I caught my biggest wild Brookie on a super windy February day. Usually the type of weather patterns (other than thunderstorms and remnant tropical systems) that produce high winds in PA tend to be colder season (say mid November through mid April or so) strong cold fronts. Ahead of it you get strong, and generally warm-ish winds out of the south, and behind it you get a dry, cold wind out of the northwest. The key to fishing on days like this IMO is to find streams that have a mountain as a natural windbreak. Meaning on the warm, southerly flow days find a ridge that runs roughly east/west, and fish a stream on the northern side of that ridge. On the cold NW wind days, find a ridge than runs SW to NE (there are lots these in PA) and fish a stream on the SE side of the ridge. The day I caught that big Brookie you could hear the wind howling over the ridge to the NW, but in the valley along the stream it wasn’t bad at all.
