It is great to be able to winter in Mexico but I sail in southern california during the winter. Why does the service stop because Mike goes south? I need more help finding the wind now than in the summer. I saw that the weather discussion is still given by iwindsurf for northern california. What gives? Why just computer guesses for us in southern california?

mrkhm - good post. I had no idea there was still a "daily dilusion" for other areas, like NoCA. I just assumed it ended for all sites. This is totally bogus.
It would be nice to at least get one forecast a day. Don't need all three.
Someone is pulling the wool over our eyes Evil or Very Mad
IWS Customer Service - are you listening???

NOAA/NWS is a good resource for wind forecasts.
Not sure where you are in SoCA, but you can find specific data for your coastal area. It's updated a few times per day and somewhat accurate.
More so for winter because the storms are easier to track than predicting the micro thermals we get at certain sites due to the topography.
The data is more accurate for the current day and a bit less predictable for the extended portion. Below is a link to get you started.

Hi Everyone,

The Northern California/Bay Area forecasts are ending tomorrow. We picked Northern California and Southern California sign off dates by reviewing the archives to see about which time of year for each region becomes unreliable. To extend the forecasts much beyond that date would mean paying staff to say over and over "another day with little or no wind". We also take into consideration the date when fewer and fewer customers are actually using the site. It would be great keep our staff employed all winter looking for infrequent winds but we can not afford to do so. If a region is on a roll with lots of wind we sometimes extend the forecast season. This year I think we made a good call with our timing.

mkrasnoff has a point about storm winds being much easier to forecast than summer thermals. Even the NWS forecast has some value as do the iwindsurf.com/ikitesurf.com model data.

socalsail's idea of having amateur weather nuts doing supplementary iwindsurf.com/ikitesurf.com forecasts is a good one and we have been working on a way to implement that feature. A lot of you have very site specific local weather knowledge that none of the models are aware of and that I can not factor into the forecast. So your forecasts would be another useful tool for all of us especially in the off season. Contact me at mike@iwindsurf.com if you are interested and I will keep you informed about our progress.

Mike - thanks for the reply and explanation. It all makes sense in terms of feasibility. We only get 2-4 days of wind per month until March here in SoCA.
The summer thermals usually end pretty abruptly sometime in mid to late September and then we're into a bit of Santa Ana roulette winds and then storm related clearing winds.

As long as the sensor stays working consistently at Leo, the Malibu sailors will be happy campers. A little south swell wouldn't hurt either Very Happy

Mahalo & Aloha
