Temperature is absolutely a problem. Without getting too deeply technical, a heat index above 99F/37C is dangerous even for healthy adults. Las Vegas this week has seen temperatures up to 120F. The forecast today is for a temperature high of 118F/48C (low of 90F/32C overnight), with a relative humidity of 8%. That works out to be a heat index of 111F/44C.
Where I am, today’s high will be 82F, but humidity is sitting at 90%, which is a heat index of 92F.
You can also look at wet bulb temperatures; at a certain point, your body can’t cool fast enough through evaporative cooling, and you’ll die from heat.
I lived through dry summers around 40°C without ACs without a problem my whole 40+ years of life. But 30°C with a high humidity is a different thing. Much comes down to being accustomed to things though naturally. I have friends who grew up in southern China who get problems when the heat is dry.
But people live in areas that get 35+°C every year for several month since the beginning of humanity itself.
