“Feels Like” / heat index

@adam-tanner
Hi, you can try using the Wet-bulb temperature layer (see more layer if necessary). When the wet-bulb temp is close to human body temperature the weather conditions may be hard and dangerous.

@idefix37 Thanks for pointing this out. I’ll definitely use this metric as it sounds more useful than heat index. So there’s no way for it to forecast this metric over the day in windy? It’s only for that moment in time?
-
@adam-tanner
This parameter is not shown in meteogram tables and so you can’t see its future changes along hours and days at a glance for a location. You need to play the timeline slider of the map. -
@idefix37 the more I look into this the more I’m confused. It says the wet bulb temp in The Sahara desert right now is 67 (19.5C) despite the regular temperature being 113 (45C). According to wet bulb charts that is more than safe to exercise in. That can’t be right?

@adam-tanner
47°C is really very high temperature, but at same time Relative humidity is only 7%, it is very low and so the wet bulb temperature is not high. So doing some exercise would be very hard, but not as it could be with the same temperature and high humidity.
Consider in USA 2 location at same temperature, one in a dry area and the other in a wet one, you’ll see that wet bulb temperature will be quite different and will express the temperature + humidity discomfort. -
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.
An example forecast from what looks like quite a humid place from weather underground:

@punyidea It is really perplexing why a humidex/windchill/feels-like layer has not been implemented here.
-
@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.
-
@punyidea It is also a standard feature of like every other weather app.
-
@Adam-Tanner I agree. Windy has moved away from being strictly about wind prediction since they added a lot of new layers. I love using it as a weather geek, but it beats me they don't have humidex (feels-like) and wind-chill factor as it is essential for many places in the world. Light bulb is a start, but it's not the same.
-
It would make sense especially now that Windy owns a majority stake in Meteoblue, which offers "feels like" in their map layers.

@louismg , hi, i say it again, issue layers for windhill, heat index, thw index and thsw index, (thw is temp-hum-wind) (thsw is temp-hum-solar-wind). there are formulaes issued and used by davis vantage pro weatherstations and loggers, these formulaes should easily by a math eccentric be turned into layers of interesting ''how it feels like''-intelligence at windy.
the more layers the merrier is my slogan, and that should be windies too. and lets not forget CO2 layer that shines a light of oblivion on the chemical fraternity layers at windy.
windy also , when considering the number of merchant and hobby shippers that use windy at all and any time 24/7/365, lacks an sea/freshwater ice cover layer, wouldnt it be good to be on their side too??
i hope the weather fronts will soon come too .
and that meteosat issues their newest images from their next generation satelitte soon
i also liked the idea of an algae layer in the ocean, i bet noaa or even the norwegian havforskningsinstitutet in bergen norway have some cool stuff there
but most of all on top of all the other stuff, id like to have satelitte map for free usage, just like the winter and summer map.
on beforehand thanks for your considerations, my wishes are of a humble size and manner and wont hurt a single soul among the board of directors, developers and moderators...
regards from the ever and forever grumpy old man
