Using a humidex calculator a 30C temperature would need to have a relative humidity level of 68% to achieve a humidex of 40C. A temp of 32C would need to have a 52% RH to hit 40C
According to that, we had a humidex of 39C on 1 August 2013. Don't remember it feeling that hot, but it was humid by our standards. We had a temp of 31C with a dew point of 20C. Usually the dew point would be around 15C in those conditions.
39C is close, but what about 40C you claim happens every summer? I doubt more than just a couple such humidex readings in London over at least the last 5 years... Please correct me if I'm wrong.

Do we care? No. London isn't chicago - and thank god for that.
All I asked was when was the last time London had a 40C humidex. B87 said it happens every summer.

Does it? Apparently not.

I'm not suggesting it never happens (even though 39C isn't 40C ) but from what I gather it's not common....
Like dean york said, the humidex is a big joke. Way way over done.... Using the heat index formula, an air temp of 31C with a dew point of 20C would create a heat index of 33C
Tbh, from my experience 30c heat in the UK during july 2014 was like 40 degree heat in Grease... However I'll look around for humidex and heatindex ibn the southern English area tomz...

Yeah, but all that black leather and dance routines, it's no wonder they were hot in Grease.
It’s is interesting how cool summers in the Uk are compared to many locations in the northern hemisphere. According to wunderground the highs in London have not even been above 70 F in the last 12 days!:

Our highs have not been below 80 F all month here on the other side of the Atlantic.
From a Southern Hemisphere perspective It's more interesting how warm he UK's summer are for the latitude. If NZ latitudes extended to even the same latitude as London, it would be a miserable climate indeed,

True, but maybe due to the proximity of the continental influence from Europe helps. NZ has no large landmass anywhere near it, not to mention the huge percentage of the S. Hemisphere that is ocean compared to N. Hemisphere.

Lol, George you enjoy irritating the UK posters with constantly bringing up the cool nature of their summers. Come winter they will be laughing at you. Well not you, cause you seem to enjoy extreme cold winters, but the massive numbers of the rest of Chicagoans that board all those flights to Hawaii and Florida I saw on the news last winter. You are rare indeed. I've yet to meet a person from Chicago, or anyone that lived there, that enjoyed their winters. Most dreaded them. They are dreadful.
