I lived in NO for ~5 years, it gets that high and worse during the summer. End of September might be better but not by much.
In New Orleans, the morning temperature in July is usually 70-80 with 90+% humidity.
However, when in the afternoon it heats up to the mid-upper 90s, the humidity is usually around 60-70%. This is not because the air got less humid, there's just as much water/humidity in the air as there was at the cooler temperature, it's simply that the air is capable of holding a LOT more water as the temperature climbs.
Technically, 90% humidity at 90 degrees F is a dew point of around 86f. It's VERY uncommon for dew point to get that high anywhere. It can happen, but it's not common.
That said, Any dew point over about 60 deg F feels sticky or uncomfortable to most people. And any dew point over about 70 feel downright oppressive. (at this point people start dropping dead from the heat.)
