Landlocked in the Northern Hemisphere, the Czech Republic has a moderate and mile climate that varies throughout different regions, each climate type dependent on the sea level that accompanies each location. Simply put, the higher the location, the lower the average temperature and the higher the likelihood of rain. These conditions are also influenced by things like mountain range, latitude (the northernmost point is only 2.5 degrees further north than the southernmost), and distance from water sources. The average temperature is regularly dependent on sea level and the annual rainfall is also dependent on the same factor. The highest mountain range with steep slopes facing northwest has an average total rainfall that is greater than 1,200 millimeters. Adversely, the driest region of the Czech Republic, apart from the lowest-situated, southeast Moravia, is northwest Bohemia, a location that remains sheltered by the Krušné Mountains.
The sun tends to vary in level and height throughout the year. Winters are typically cold and summers are usually warm. December, January and February are typically the months that are most often related to winter temperatures with the coldest month being January where average monthly temperature falls below 0 °C. Precipitation during the winter is typically snow in the mountains and alternating rain and snow in the lowlands. Winter sports athletes are often attracted to the several months of snow coverage that tends to remain on the mountainsides during these months.
The autumn and spring have a revolving door of temps that quiver between the two. In addition, surprise weather temperatures are always expected within the Czech Republic. The location and the magnitude of two low pressures usually dictate this variance. Those two pressures include the Icelandic Low and the Azores High. During March, April and May, temperatures begin to rise. Snow starts to disintegrate during the mid-spring, even in the mountains, leaving a quick growth of vegetation. Because of this, Czech rivers are at their fullest in spring as the snow melts, encouraging Czech traditions.
If you are hoping for a warm visit to the area, hoping to spend your days enjoyably near the water, then you definitely want to visit during the summer months, especially since finding cooler temperatures simply means taking a trip up the mountains, where the average daily temperatures are just over 10 °C.
