Only the info on Wikipedia but not sure on it's accuracy as the references don't seem to work for Manchester.
Getting weather data is hard work. The Met Office website should have far more information available.
Did there used to be a Manchester weather centre ?
EDIT the best I can do is: try Weatheronline and the history section , records for Manchester go way back, but you have to read off the graph. I assume August 3rd 1990 was the highest temp at Manchester Airport at 34.x
