Both are huge factors but, especially due to the salt on the coast and less fog coverage, it’s been hot and dry there most of the year and when I was 10-15 summer usually included a windbreaker or sweater. Now all summer is 80-100 degrees, and very dry. We used to be snowed out of the house half the winter and now we are lucky to get one storm. It’s drastic with how close we are to the Canadian border there, you really notice how similar weather is these days to the southern east coast.
