Olomouc, located in the Czech Republic, is characterized by a temperate continental climate. This means the city experiences four distinct seasons with significant temperature fluctuations throughout the year. Winters are quite cold, with average temperatures around freezing and occasional frosts, while summers bring pleasant warmth, perfect for strolling and sightseeing.

The summer months, especially July and August, are the warmest, with average temperatures around 19-20°C and maximum highs reaching 24°C. Winter, from December to February, brings cool weather: average temperatures range from -0.5°C to 1.3°C, and nighttime temperatures can drop below -3°C. Spring and autumn are transitional seasons with mild and gradually changing weather, offering comfortable conditions for visiting the city.

As for precipitation, it is distributed fairly evenly throughout the year, with no pronounced rainy season. The amount of rainfall is light, typically 1-3 mm per month, but the number of days with precipitation fluctuates between 9 and 14 per month. This means light rain is possible at any time of year, so travelers should be prepared for changeable weather and carry an umbrella or raincoat, especially if planning a multi-day trip.

Olomouc experiences a pronounced annual temperature cycle, typical of the Czech Republic's temperate continental climate. January is traditionally the coldest month, when the average temperature drops to -0.5°C and nighttime lows can reach -3.0°C. In contrast, the peak of warmth occurs in July and August. In August, the average temperature is 19.5°C, and daytime highs regularly rise to 24.4°C, making these the warmest months of the year.

The summer months in Olomouc, from June to August, provide residents and visitors with pleasant warmth. Daytime temperatures typically range between 22-24°C; for instance, the average maximum temperature in June is 22.9°C, while in July and August, it reaches 24.3-24.4°C. This creates comfortable conditions for walking and outdoor activities. Nights bring refreshing coolness: air temperatures drop to an average of 13-15°C (e.g., 13.0°C in June, 14.7°C in August). Such diurnal fluctuations, where the difference between daytime highs and nighttime lows is about 9-10°C, are a characteristic feature of the summer period in the region.

Winter in Olomouc, spanning from December to February, is characterized by cool and occasionally freezing weather. Average monthly temperatures hover around zero: from 0.5°C in December to -0.5°C in January and 1.3°C in February. At night, the thermometer regularly drops below freezing, reaching -3.0°C in January and -2.0°C in February. During the day, air temperatures usually stay just above the freezing point, around 2-4.6°C (e.g., 2.0°C in January, 4.6°C in February). Diurnal temperature fluctuations in winter are less pronounced than in summer, at approximately 5-7°C.

In Olomouc, precipitation is distributed relatively evenly throughout the year, with no pronounced rainy season or prolonged dry periods. The monthly amount of precipitation is low, typically ranging from 1 to 3 mm. This suggests that heavy and prolonged downpours are not characteristic of the city; rather, light or moderate precipitation should be expected.

The winter months bring the possibility of snowfall. In January, with an average temperature of about -0.5°C, and in December, when the temperature stays around 0.5°C, precipitation often falls as snow or sleet. Snow is also possible in February, but as spring approaches, it more frequently turns to rain. During other seasons—spring, summer, and autumn—precipitation falls primarily as rain. The highest monthly precipitation, about 3 mm, is recorded in May, June, August, and September.

In terms of frequency, May stands out as the month with the highest number of precipitation days—averaging 14. The "driest" months, both in terms of rainfall (just 1 mm) and the number of rainy or snowy days (about 9 days), are March and April. In other periods, such as January, June, July, August, and December, precipitation occurs about 13 days per month. Overall, it is worth being prepared for the fact that light precipitation in Olomouc is possible quite regularly, so a compact umbrella or raincoat will be a useful addition to your luggage.

When planning a trip to Olomouc, it is important to consider the changeable nature of the weather throughout the year. Regardless of the season, comfortable shoes for walking along the city's cobbled streets will be your best friend. Given that precipitation, though not heavy (1-3 mm per month), occurs quite frequently (9 to 14 days per month), a light umbrella or compact raincoat is a must. The layering principle will also come in handy, allowing you to easily adapt to temperature changes during the day, especially in transitional seasons.

For the summer months (June–August), when average temperatures hover around 19-20°C and can reach 24°C during the day, choose light clothing: t-shirts, shorts, and dresses. However, don't forget a light jacket or cardigan for cool evenings (around 13-15°C) or in case of rain. Sunscreen and a hat will also be useful for comfortable walks. In late spring (May) and early autumn (September), the weather can also be warm, but evenings may be cooler, so an extra layer will be helpful.

In winter (December–February), Olomouc can be quite cold, with average temperatures around freezing (from -0.5°C to 1.3°C) and nighttime frosts dropping to -3°C. During this time of year, you will need a warm jacket, sweaters, a hat, gloves, and a scarf. Waterproof footwear is also recommended, as precipitation may fall as snow or sleet. In transitional months such as March, April, October, and November, the weather can be unpredictable—ranging from cool (average temperature of 4.3°C in November) to moderately warm (average temperature of 8.5°C in April). Therefore, layering is especially important: a warm sweater, a mid-season jacket, and readiness for possible rain will help you stay comfortable.
