Windy is great. The map is appealing, but be sure to check out the forecast view for a particular location. Also make sure you try different locations. I'm in the Salish Sea on Orcas Island in the San Juans and because we have a lot of topography here mixed with ocean, we have a lot of local effects, contour winds and so on and there are big differences between locations.<p>Also note that Windy can get it wrong. I grew up in Cape Town and forecasting there is easy compared to here because it's the tip of Africa surrounded by Atlantic and Indian Ocean. Here it's very mixed with land, sea, big 11,000ft mountain ranges like the Olympics and so on and this region is hard to forecast. For where we are, the forecasts - and Windy's map specifically - is wrong fairly often.<p>A trick that a lot of folks don't know about is using ATIS, AWOS or ASOS at a local airport or airfield. If you want to know what the weather is at a given location, find a nearby airport, get their ATIS (or AWOS or ASOS) phone number and you can call and get a real-time report that is extremely accurate. I do this for KORS, our local airfield all the time. You can get this data off Foreflight although I'm sure there are plenty of free alternatives. Obviously it's current weather, not forecast, but it's often helpful.
