The summer months delight visitors with pleasant warmth, with daytime temperatures averaging 25–26°C, especially in July and August. However, it is worth noting that the beginning of summer can be quite humid: June leads in the number of rainy days. Winter here is genuine but not too harsh, with temperatures often hovering around zero or dropping slightly below freezing, creating a cosy atmosphere.

The transitional seasons give the city a special charm. Spring arrives gradually, becoming truly warm by May, while autumn offers a mild coolness. Notably, October is one of the driest months of the year, making it an excellent time for long walks through the historical centre and exploring Romania's sights without the hassle of rain or crowds.

Climatic conditions in Cluj-Napoca are characterised by distinct seasonality, offering travellers a variety of temperature ranges throughout the year. The coldest month is traditionally January, with an average temperature of around -0.9°C and night frosts down to -4°C. On the opposite end of the scale is August, which is considered the warmest time of the year: average daily highs reach a comfortable +26°C, making the end of summer ideal for tourism.

Summer in this region of Romania can be described as moderately warm and pleasant, without the stifling heat typical of southern countries. In June, July, and August, the air warms up to an average of +23...+26°C during the day. However, travellers should be prepared for noticeable daily variations: even after a hot day, nights bring welcome coolness, when temperatures can drop to +14...+15°C. This creates excellent conditions for sleep and evening walks.

The winter period here is quite mild, but with a persistent feeling of cold. Daytime temperatures from December to February often fluctuate around zero or rise to slight positive values (+2...+5°C), while nights remain frosty. The transitional seasons — spring and autumn — pass smoothly: by April, the air warms up to +15°C during the day, and October retains remnants of summer warmth with figures around +15.5°C before giving way to the November chill.

Precipitation in Cluj-Napoca is distributed quite unevenly throughout the year, with the wettest season falling in late spring and the first half of summer. The rainiest month is June, when precipitation is recorded on average 18 days a month, and its level reaches the annual maximum. May and July are also characterised by a high probability of rain (15–16 wet days), so travellers planning a trip at this time should definitely bring an umbrella or raincoat.

The driest and most stable period arrives at the beginning of autumn. October is considered the driest month of the year: the number of rainy days drops to 8, and the volume of precipitation is minimal. August and September also delight with relatively dry weather (about 10 days with precipitation), making late summer and early autumn a favourable time for long walks around the city.

In winter, the nature of precipitation changes due to the drop in temperature. In December and January, the number of wet days rises again to 13–14 per month. Since the air temperature during this period often drops below zero (the average minimum in January is -4.1°C), instead of rain, snow often falls in Cluj-Napoca. Snowfalls create a true winter wonderland, although in terms of total moisture volume, the winter months are significantly inferior to summer downpours.

When packing for Cluj-Napoca, it is worth considering the changeability of the local weather and the features of the continental climate. The main principle when choosing a wardrobe is layering, which will allow you to feel comfortable both on cool mornings and warmer afternoons. Since exploring the city involves long walks along the cobblestones of the historical centre, be sure to bring comfortable, tried-and-tested flat shoes so your feet do not get tired by the evening.

Winters in this region of Romania can be cool, with temperatures often dropping below zero, especially at night. If your trip is planned for the period from December to February, you will need a warm jacket or down coat, a hat, a scarf, and gloves. A pair of insulated waterproof shoes will also be useful, as humidity is increased in the winter months, and precipitation in the form of snow or rain is possible.

In summer, the city is usually warm and sunny, with the air in July and August warming up to a comfortable 25–26°C. For a trip in this season, light clothes made of natural fabrics, as well as sunglasses and sunscreen, are suitable. However, it is worth remembering that the beginning of summer, especially June, is often rainy, so a compact umbrella or a light raincoat will become indispensable companions in your backpack. In the off-season, spring and autumn, the weather can change abruptly, so bring a windbreaker and a cosy jumper.
