Air Temperatures ranged between these warmest and coolest spots near sea level – and on the highest mountain tops on Maui and the Big Island…as of 610am Saturday morning:
Kailua Kona – 74
Hana, Maui - 66
Haleakala Summit – 37 (near 10,000 feet on Maui)
Mauna Kea Summit – 30 (13,000+ feet on the Big Island)
Hawaii’s Mountains – Here’s a link to the live web cam on the summit of near 13,800 foot Mauna Kea on the Big Island of Hawaii. This web cam is available during the daylight hours here in the islands…and when there’s a big moon shining down during the night at times. Plus, during the nights you will be able to see stars, and the sunrise and sunset too… depending upon weather conditions.
A cold front is stalling near the Big Island today, with cloudy
skies and some showers in its wake…mostly along our windward
sides of the islands
An upper trough of low pressure will exist to the east of the state
Monday and Tuesday…with possible enhanced windward showers -
otherwise a trade wind weather pattern is slated through Friday
Another front is expected to arrive next weekend – which could
bring us strong and gusty trade winds, and locally heavy showers
High Surf Warning…north and west facing shores of Kauai, Oahu,
Molokai, and the north shore of Maui – into Sunday
Small Craft Advisory…all coastal and channel waters –
through noon Sunday
The following numbers represent the most recent top wind gusts (mph), along with directions…as of Saturday morning:
12 Poipu, Kauai – NNE
12 Kuaokala, Oahu – NE
08 Molokai – SE
05 Lanai -NE
14 Kahoolawe – NNE
05 Kaupo Gap, Maui – SE
17 Kealakomo, Big Island – NW
Here are the latest 24-hour precipitation totals (inches) for each of the islands…as of Saturday morning (545am totals):
1.17 Kilohana, Kauai
1.57 Moanalua RG, Oahu
4.08 Kaupo Gap, Maui
2.25 Island Dairy, Big Island
We can use the following links to see what’s going on in our area of the north central Pacific Ocean. Here’s the latest NOAA satellite picture – the latest looping satellite image… and finally the latest looping radar image for the Hawaiian Islands.
~~~ Hawaii Weather Narrative ~~~
Our winds will be generally trade winds in the wake of the recent cold front…lasting through the rest of the new week ahead. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean. Here’s a real-time wind profile of the central Pacific…centered on the Hawaiian Islands. ~~~ We continue to see several low pressure systems far west, northwest and north of the state, with a cold front now stalled near the Big Island. Meanwhile, we see a high pressure system moving by just to the north of the state…with a ridge of high pressure extending southeast offshore of our windward sides. Our winds will come in from northeast, with trade winds remaining active through most of, if not all of the next week. They will start off on the light side today into Monday, and then pick up in strength Tuesday onwards.
Satellite imagery shows a wide band of clouds over the state…associated with the cold front now over the Big Island. Here’s the looping radar image, showing light to moderately heavy showers over the state, especially across the central islands from Kauai down to the northern part of the Big Island. The leading edge of the cold front has moved just offshore to the southeast of the Big Island at the time of this writing. Looking at this larger satellite image, which is in the looping mode, we can see this large swath of clouds, associated with the cold front.
We’re now moving into a prolonged period of trade winds, which is something we haven’t seen for quite a while. It will take a while before we see the high and middle level clouds, associated with the dissipating cold front, move away…likely by tomorrow. There will continue to be some showers today, which will fall generally along our windward coasts and slopes. The upcoming work week should find pretty nice late winter weather conditions, with the best sunshine possibilities over the leeward beaches. Looking towards the future, we could see another late winter cloud band arrive next weekend. Next weekend’s cold front will usher in strong and gusty trade winds, and a period of cool showers, stayed tuned for more information on that. I’ll be back many times during the day with more updates on all of the above, I hope you have a great Saturday wherever you’re spending it! Aloha for now…Glenn.
Here on Maui, at the 3,100 foot elevation, at my upper Kula, Maui weather tower, the air temperature was 59.5 degrees at 650am on this Saturday morning, under cloudy skies.

Interesting: How much water do YOU use each day? – Many Americans are confused about the best ways to conserve water and have a slippery grasp on how much water different activities use, according to a national online survey conducted by Indiana University Assistant Professor, Shahzeen Attari. Experts say the best strategy for conserving water is to focus on efficiency improvements such as replacing toilets and retrofitting washing machines. However, the largest group of the participants, nearly 43 percent, cited taking shorter showers, which does save water but may not be the most effective action. Very few participants cited replacing toilets or flushing less, even though toilets use the most volume of water daily.
The results of the survey of 1,020 participants are detailed in the article “Perceptions of Water Use” by author Shahzeen Attari, of Indiana University Bloomington’s School of Public and Environmental Affairs. The article appeared March 2 in Proceedings of the National Academy of Sciences.
“People may be focusing on curtailment or cutting back rather than efficiency improvements because of the upfront costs involved,” Attari said. “It is also surprising how few participants mentioned retrofitting their toilets. Even though toilets use less water volumetrically than washers and showers per use, the frequency of use results in the highest water use overall.”
The survey then asked participants to estimate water used by 17 different activities such as using a carwash, taking a shower for 10 minutes, using a standard flush and so on. Results show that on average, participants underestimate water use by a factor of two, with severe underestimates for activities that use a lot of water. This is somewhat encouraging news as Americans seem to underestimate water use less than they do energy use, which was underestimated by a factor of about three, as illustrated by Attari’s previous research also published in PNAS.
Many side factors lead to better accuracy in people’s perceptions of water and energy use. For instance, participants with stronger pro-environmental attitudes have more accurate perceptions of energy use but not for water use. Being older and being male lead to more accurate perceptions of water use but not energy use. Finally, numeracy, or the ability to understand and apply numerical concepts, is an important factor for accuracy in both water and energy use perceptions.
Finally, and not surprisingly, participants had no clue about how much water was needed to produce four particular foods: rice, coffee, sugar and cheese.
“Given that we will need to adapt to more uncertain fresh water supplies, a problem that the state of California is currently grappling with, we need to find ways to correct misperceptions to help people adapt to temporary or long-term decreases in freshwater supply,” Attari said.
