Rain days are the days with at least 1 mm of rain, as a weather station counts them.

Weather read at the centre: ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. It is flagged rather than scored down, and crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

How busy it gets

Busiest in July and December; quietest in January, March and April.

The drive from each airport is the road's, from openrouteservice.org by HeiGIT: typical, not a schedule.

How far Aachen is, and what it costs, depends on where you set off from — the months above do not.

Before you go

Type C and F plugs at 230 V. Drives on the right. The currency is the Euro. No UK Foreign Office advice against travel. Everything for Germany: cost of living, languages, emergency numbers and health.

Being there

UPI, for visitors from India — Not accepted for paying here; bring a card that works abroad.
Tipping — Round up or add up to 10% in restaurants by telling the server the total as you pay. Give taxi drivers 5 to 10%.

Apps — Rides: Bolt, FreeNow, Uber. Maps: Google Maps, Apple Maps. Messages: WhatsApp.

The old town is best explored on foot and orientation signs can be found all around. Apart from the centre, Aachen at a whole is a fairly large city. More on Wikivoyage
