure ridge will remain north of Hawaii, winds flowing around this ridge will produce moderate to locally strong easterly trade winds today, then wind speeds will slowly decrease Sunday onward.

Lighter southeast to south winds are forecast from Tuesday to Wednesday as another cold front moves into the region from the northwest. A consensus of weather model guidance suggests this cold front may move into the western Hawaiian islands from late Wednesday into Thursday.

A Small Craft Advisory (SCA) remains in effect for the typically windier waters around the islands in Maui and Hawaii Counties. Trade winds will drop below SCA thresholds by tonight.

The current medium period north-northwest (340-350 degree) swell continues to slowly decline. Buoy observations from National Data Buoy Center stations 51001 and 51101 just northwest of Kauai show a gradual downward trend. The latest swell model guidance confirms this downward trend as the current north-northwest swell energy will gradually fade into Monday, bringing surf back down to below average levels for this time of year. The next two long to medium period overlapping northwest (310-320 degree) swell pulses will arrive on Monday and Tuesday, boosting surf along north and west facing shores, possibly reaching marginal advisory levels by Wednesday.

Choppy east shore surf will remain small and decline this weekend as trades ease. Expect minimal background energy for south facing shores through the next few days, other than a slight rise this weekend.

Peak monthly tides combined with water levels that are running higher than predicted will likely lead to minor flooding along the shoreline and in low-lying coastal areas. Coastal flooding is possible around the early morning peak tide through Sunday.

Interesting:  Hurricane Season Ends, But Weather Woes Push Floridians to Move

Although the Atlantic hurricane season has officially ended, Floridians’ woes over severe weather and soaring homeowners’ insurance costs still linger. A new Florida Atlantic University survey finds hurricanes and other climate-related threats are causing many Floridians to consider moving.

The Florida Climate Survey found that 36% of respondents statewide had moved or were considering moving in part or fully due to weather hazards. Broken down by region, the results show that threats such as hurricanes, flooding and extreme heat have already influenced some Floridians to relocate.

Nearly a quarter of North Floridians (24%) reported that these factors contributed to a previous decision to move within the state. Across much of the peninsula, from Tampa to Cape Canaveral south, about 20% of respondents report that weather hazards play a role in them exploring a move.
