One page for Cluj-Napoca climate: monthly averages, sourced from public APIs and refreshed automatically. Expect -3.0 C at the coldest (Jan) and 21.6 C at the warmest (Aug) — a 24.6 C spread. Expect a wet month and a dry month but no real season: 3.24 mm/day in Jun against 1.12 mm/day in Jan. Taken together that is roughly 678 mm of rain a year for the grid cell.

What the Cluj-Napoca climate table shows
Values are multi-decadal climatological averages for the 46.76667, 23.6 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 3.24 mm/day in a month?
Rain is recorded as a daily mean, so 3.24 mm/day is roughly 98 mm across a 30-day month.
