Precipitation in Banja Luka is distributed fairly evenly throughout the year, yet distinct periods of high humidity do exist. In winter, especially in December and January, precipitation is frequently observed: due to temperatures dropping below zero, rain often turns into snowfall. These months record about 12–13 days with precipitation, so warm clothing and reliable footwear will be necessary for travellers.

The wettest period is late spring and early summer. The peak occurs in May, when precipitation can fall on up to 17 days of the month, making it the wettest month of the year. In June, rains are also frequent (about 14 days), but thanks to rising temperatures, they often take the form of summer showers which can quickly be replaced by sunshine.

The most comfortable time for those who prefer dry weather will be early autumn and late summer. October is considered the driest month, when the number of rainy days drops to a minimum (only about 7 days). Relatively little rain also falls in August, making this period favourable for long walks and exploring the sights of Bosnia and Herzegovina.

The climate in Banja Luka is moderate continental, so the contents of your suitcase will depend directly on the time of year. For a winter trip (from December to February), be sure to take a warm jacket, a hat, and gloves, as the temperature often stays around zero or drops slightly lower. Summer is usually warm here, with average highs of around +28°C, so light clothing made from natural fabrics, headwear, and sunscreen will be essential.

Spring and autumn are distinguished by their changeable character, and here the best solution is the principle of layering your clothes. This will allow you to feel comfortable both on cool mornings and during warm days. Note that May is often the rainiest month of the year (up to 17 days with precipitation), so a reliable umbrella or a compact raincoat are mandatory companions for a tourist during this period. Waterproof shoes will also be an excellent choice for the transitional seasons.

For long walks around the city and its surroundings, give preference to comfortable flat-soled shoes in which your feet will not get tired. Even if you are travelling in summer, it is worth bringing a light sweater or windbreaker for evening strolls when the heat subsides. Such an approach to packing guarantees that no weather surprises will spoil your experience of this city.
