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 home here in upper Kula, Maui, Hawaii.

It’s mostly clear to partly cloudy here in Maui County this morning….with some cloudy areas. The low temperature at my place was 51 degrees.

3pm, it’s one of those SUPER SUNNY tropical days…with hardly a cloud in the sky!

Clouds are clearing and the bright moon is shining down. The temperature here at my Kula weather tower at 906pm has dropped to 62 degrees.

June Precipitation Summary for Hawaii:

June began with high pressure far to the northeast and a deep surface trough to the west of Kauai drew in higher moisture with east-southeast winds. This led to active windward showers around Kauai and Oahu and some sea breeze-driven showers on leeward Oahu, with totals reaching up to 0.25 inches. The wettest windward spots, especially in the terrain of Kauai and Oahu, recorded between 0.5 to 1.5 inches of rainfall. The next couple of days were dominated by moderate to breezy trade winds and mostly dry conditions, with isolated to scattered windward and mountain showers.

Early morning showers returned June 4–5 along the Kona slopes of Hawaii Island (2-day totals around 0.5–1 inches). A decaying front and upper disturbance enhanced rainfall across windward areas on the 6th, enhancing windward and mountain showers, with rainfall up to 1.5 inches in some areas, and around 2 inches at Mt. Waialeale. Weaker trades and sea breezes on the 7th and 8th led to afternoon showers along Kona slopes (0.10 to 1.25 inches, and up to 2 inches near Kealakekua on the 8th), with light rainfall in interior Kauai and Maui. Elsewhere, upper-level troughing and stable mid-levels brought little more than high clouds and minimal additional. Light to moderate trades persisted on the 9th and 10th, with a surface trough west of Kauai and weakening inversion delivering increased moisture and windward showers, mainly over Kauai and Oahu.

Trades strengthened to locally breezy June 11th through the 17th as high pressure built north of the state. Most areas remained dry during this stretch, though a few shallow moisture bands brought scattered windward and mountain showers. Gauges recorded up to 0.25 inches on the night of the 12th to 13th (highest totals on Hawaii Island and Maui), with widespread showers (0.25 to 0.75 inches, locally near 1 inch) across the islands on the night of the 16th into the 17th. Beginning on the 18th, trades weakened slightly as the high shifted eastward. Moderate showers fell on the Kona slopes (0.25–1 inches) through the 20th. Trades returned to breezy-to-locally-strong by the 21st with minimal rainfall statewide.

A weak upper trough passed north of the islands June 23–25, enhancing windward/mountain showers. Kauai saw the heaviest rain (up to 2.9 inches at Mt. Waialeale), with 0.25–1 inches on Oahu and Maui, and 0.25–1.5 inches on Hawaii Island. June closed with breezy trades and generally drier conditions. However, on the 30th, southeast winds allowed localized leeward/interior showers, including 0.1–0.5 inches over interior valley sites of Oahu (around Pearl Harbor), ~0.15 inches for leeward Kauai, and up to 1 inches on the Kona slopes.

Hawaii’s Broad Brush Weather Overview: A strong high pressure ridge north of the Hawaiian Islands will continue to produce breezy to windy trade winds, with the strongest winds focused across Maui County and the Big Island. Dry weather conditions will combine with these strong gusty winds to keep elevated fire danger across the state, mainly over the drier leeward slopes. Winds will ease starting Wednesday, with a ridge aloft confining brief passing showers to mainly windward and mountain areas.

Hawaii’s Weather Details: Strong high pressure north of the state will maintain breezy to windy easterly trade winds across the island chain. A Wind Advisory remains in effect for the windier areas of Maui and Hawaii Counties; including the summits of Mauna Kea and Mauna Loa on the Big Island. Given the latest trends and model guidance the Wind Advisory expire soon, but would not be surprised to see isolated advisory gusts continue into the night.

In addition, the relatively dry humidity levels will combine with the strong winds to keep elevated fire weather conditions across the state, mainly over drier and windier leeward areas.

Satellite imagery continues to show bands of fairly stable clouds moving into windward and mountain areas, with radar imagery showing light passing showers moving across the islands. The ridge aloft continues to keep inversion heights around 5,000 to 6,000 feet based on soundings at Hilo and Lihue.

The pattern will begin to change tonight into Wednesday, as high pressure north of the state weakens. This will allow our strong winds to gradually weaken overnight, with moderate to breezy trades expected for the rest of the week. As the high weakens we’ll also see the inversion lift back to around 7,000 to 8,000 feet. This will allow clouds to grow higher, with a return towards typical summer time trade wind weather expected. An upper level low just southwest of the islands will help to enhance sunrise and sunset colors as cirrus clouds stream high overhead.

Fire weather: Breezy to windy trade winds with stable and relatively dry conditions will persist. Minimum relative humidity at lower leeward elevations has fallen to around 45 percent, and with the temperature inversion dropping to as low as 5,000 feet, winds will become gusty over and downwind of island mountains. This will result in near critical fire weather conditions over dry leeward areas during the afternoon hours.

Hawaii’s Marine Environment: High pressure will remain nearly stationary far north of the islands, which will support continued fresh to strong trades across the area. The Small Craft Advisory remains in effect for all Hawaiian coastal waters through 6pm Tuesday. The surface high will move eastward and weaken slightly during the second half of the week, but winds are likely to remain breezy to locally strong in the windier channels and waters of Maui County and the Big Island. Therefore, the SCA will likely need to be extended for these areas. Additionally, seas will rise in the Alenuihaha Channel over the next couple of days.

South shore surf is expected to slowly decline as the current small south swell fades. The next small, long-period south swell is expected to arrive and peak on Wednesday. This swell may boost south-facing shore surf heights slightly from tonight through Wednesday before gradually easing again through Friday. Guidance shows that another, smaller long-period reinforcement could arrive Friday night into the first half of the weekend.

Surf along east-facing shores will be rough and choppy for the next couple of days, in response to the gusty easterly trade winds. As the trades ease a bit during the latter portion of the week, surf along east-facing shores will also trend down.
