I only use IWindsurf too for wind forcast.I actually look at it every day.The NOAA forcast is useless.Dont even look at it anymore.Look to fish on a day with south to west wind less than 10mph the whole time you are fishing.The problem with going with a charter,is that you schedule trip and place deposit to fish on a specific day.The forcast is only dependable starting 2 days away and that is not entirely dependable with storms and multiple fronts coming thru at the time you are looking.Seams the charters schedule not as full this season due to this pandemic.So weekdays probably will be open.Could find a charter to take you on one days notice middle of week when forcast calls for a flat lake.Good luck.
