Just 4 weeks ago I was in Bordeaux with Isabelle (just 2h30 by car from here) and the temperature hit 41°C.
Today I woke up to a temperature of 2°C.
Happily it looks like that's an exception, the forecast for next week is overnight lows of 8 or 9° and highs of 16 - 18°. Definite autumnal nip in the air though...
