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 (out of operation). 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’s Weather Highlights…as of Tuesday afternoon: Relatively weak trades will continue through Friday, with increasing wind speeds this weekend. An upper low and mid-level trough will bring an increased chance of showers to the western end of the state over the next few days. Showers will shift to the eastern end of the state this weekend as an area of tropical moisture passes by.

Weather Narrative..as of Tuesday afternoon: An upper low to the west, and associated mid-level trough will linger over the next couple of days, and enhance incoming trade wind showers, particularly across the western half of the state. This upper low is forecast to lift away to the north on Friday returning more stable conditions to the area.

Trades will be weaker than normal through Thursday, as the remnant of former tropical cyclone Genevieve lingers, between the subtropical high and Hawaii. As a result, trades will be weak and localized sea breezes will bring interior and leeward cloud build ups each afternoon.

Across Kauai and Oahu, scattered showers may develop during the afternoons due to the instability and low level moisture from the upper low/trough described above. Trades will increase this weekend, doing away with most of the sea breeze effects. This weekend guidance suggests a plume of moisture coming either over or very close to Maui and Big Island.

Marine Conditions…as of Tuesday afternoon: Moderate trade winds will prevail over the coastal waters for the next few days, as the remnants of former Tropical Cyclone Genevieve continue lifting northward, well northeast of the area, and a front passes from west to east across the North Pacific. Winds are expected to remain below Small Craft Advisory levels through much of the week. Trades are forecast to restrengthen to locally breezy levels by the end of the week, as what is left of Genevieve`s remnants dissipate and high pressure expands north of the state.

Surf along south-facing shores will remain below seasonal averages through much of this week, though occasional small fluctuations can be expected, as small swells move through. By this Saturday, a small, long period south swell is expected to arrive, followed by a series of reinforcing south swells that will boost surf heights to near or above seasonal averages into next week.

Small, medium period easterly swell generated from former Tropical Cyclone Genevieve continues to linger, but will gradually ease over the next couple of days. Choppy conditions will remain, generated by the moderate trade winds. Surf along north facing and west shores will remain flat to tiny, except for areas exposed to the easterly trade wind wrap.
