Showers should stay away, with a small possibility of light drizzle in the south on Monday, and although the west is expected to see the highest temperatures, a large high-pressure front should guarantee warm weather throughout the country.

There should even be a cool breeze in coastal and mountain areas to offer some relief from the heat.

Many Germans are expected to take advantage of the balmy conditions and head away for a short break, so some traffic on the roads is inevitable.

Routes heading south are expected to be busy, with the German Automobile Club (ADAC) warning of delays for those travelling to Austria, Switzerland and the Italian lakes.

Those on the way north to soak up the sun on the North Sea or Baltic coasts should fare better, but popular coastal roads may see heavy traffic, an ADAC traffic expert told The Local.

There’s better news for international travellers as many connections between Germany with eastern Europe have been improved, as have several main roads in the Czech Republic and Serbia.

The ADAC said travellers should either head off early on Saturday morning, or wait until Sunday afternoon, when the roads are expected to be at their quietest.

Whitsun vacationers should also beware of the possibility of forest fires. Although the wind is expected to drop over the weekend, a warning remains in place on account of the exceptional dryness. The alert level is current at its highest rating in Saxony and Brandenburg.

Below is a list of the routes expected to be particularly congested, according to regional newspaper the Kölner Stadt-Anzeiger:

• A 1 Köln – Bremen – Hamburg – Lübeck

• A 3 Köln – Frankfurt – Nürnberg

• A 5 Frankfurt – Karlsruhe – Basel

• A 6 Mannheim – Heilbronn – Nürnberg
