In reply to Alan Pierce:
Not the Tarn but it's currently hovering around 35° in Buis and has been for two or three weeks now, with occasional hot days of 38°. Looking at the long term forecast it's due to stay like that for at least two weeks. On the plus side, it's dry! Interestingly the same long term meteo for Millau, for example, is consistently 5 or 6° cooler than here. Still a bit warm, though...
