No heat wave in New Orelans ~ we're average for this time of year: highs in the 78-82 area, overnight lows still below 70 (barely) and the usual 90%+ humidity.

It'll get hotter. By August the termperature will never go below 80F, not even in the "wee wee hours" after midnight. Our habitually high humidity puts a limit on temperatures, for what it's worth: the damp air prevents the mercury from exceeding 100F no matter what, even during spells when it hits 97-98 every day and never drops below about 85 overnight.
