The greatest amount of precipitation falls in late autumn and early winter. November is the wettest month with an average figure of 9 mm, followed by December (8 mm) and January (6 mm). Considering that average and minimum temperatures in January (average 1.6°C, min. -2.0°C), December (average 3.5°C, min. 0.1°C), and February (average 3.4°C, min. -0.9°C) drop to or below freezing, precipitation in these months can fall as snow, especially in January.

Interestingly, May, despite a moderate amount of precipitation (5 mm), stands out as the month with the highest number of wet days – a whole 19. This suggests that it rains often in May, but most likely the showers are light and short-lived.

When planning a trip to Mostar, it is important to consider the local climate so that your holiday is comfortable at any time of the year. In summer (from June to August), it is generally warm and sunny here, with the average maximum temperature potentially reaching +28°C. During this period, your suitcase should include light clothing made of breathable fabrics, a hat for sun protection, sunglasses, and sunscreen. Evenings can be a little cooler, so a light jumper or cardigan wouldn't go amiss. Regardless of the season, comfortable walking shoes are an absolutely necessary attribute, as the historic centre of Mostar with its cobbled streets is best explored on foot.

In winter (from December to February), it is quite cool in Mostar: the average temperature ranges from +1.6°C to +3.4°C, sometimes dropping below freezing. At this time, you will need warm items: sweaters, a warm jacket (preferably windproof and waterproof, as precipitation, mainly in the form of rain, is not uncommon – up to 15 rainy days per month), a hat, a scarf, and gloves. Spring (from March to May) and autumn (from September to November) are transitional seasons with changeable weather. The temperature in spring gradually rises from +5.5°C to +18.7°C, while in autumn it decreases from +16.9°C to +7.5°C. During these periods, there are often rainy days (from 10 to 19 per month), so the principle of layering in clothing will be extremely useful: t-shirts, long-sleeved shirts, a fleece jumper, and a waterproof jacket or raincoat. Don't forget an umbrella – it will come in handy at any time of the year, except, perhaps, for the driest summer months.
