Don't worry, it'll be 0K soon :)

@jasons47 Having moved not too far from Prague (at least not farther than 500k), I can sort of understand a little bit why it hasn't been a top priority! Thermal discomfort from high humidity and temps is nowhere near as bad over here. And it seems like they really want to focus on their niche of getting good wind forecasts for sailors and paragliders.

However I do agree that it is a big gain in useability for other users in less similar climates, for relatively little effort.

Wanted to provide some information since it looks like no one has implemented a heat index plugin here. After moving away from the Gulf Coast part of Texas I have less need to look at heat index but I definitely see why it is justified. Back when I lived there, I'd look at windy and wunderground for the forecasts.

W(eather)underground had good heat index info and good information in its line charts, windy just about everything else, especially the weather comparisons!

However, seeing that this is a feature request, I would say that only using windy for event planning in a hot and varially humid area is a bit cumbersome. This is multiply so because there is no humidity information in the rain/temperature line chart and so it remains to use the slider and manually check the values for either humidity/ dew point/wet bulb and check that the temperature is also high for this time. Note: it could be that there is a way to add to the line chart through a UI setting but I do not know of it. This contrasts with the much smoother experience of looking at a line chart.
