One page for Duesseldorf climate: monthly averages, sourced from public APIs and refreshed automatically. Expect 1.4 C at the coldest (Jan) and 19.4 C at the warmest (Jul) — a 18.0 C spread. Expect a wet month and a dry month but no real season: 2.56 mm/day in Aug against 1.47 mm/day in Apr. Taken together that is roughly 789 mm of rain a year for the grid cell. Because each page is rebuilt independently, one unavailable upstream never takes the rest of the site down.

What the Duesseldorf climate table shows
Values are multi-decadal climatological averages for the 51.2232, 6.7793 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 2.56 mm/day in a month?
Rain is recorded as a daily mean, so 2.56 mm/day is roughly 78 mm across a 30-day month.
