Yeah, Cali. Outside can easily crack 95 for a week straight, sometimes low 100s. I do have have a swamp cooler at the house that can maybe hold temps at 75-80, but the humidity with it on 24/7 is bad.

Hello, what he men't by a swamp cooler is, a $6 rope handle tub from walmart, put your fermenter in it, fill tub with cold water to level of brew inside of fermenter, then add frozen water bottles as needed to keep temps where you need, the brew will be a bit higher temp than the water temp.
I use these all the time, I live in Arizona and its 120 deg here in the summer, lots of frozen water bottles for me but it works great.
I love it when people say, go buy a freezer and a temp controller, as if we are all have extra money, try and find good a used freezer on craigs list for a reasonable price where I live, lol
I got the same answers from some of the same people when I asked about brewing in warm temps lol
THIS TOO
Also in summer I brew Saisons, I use 3724 Saison yeast, I start off pitching at around 72+ deg and ramp up temps 3 to 4 deg each day till its 84+ deg then leave it at 84+ till finished, doing this works Great with this yeast, if you try and ferment this yeast to cool temp wise, you will experience the ever so dreaded stuck fermentation, with this yeast.
When its 120 deg out, and its 85+ deg in the house with the AC going full blast to try and keep up, Its much easier fermenting a brew at 84+ degrees in the swamp cooler, than it is to try doing 64 deg ale, Saison 3724.
Also during the winter when its 30 deg out (we do not heat my brew room) I use a 1000w fish aquarium heater to keep that same swamp cooler up to 65 deg, works Great $20 at walmart.
Cheers
Hope this helps !
