Today’s Weather: Friday, August 11, 2017
The Summary: NWS says; Sunny, with a high near 88. Windy, with a north northeast wind 14 to 19 mph increasing to 20 to 25 mph in the afternoon. Winds could gust as high as 37 mph. Computer Model Tables say 21-24 mph today, which is higher than yesterday. Surf expected to be 3 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 high 20’s range, gusting into the high 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 gentle curve that will give us ideal wind directions. The wind should be more side-on-shore than yesterday, so winds will be a lot stronger and potentially a little less gusty 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 even stronger than yesterday.

|Moon Phase: Waning Gibbous, Illumination: 85%. 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: LOOK BEFORE YOU JUMP:
Whenever you are about to jump, you must look first to see if the area is clear. Never jump if someone is in your landing zone. Never jump over people or put other people at Risk. You must also be able to read the on-water traffic and anticipate where people will be when you land. Be responsible when kiting and Kite Safely. Do not be a reckless kiter always riding out-of-control. Real skill comes from experience and knowing your limits. Always keeping safe distances away from people for when you do lose control and crash, which you ultimately will. There is Never any reason to put other people in danger. Remember: Look before you jump, and do not jump when people are near you.
