The 2-1 weighting given to the dew-point was reached via much trial and error.įor example, consider three different Summertime scenarios, all typical around here (Texas): 1) a 90° day with a dew-point of 70° 2) a 102° degree day with a dew-point of 60° and 3) a “low for the day” morning 80° temperature with a dew point of 73°. I’ve also found it necessary to factor in both the dew-point and the humidity.

If there is zero humidity, then I estimate that each mile per hour has around a full degree’s worth of cooling impact. The optional wind factor includes the fact that the wind’s ability to cool the body is adversely impacted by the relative humidity and at 100%, has little if any impact. This takes a weighted (2-1) average of the dew-point and relative humidity combined with the temperature and fudges a bit for wind. “Misery Index” = (temperature☏ + ((dew-point☏ * 2) + humidity) / 3) – (windspeed-mph * (1 – (%humidity / 100))) Through a bit of trial and error over several summers and workouts with a variety of temperatures and humidities, I’ve pretty much settled on the following: I tried both these formulai over a period of time myself and found them to be pretty good, but still not always consistent. I vaguely recall that the one my grandparents listened to referred to a “misery index” that, if memory serves me correctly, was calculated by combining the temperature (Fahrenheit) and either the relative humidity or the dew-point to produce a number that, if it exceeded 150, indicated that outdoor conditions were absolutely “miserable”.

The modern “heat index”, in my opinion, overweights the temperature by being too low for conditions when the temperatures are lower and humidities higher.īack in my childhood I often spent good portions of my summers at my grandparent’s house in East Texas where we got the daily weather forecasts from TV stations in Houston. The weather service uses a “ heat index” figure that seems to be fairly accurate from a pure temperature standpoint when simply sitting outside in the shade, but I find from experience that it falls woefully short in consistently measuring the conditions one experiences when actually working out. Now that we are in the middle of the dawg daze of yet another long hot Texas Summer, I decided to share a formula that I’ve developed and honed over time to quantify just how hot it actually “feels” when attempting to do any type of physical activity outside.
