Further to the reported onslaught of "deadly" hot weather in the tropics, I show here a J-shaped plot of Thai Central valley hot season death rate vs. maximum daily temperature. We note that the least deadly temperature is about 33-34. This translates to an average daily temperature of about 28-29. The death rate increases about ten percent when daily Tmax hits the upper 30s. These data are all-age, elder rates reportedly are optimum at lower temps.
When we think that many deaths occur at the end of a long lingering illness we should ask whether hot-weather induced tipping point death should be considered a heat-related death rather than in many cases a benign heat-accelerated death.
And why doesn't anyone mention the threat so close to the heart of most tropical people, namely more frequent cool weather?
