Can gourami survive in warmer temp?

I am thinking of building an outdoor aquarium in a desert vacation home where winter temp avg nice 70s but summer can be as hot as 120F day and 80s night. So potentially, water temp can be as high as mid 80s to even 90s.

I read that some anabantoids can handle fairly warm water, but how warm? BTW I intend to have plants in the tank and no direct sunlight.
 
I'm not sure any fish could handle those temps, but it's more the difference in the temp swings that are gonna do them in. Shoot swings like that would do me in lol. I mean thats almost a 40 degree swing there daily from night to day.
 
As long as the outdoor aquarium is in the shade, the Gourami should be fine. The larger the aquarium, the more stable the temps remain and I just don't see the water's temps swinging 40 degrees as quickly as dry desert air. Surround the tank with plants that provide a canopy and use floating plants in the tank itself. The biggest issue will be evaporation.
 
I don't expect the water temp to swing as wildly as the air temp. But for desert summer with day time temp around 110F and night around 80F, wouldn't it be possible for a 150g tank's water temp to stable around say 90-95F? Can the poor gourami handle an environment that warm for months?

I think so, yes.
Gouramis breath air and would not suffer from lower O2 levels that other fish would experience at elevated temps. These fish come from SE Asia (Malaysia, Vietnam, Thailand, Burma) and the natural water temps there can be just as warm.
 
If gourami can't handle it then any other fish will be in trouble.

They naturally live in warm shallow areas in a very warm region, and can breathe air if the oxygen level gets low in the water, which is the main problem with high temperatures.

If the pond is reasonably deep and not in direct sun then the temperature swings shouldn't be too bad.
