Ukraine Weather, climate and geography
Ukraine has a temperate continental climate with cold, snowy winters and warm summers. Summer is generally the best time to visit (between June and September), although it can occasionally be uncomfortably hot and many hotels do not have air conditioning. July and August are peak holiday months in Crimea and its resorts can become crowded with domestic and Russian tourists. Spring and autumn are both fairly short and both tend to be reasonably mild. The best season for trekking in the Carpathian Mountains is May and October when it is driest.
The northeast of Ukraine has the coldest winters and the Crimean peninsula has the warmest temperatures. The wettest part of Ukraine is the Carpathian Mountains region of the far west.
