Interesting topic is can be possible first the sea temps are at the highest peak that stay to after mid month. Second is to see 40 in northern France to deliver here as home grown heat is not strong enough to deliver 38C and third very dry ground to support.
This month saw 38.1 achieved a bit later than 10th Aug 2003. It was good results but my memory now was extremely disgusted behaviour in other side full of heat haters dismissing and attacking GFS who been fully correct and target those who like summer warmth.
I really like to see 38C to happen in our life time very soon. Not sure if next month can be but with rain in France and average temps then not this time but like to see a last 30 or so before summer ends.
