What time of year?

When is this supposed to happen? Most of the movie keeps reminding us how scorching Corpus Christi is, so it's presumably summer, maybe September at the latest, unless they were having an intense autumn heat wave. Binx doesn't worry about school, either, so probably August before the school year started, although he might be a high school dropout. But Lloyd doesn't worry about college, either, and his father wouldn't be happy about him falling behind in his studies. Then at the end, they move to snowy Vermont and Binx still has his arm in a sling. Unless he heals really slowly or was severely injured like with shattered ribs, that shouldn't be more than a month. But Vermont's ski resorts don't open until sometime around the New Year, about four months later.
