Here are the average daily maxima and minima for the Barcelona area, by month. The 30-year figures are for Barcelona, from The World Weather Guide (E A Pearce & C G Smith, 1990). The figures for 1997 onwards were recorded by me at home. All in degrees Celsius.

Figures up to and including May 2001 have been corrected for a small systematic error in my old max/min thermometer (I have an electronic one now).
