And in San Jose, California (SF bay area), chiles grow fine all summer/fall but average nighttime low is definitely below 65 degrees F because at most there might be two or three nights all year that don't drop below 65, meaning air temperature, not soil temperature (and personally I'm not sure in many decades I've ever seen a night actually stay above 62-63 in my part of San Jose which is a couple of miles from the bay, and any nights that stay above 60 are rare occurances). --- Brent
