This is the short version of Graz climate: monthly averages, with the monthly detail underneath. The gap between Jan and Jul is 22.7 C here: -1.3 C against 21.4 C. No month dominates: the wettest is Aug at 3.55 mm/day, the driest Jan at 1.02 mm/day. Taken together that is roughly 830 mm of rain a year for the grid cell. The build runs on a schedule and caches the last good response, so the numbers stay put even when the upstream API is having a bad day.

What the Graz climate table shows
Values are multi-decadal climatological averages for the 47.06733, 15.44197 grid cell, not a single year. Rain is the daily mean, so a value of 2.00 mm/day is about 60 mm across a 30-day month. Averages smooth over extremes, so use them for planning rather than for what to pack for next Tuesday.
Frequently asked questions
Why do the numbers differ from a weather app?
An app shows one location on one day. These are long-run averages, so they smooth out single hot or cold spells.
How much rain is 3.55 mm/day in a month?
Rain is recorded as a daily mean, so 3.55 mm/day is roughly 108 mm across a 30-day month.
