This is my go-to weather source to get historical averages, probability for precip, number of hours per day when I do not need artificial light, average winds, etc.

Pick an airport so that there is historical data when you want to research an area for a trip. Note that they consider a day with precip to have had at least a millimeter of precip, so it will often be wetter than that website predicts.

That said, for your initial trips that are close to home, just use your local weather forecasts. The Weatherspark site is best used when planning for an area that you are not familiar with.
