That would produce high humidity!

[CheesepuffScott]

16.7°C and 67.9mm

[Plume Meets BFTE]

A better month than july, still nothing exciting though I feel.. 16.2c and 80mm

[JeffC]

15.7 deg C and 85 mm please

[snowray]

16.1c and 71.5mm please.

[Shillitocettwo]

Drab July thus far (cooler and drier than my expectation however.....)

 

 I expect August to be truly insipid, cool, giving 2014 a run for coolness. It will fail to hit 20.C in all but SE most days with NW winds dominant, dull, damp and Atlantic in an unseasonable Polar Maritime way. 

 

So 14.6.C please and 105mm

 

  However..... I see a very slow Azores High migration and a September almost as sunny as Spring and warm with it (infact Sep 2020 will have a higher CET than any of the 3 summer months of this year).....

 

  Plenty of Summer weather in 2020, just not in *actual Summer *

[I remember Atlantic 252]

What I think too, Sept does tend to have a break from the Atlantic dominance of July and Aug
