I've found it remarkable the frequency of dew points in the 50s, even 40s still. It's not like temps are averaging well below normal. I think that's what creates the muted summer feel to some people, more so than a lack of extended heat waves. It can be a hot summer here even with only occasional 90s but not when you're still getting multiples days of 50 degree dews into mid July. At least compared to recent memory
