Good afternoon, everyone.

Friday was the first day with temperatures over 38C for this heatwave in
some areas of the country:

Agrinio: +39.2C
Piraeus, Athens: +37.2C
Elliniko, Athens: +37.2C
N. Filadelfia, Athens: +37.0C
Larisa: +37.0C
Serres: +37.0C

Today has been hotter and I see 40C has been reached on some locations.

Yannis, SE Athens
+36.7C, 21%, SLP 1013.5 hPa (today's max +38.0C)
but breezy and comfortable

I notice that the diurnal range in Athens is quite small,
with a min of 28 and max of 34. Maybe that's not so bad, with the
strong breeze and reasonably low dewpoint. I only found one place in
Greece with 38 today, Kalamata.
