I live on my boat and when I travel Tides are a very handy feature. Lately I’ve noticed that the times for high and low tide are off. I’m currently in Key Largo Florida USA and when comparing to other tide sources Windy tides appear to approximately two hours off. Is this some setting I don’t know about? Key Largo is currently on eastern daylight savings time (-4:00 GMT). Thanks for your help. GREAT program!
