I don't have a specific answer, but rather a general suggestion: weatherspark is a site with pretty thorough climate data. It shows average high and low temperature and humidity throughout the year, as well as 10/25/75/90 percentiles for each. Also does wind and precipitation. I miss their old weather dashboard like crazy, but the climate data is still good.
