Cesky Krumlov, in South Bohemia, is the southernmost city in the Czech Republic. The country is landlocked and has a temperate continental climate with four distinct seasons and plentiful rainfall. Cesky Krumlov is generally slightly warmer than more northerly locations. It has a hilly landscape and sits on the Vltava River. This makes the area quite prone to mist and fog.
Summer, from June till August, is warm but wet. The average high temperature gets up to 21°C in June and peaks in July and August at 24°C. It can reach into the high 20s but it is rarely exceptionally hot. Night times can be rather cool, getting down to an average low of 12°C in the peak months. Rainfall levels reach their annual high in June with around 300mm of rain for the month. Rainfall then decreases but still falls frequently in quite high volume for the rest of the season. The high rainfall can be a bit much for the Vltava which has been known to flood.
While summer sees the wettest weather it is still the most popular time to visit because of the warmth. This is an ancient and beautiful city and not all of the cultural attractions require perfect weather to enjoy them. There are plenty of nice sunny days to be had despite the rain and of course that is when Cesky Krumlov is at its best and you can enjoy picnic lunches in the castle gardens or even go rafting on the river.
Autumn, from September till November, starts off pleasantly warm and cools quickly till it becomes cold. The average high temperature drops to 19°C in September, 13°C in October and 6°C. At the start of the season it is often nice and warm but by the end of September youâll definitely need a jacket. At night it gets very cool right from the start of the season with average lows dropping to 8°C, 5°C and 0°C respectively. Frosts sometimes occur in late October and are the norm throughout November. Rainfall decreases but it is still quite wet, though in November precipitation sometimes falls int he form of snow.
Winter, from December till February, is cold and quite snowy but actually the driest time of year. The average high temperature drops to 2°C in January which has an average low of -4°C. January is usually the coldest month in the year but December and February are not a great deal warmer. Even in the day it can fail to get above freezing and windy days make it feel even colder. Precipitation drops and usually falls as snow.
Spring, from March till May, swiftly heats up and sees a return of the rain. The average high temperature gets up to 8°C in March, 13°C in April and 19°C in May, so by mid May warm days are common. The average low temperature stays very cool at 0°C in March, 2°C in April and 7°C in May. Rainfall increases quite dramatically in March and again in May. The snow in the city and its surrounding hills begins to melt and this combined with the increased rainfall means the Vltava is again at risk of flooding.
