In winter and early spring, the number of rainy days increases slightly, but heavy and prolonged downpours are not characteristic of this region.

In Mersin, a Mediterranean type of precipitation distribution is observed with relatively dry summers and wetter winters, although the total annual rainfall is low. Snow is uncharacteristic for Mersin given the mild winter temperatures; precipitation falls predominantly in the form of rain.

The greatest amount of precipitation occurs in the winter months. Thus, January is the wettest month with an average figure of 5 mm of precipitation, followed by December with 4 mm. However, regarding the number of rainy days, the spring and early summer months stand out: in March, May, and June, there are on average 15 days with precipitation, despite the fact that the total volume of rain in these months (2-3 mm) is less than in winter. This indicates that in spring and early summer, rains can be frequent but are generally not very heavy. January and April also have a significant number of rainy days – 14 each.

The driest period in Mersin lasts from July to October. During these four months – July, August, September, and October – minimal precipitation falls, totaling only about 1 mm in each.

Thus, in summer and early autumn, the probability of encountering rainy weather in Mersin is minimal.

When packing your suitcase for a trip to Mersin, it is important to consider the city's Mediterranean climate with its hot summers and mild, wetter winters. In the summer months (June-September), when air temperatures can reach 29°C and above, the main focus should be on light, breathable clothing made from natural fabrics such as cotton and linen. Don't forget swimwear, sunglasses, a hat, and cream with a high SPF factor. Comfortable sandals or light open shoes are ideal for walking. Although there is little precipitation in summer (about 1 mm in July-September), June can have up to 15 days with light rains, so a light cover-up or a compact raincoat might come in handy.

For a winter visit (December-February), when the average temperature hovers around 5-8°C and the minimum can drop to 2°C, you will need warmer clothing. It is recommended to bring sweaters, fleece tops, jeans or thick trousers, as well as a mid-season jacket or light coat. Although there are no severe frosts, evenings can be cool. This period sees the most precipitation (4-5 mm in December-January) and has 11-14 rainy days, so waterproof shoes and an umbrella or raincoat will be very useful. In spring (March-May) and autumn (October-November), the weather is changeable: temperatures are comfortable, but the number of rainy days, especially in spring, can be significant (up to 15 days in March, May). The principle of layering in clothing will be the most successful solution here: t-shirts, long-sleeved shirts, a light jacket or cardigan that can be taken off or put on depending on the weather. Regardless of the season, comfortable walking shoes are a mandatory attribute for exploring Mersin and its surroundings.
