Small Craft Advisory…the windiest waters around Maui County and the Big Island
~~~ Hawaii Weather Narrative ~~~
Gusty trade winds remaining active through the week. Here’s the latest weather map, showing strong high pressure systems, in the area north and northeast of Hawaii. These high pressure systems are forecast to maintain both their presence to our north, and their general strength for the time being. This will keep a steady supply of trade winds across our area of the north central Pacific through the next week…which is very common for the summer season.
Here’s a wind profile…of the offshore waters around the islands – with a closer view
Here’s the Hawaiian Islands Sulfate Aerosol animated graphic – showing vog forecast
As usual, with the trade winds blowing…they’ll carry showers our way periodically. As the trade winds remain active…some showers may spread over into the leeward sides on the smaller islands. There will be periods of incoming showers, primarily focused along the windward sides…although not exclusively. This won’t be a steady stream of showers by any means, arriving in an off and on manner through the next week.
Marine environment details: A small craft advisory (SCA) for the typically windy waters around the Big Island and Maui County continues through Tuesday. Little change is expected in the overall wind flow pattern beyond Tuesday, with models showing borderline criteria winds in the areas currently under the SCA. A slight boost in trade wind speeds is expected on Thursday and Friday, before tapering off again this weekend.
A series of moderate southwest swells are due through Thursday, with surf expected to remain below advisory levels. Surf will drop to small Friday and Saturday, with a slight bump Sunday. Choppy wind wave driven surf is expected along the east facing shores. No other major swells are expected.
June Full Moon tonight
Here on Maui – Early Monday morning is dawning mostly clear, with just a few windward clouds. Looking out the windows of my weather tower before sunrise, these low clouds are stretching from the windward sides over the West Maui Mountains. The almost full moon is sinking down into the western horizon. The air temperature was a cool 49.8F degrees at 530am. Meanwhile, at about the same time, the Kahului airport was reporting clear skies, with a temperature of 74 degrees, while Hana was at 72…with the summit of the Haleakala Crater registering 45 degree.
– Mid afternoon, with lots of sunshine beaming down along the north shore, with some high clouds arriving from the west, and clouds over the mountains. These clouds are just beginning to drop a very light mist over my place here in upcountry Kula.
– Early evening, and clouds have definitely increased across the island during the afternoon hours. There have been a few light sprinkles here in upcountry Kula, with even a little fog around the edges. I can also see some blue skies in the distance as well. These little sprinkles have turned into a light shower now at 620pm…here at my Kula weather tower.

Interesting: Once-in-a-generation strawberry moon tonight – Watch for a full moon on the solstice today. This is the first full moon to fall on the June solstice since the year 1967, which some recall as the year of the Summer of Love, a social phenomenon centered on San Francisco, London and other places around the globe. There have been a number of near misses of full moons on June solstices, however. And we are indeed talking about the June summer solstice, not solstices in general. In fact, there was a full moon eclipse on the December solstice in 2010.
Reliably, the phases of the moon recur on or near the same calendar dates every 19 years. It’s the “or near” that causes the full moon to miss the solstice on that 19th year, sometimes. Nineteen years from this year’s solstice – on June 20, 2035 – the full moon will not fall on the same date as the June solstice. It’ll be another near miss, with the full moon falling on June 20, 2035, and the solstice arriving one day later.
It appears as if the full moon and June solstice won’t fall on the same calendar date again until June 21, 2062.
Be aware that, as we’re figuring all this, we’re using Universal Time (UT or its variant UTC), what used to be called Greenwich Mean Time. Universal Time is the favorite of astronomers because it applies to Earth as a whole. What if we used other time zones? Well, for instance, if we use U.S. time zones, the last full moon and the June solstice actually coincided on June 21, 1986.
On June 20, 2016, the moon turns full at 11:02 UTC. The solstice arrives some 11.5 hours later, at 22:34 UTC.
There’s something else special about this full moon, in addition to its falling on the solstice. It marks the fourth of four full moons in between the March 2016 equinox and the June 2016 solstice. Usually, there are only three full moons in one season (between an equinox and solstice, or vice versa), but sometimes there are four.
The third of four full moons to take place in a single season has its claim to fame: it’s sometimes called a seasonal Blue Moon (in contrast to a Blue Moon by the definition of second full moon in a calendar month). The most recent Blue Moon by the seasonal definition occurred on May 21, 2016, or one lunar month before this solstice full moon.
Okay so … seven times in 19 calendar years, a season has four full moons. And in cycles of 19 years, the moon phases fall on or near the same calendar dates.
It should be no surprise that – sure enough, 19 years from now – we’ll have four full moons in between the March 2035 equinox and June 2035 solstice, and the full moon on May 22, 2035, will count as the third of four full moons in one season – a seasonal Blue Moon.
The last time a full moon fell on a solstice generally was in 2010 – the December solstice of December 21, 2010, when the full moon staged an exceedingly rare December solstice total lunar eclipse. There is amazingly accurate Gregoriana eclipse cycle of 372 years, featuring the recurrences of eclipses with the seasons, as defined by solstices and equinoxes.
We find a total lunar eclipse last happening on the December solstice 372 years ago, on December 21, 1638. Looking 372 years ahead of 2010, to the year 2382, we find a December solstice partial lunar eclipse on December 21, 2382. And 19 years after that, in 2401, there’s a December solstice total lunar eclipse on December 21, 2401.
