Today’s Weather: Thursday, August 10, 2017

The Summary: NWS says;  Scattered showers, mainly before 7am. Sunny, with a high near 89. Breezy, with a north northeast wind 16 to 20 mph, with gusts as high as 26 mph. Chance of precipitation is 30%. New precipitation amounts of less than a tenth of an inch possible.  Computer Model Tables say 20-23 mph today, which is higher than yesterday. Surf expected to be 2 ft NNE.  We say;  The actual wind at Kanaha will be stronger than the forecast, we think that it will be easily averaging in the low to high 20’s range, gusting into the mid 30’s in the afternoon. The wind direction today should be similar to yesterday with the wind very well filled-in on the inside.  Our “Venturi Factor” Today for Kanaha is 7 out of 10. **Our Gustiness Factor should be lower today at about 35% which is an OK level.

Weather Map: Here is the weather map. You can see that the High to our North is well formed, and that means a better PGF. Our northern isobars have a nice curve that will give us ideal wind directions. The wind could be even more side-shore than yesterday, so winds will be a lot stronger and potentially a little gustier today. These predictions are for the generalized (Tradewind) airflow across the state, and local wind effects (rain/venturi/clouds/etc.) need to be considered. Today’s wind will be a lot stronger than yesterday.

Wind Yesterday:  Here is yesterday’s wind graph, winds gradually came up early averaging in the low 20’s, and then picked up after 4 pm, averaging in the nid-high 20’s. The gusts were up into the high 20’s hitting 30. The highest gusts were about 33 mph after 4pm. The high and low numbers were very far apart with “gustiness” ranging from about 40-50% of the total wind speed.

Moon Phase:  Waning Gibbous, Illumination: 92%. The Moon today is in a Waning Gibbous Phase. This is the first phase after the Full Moon occurs. It lasts roughly 7 days with the Moon’s illumination growing smaller each day until the Moon becomes a Last-Quarter Moon with an illumination of 50%.
Hurricane Season:  Hurricanes are most likely to occur July through December in Hawaii. Hurricanes bring severe bad weather, flooding rain and potentially devastatingly strong winds. The passing of a Hurricane may last days or up to a week or more. The Hurricanes usually develop far away in the eastern Pacific and we generally get several days or more warning of their approach. So there is usually time to make preparations and even evacuate if necessary. Many Hurricanes come close to Hawaii but are just too far away to have a severe effect, This near-miss scenario, and repeated canceled warnings, can give some people a false sense of security. Until one does hit, and then they may be unprepared. Here’s the link to the National Hurricane Center (NHC)
Pro-Tip: Beware of Kites Launching & Landing:
Whenever you are in an area where kites are flying, please take care. Kite Launch Zones are like a little airport with kites constantly taking off and landing. Do not get close to kites unless you are participating in the activity. Make your friends and family aware that they should stay away from flying and launching kites. The best place to watch kiting is from under the trees and away from the main launch/landing areas. This is for everyone’s safety. Please share this information when needed. The safest place to watch a kite is from under a tree, because it is the last place that a kiter will want his kite to be, and it also offers some protection from falling kites too. Remember that even the best kite-flyers will crash their kites occasionally.
