Tropical Nights in the Czech Republic: Night-time Temperatures No Longer Fall Below 20°C in Many Areas

As the prolonged spell of hot weather continues, nights across the Czech Republic are also becoming increasingly warmer. In many regions, temperatures are no longer falling below 20°C, even overnight.

With the ongoing heatwave, nights are becoming warmer as well. Meteorologists do not rule out the possibility that the Czech record for the warmest night could be broken early next week.

Alongside the high daytime temperatures, the Czech Republic is currently experiencing exceptionally warm nights. As very warm air continues to flow in from the south-west, the number of places where temperatures do not fall below 20°C overnight – so-called tropical nights – is increasing.

According to the Czech Hydrometeorological Institute (ČHMÚ), these conditions were recorded at around 20 per cent of its weather stations during the past night. Tropical nights occurred across almost the entire country, from lowland areas to higher elevations and, in isolated cases, even in the mountains. Almost all regions, as well as major cities, were affected.

The warmest night was recorded in central Prague. At the Klementinum weather station, the temperature did not fall below 23.7°C.

The current Czech record for the warmest night dates back to 8 August 2013. On that occasion, the temperature in Bystřice pod Hostýnem did not fall below 27.2°C between 9 p.m. and 6 a.m.

Meteorologists expect night-time temperatures to increase further over the coming nights. Overnight into Sunday, minimum temperatures are forecast to range mostly between 18°C and 23°C. Due to strengthening southerly winds in Moravia, temperatures in some areas could even remain above 25°C throughout the entire night.

The peak of the tropical nights is expected overnight into Monday. Ahead of an approaching cold front, cloud cover will increase, while overnight temperatures are forecast to range mostly between 19°C and 24°C. If several favourable factors coincide, the ČHMÚ believes that the current Czech record for the warmest night could even be broken.
