Our first heat wave since May happened this week, and Friday figured to be the hottest day in more than a month.

Anytime hot weather hits, it’s a good time to remind ourselves of the basics: don’t go in the water alone, know what’s in the water where you’re about to dive, wear a lifejacket (there’s a new kiosk with free jackets at the popular Waterfront Park beach) and hydrate, hydrate, hydrate.
