Normals and records

Thank you very much for the climate change API, would it be possible to have a more lightweight version with aggregated data by month?

Data I believe would be interesting:

Normals for a given month (30-year period, updated every decade)
What a typical day of June looked like in this 30-year period:

  • Average Min temperature
  • Average Max temperature
  • Average Total of precipitation

Records for a given month (all time):

  • Min temperature
  • Max temperature
  • Total of precipitation

Thank you!

Edit: Link added to WMO Guidelines on the Calculation of Climate Normals

Good idea, although I would not offer all-time records like maximum temperature. This information can be very misleading.

Instead the maximum temperature of each month can be calculated and then averaged over 30 years. This should give a good indication of a typical "hot" day in a month

Yes, I was not expecting using records as an indication of maximum reachable temperature, but rather knowledge fact, associated with a datetime (example: on 2003-06-XX, temperature reached the all-time record of XX.X °C for a month of June).

But, it's not a must-have to me, I prefer having normals for max temperature and min temperature first ;)
