Czech weekly weather: Mild start gives way to a chilly Halloween weekend

Czechia will start the week with relatively mild autumn weather before a midweek change brings more cloud, occasional rain and cooler temperatures for the Halloween weekend.

Monday and Tuesday offer the best prospects for sunshine, with national highs reaching 13 and 15 degrees Celsius respectively, according to the Czech Hydrometeorological Institute (ČHMÚ).

Conditions begin changing Wednesday, Oct. 28, the public holiday marking Czechoslovakia’s independence. A cold front will bring rain or showers in places before cooler, moister air arrives from the north or northeast.

Prague’s forecast points to a similar pattern: the warmest weather early in the week, followed by mostly cloudy days and temperatures settling around 10 to 11 degrees Celsius.

The capital’s overnight temperatures are currently forecast to remain mostly between 3 and 6 degrees Celsius. Elsewhere in Czechia, ČHMÚ expects morning temperatures later in the week to range from five degrees down to freezing.

For Wednesday’s holiday outings, the national forecast allows for highs of up to 15 degrees Celsius in some locations, although Prague looks cooler. Rain will be unevenly distributed, so a local forecast will be more useful than the nationwide maximum when choosing where to spend the day.

Across Czechia, afternoon temperatures later in the week are expected to range between six and 11 degrees Celsius.

ČHMÚ forecasts considerable cloud cover with light rain or drizzle in places. Mountain areas could see mixed precipitation or snow as colder air moves in.

Monday may also bring lingering showers, particularly in the east, with snow possible at higher elevations. It should nevertheless be calmer than Sunday, which was wet and very windy.

For Halloween activities on Saturday and cemetery visits ahead of Dušičky, the current outlook favors warm layers and a waterproof outer jacket. Prague’s forecast suggests occasional light rain rather than a continuously wet weekend, but the timing remains uncertain.

Anyone heading into the mountains should check the forecast for their destination: conditions at higher elevations will differ substantially from those in Prague.

Updated national forecasts are available from ČHMÚ, alongside the institute’s Prague forecast.
