Wind apps and real time/continuous wind data
How to Find Wind - Wind Forecast Models Tutorial - Wingfoil
As Reivers' Uncle Claude1) used to say, “It's better to grab the bull by the tail, not the horns. Then you can let go when you want to.” When a blow is coming through that will provide downwind opportunities, it can be safer to go out after the peak winds have passed and are diminishing rather than early on while the winds are still growing and max roughness of conditions and exact arrival time of peak winds have not yet been determined.
One fundamental aspect of using weather apps and weather websites is to understand that none of them are perfect. With use you can learn to identify local weather patterns for which the apps tend to have greater accuracy and patterns which present problems for them (and consequently should lead you to the clear understanding that such problematic patterns result in less predictable conditions on the water and increased risk for you).
Bloody excellent summary of what the weather is about.
Something worth doing is finding out who knows the most about your area (sailors, windsurfers, surfskis etc. They will add some nuance to the computer generated forecasts. Surfline is pretty good with their analysis.
