Dewpoints are reported in most of the metars and are summarized in map form which can be animated here

Just choose temp - dew from the menu to get the map. You can get the latest reported data by hovering the mouse cursor over the individual stations

This is an extremely useful website; currently one can see that Norwich is the warmest place in the UK with around 27 deg. C.

Dewpoint is 25.7c at Howarden I think that is quite humid, but not excessive, for England in hot weather, given we are in the Atlantic Ocean.

That's way too high and certainly and not correct. The DP record is about 24C for the UK?

I would say that they need to moisten their wick - there's no way it's that high!

Weatheronline mistakes must be causing that weird reading.

There is a very uniform, regional dew of 18 C tonight.

Edit - that is humidity of around 90 percent! [dunno] Certainly feels muggy.

What the relative humidity is has nothing to do with the dew point figure though, just how close the dewpoint is to the actual temperature. If the temperature was 33C then the relative humidity would be 40% or there abouts with the same 18C dewpoint. It would still be just as humid, but feel a LOT hotter, obviously. Believe me you'd better be glad it's an 18C dewpoint and 90% RH than an 18C dewpoint and 40% RH ;)

Yes, it is better than August in NYC, that is true.

Just looking around R Brugges weather pages, and he puts data from Reading Whiteknights up there now (ie the met office reporting site)

Last year a dewpoint of 27.9c was recorded at 17:04 on the 9th of July, that must be a contender for the record, the high temp was also recorded at the same time (29.0c)

There's no way that's correct either. I managed to record a DP of 28C on my kestral hand held, but that was in Kenya a few days before the monsoon broke....... I still think the UK DP record is 'only' around 24C

[PaulKn]

Yeah, there's no way a dewpoint temperature that high occurred in Reading - perhaps the moist wick dried out.
