Although Humidex, 'Apparent Temperature', 'Feels Like temperature' are not included as tags here, they can be calculated in a script from recent 'outside temperature', 'wind speed', and 'relative humidity' values (using the same time selection for all). There are other derivatives that can be calculated similarly from a set of simultaneous values.
Although Humidex, 'Apparent Temperature', 'Feels Like temperature' and others listed in Current Conditions section, are not included as tags here, they can be calculated in a script from recent 'outside temperature', 'wind speed', and 'relative humidity' values (using the same time selection for all). There are other derivatives that can be calculated similarly from a set of simultaneous values. Note that Cumulus 1 and MX do not always use identical formula, and although MX added Feels Like it has changed the formula a few times.


The relevant formulae were previously included here, but since I have now discovered that Cumulus 1 and MX use different formulae, plus MX has been varying the Feels Like formula at different versions, it is now too complicated to list all formulae here, so only some are now included (using JavaScript, adjust for other languages):
The relevant formulae using JavaScript, adjust for other languages, for some of these are shown below:
