Tourist board of town Nova Gradiska

Nova Gradiska exhibits moderate continental climate, which is under the influence of the Psunj massif and partially also Babja gora. This kind of climate is characteristic of the Pannonian Plain, which takes up about 1/3 of the Croatian territory.

This means that winters in Nova Gradiska are quite cold and summers hot with quite high annual amplitudes of all climate indicators. The historical weather readings show that the average annual temperatures are quite pleasant and the mean annual temperature attains between 10,5° C and 11° C. The mean temperature in July is between 20° C and 21° C, and in January it is between -0.5° C and 1° C. This shows that the yearly amplitude of mean temperatures is not higher than 20° and 21° C. There are also years when the temperatures in the area reach extremes (more than 37° C in July and -23° C in February), with the annual amplitude being up to 60° C. In such continental conditions, the vegetation starts in the second half of March and lasts until the first half of November, thus, with optimal precipitation conditions, enabling growth of various fruits and vegetables.

Rain and snow are brought to the Pannonian Plain by western winds, and Nova Gradiska is situated in the middle of that area so that it gets an optimal amount of annual precipitation. The average annual precipitation ranges between 813 and 820 mm with some deviations in some years. The town has seen both extremely dry (precipitation 600 mm) and wet years (precipitation 1100 mm). The climate and the amount of precipitation are significantly modified and influenced by the surrounding low mountains on the north because the Psunj massif stops rainy clouds and keeps the majority of rain and snowfall. Mount Psunj has on average more than 1200 mm precipitation a year, and the hilly area of the town and the village of Cernik spreading towards the south get more precipitation than the lowlands of the Sava valley. Late spring and early summer as well as the end of the year are the periods with the heaviest rainfall (primary July maximum and secondary December maximum). Such annual precipitation rate is very suitable for agriculture.

Fogs are quite often in this type of climate, especially in the colder part of the year in the lowlands of the Sava valley and other flatter areas between the hills. Frost is also quite common and its late arrivals in spring have been known to cause great damage to fruit and vegetable growing. Winds that blow here do not have special names, and they mostly come from either the western or the northwestern quadrant.
