Current predictions name temperatures up to 38 degrees Celsius (100 F) in the South of France, at least 25 degrees Celius (77 F) in the UK and temperatures of 26 - 32 degrees Celsius (79 - 90 F) for the Netherlands and Germany, possibly for 10 days in a row or more. The weather model has been wrong before, but if it's right we're in for a very early heatwave.
