Frankly, I don't leave the house without checking Windy to know whether I should take my paraglider, raincoat, skis, swimming gear or just not go out. Many have told me about other fantastic forecasting tools they use to make decisions. I've tried them and keep coming back to Windy which is always right and gives more detailed information than anyone can want. The subscription price is very reasonable, so if you've spent thousands on a wing or boat why not spend another €19 to know you're not going to end up on the rocks or in a tree?
