This is the week. Overnight lows offer little recovery either, sliding from 69°F tonight up to 75°F by mid-week — meaning your body never fully resets between hot days.Winds stay gentle throughout, mostly south and southwest at zero to five miles per hour, with a brief bump to around ten by Thursday.
