Here in LA, early September is often the hottest time of the year, with daytime temperatures usually in the 90s or 100s and nighttime temperatures in the mid 60s or higher(Fahrenheit, of course). Unless purple is the color that goes with heat exhaustion, I'm leaning away from temperature as the explanation.

I didnt realize that about Cali. and as i said all that I know is based off of Ohios Odonates...

BTW is it that warm/hot all year?

The real heat is from mid-July through mid-September. In the spring and early summer it's cool and cloudy in the mornings and gets moderately hot some afternoon, in the fall it ranges from moderately cool to moderately hot, and it only gets chilly from about mid-December to late February (by Ohio standards, it never gets really cold). Right now it gets down to the 40s and occasional 30s at night, but can be up in the 60s and 70s by afternoon.

All of our rain happens in the cooler half of the year, with the heaviest amounts in November and especially in March.
