I am in Texas so I have somewhat similar temps. My answer is no, it is not too hot to mine BTC with ASICs. If you search for posts by me you'll see some different things I've done to deal with the heat. The biggest thing is to ensure that the miners do not ingest their own waste heat. My S9s mine happily when room temps are 40 deg C no problem. Besides airflow the latest firmware settings allow you to down-clock the miner which is very helpful in the heat.
