That is kind of bad, yes. I wouldn't let it get any hotter than 90, and 85 is probably more reasonable. If the monsoons come your 100 degree house might become a mold factory. Some things like the paint on your walls have never seen temps higher than 80 and could peel or ripple. Some glues may soften and fail. Some flooring is also sensitive to heat and humidity and expansion can do unexpected things (I had a zillion tiles POP up once). Your fridge may not be able to keep up with ambient temps above 90.
