Winter, from December to February, is cold, with average temperatures around freezing (0 °C or 32 °F) or slightly below. Cold air often stagnates in the plain, bringing cold and gray weather, with mist and fog; snowfall is quite frequent, but generally not abundant. On some occasions, however, cold air masses from Russia invade the Hungarian Plain, bringing strong winds at first and then intense frosts. In January 1987, the temperature dropped to -27 °C (-17 °F); more recently, in February 2012, it has dropped to -23 °C (-9 °F).

In spring, different situations alternate: the average temperature rises quickly, and already in March the first pleasant days may occur, but the return of wintry weather is also possible, with snow and frost in March, and more rarely in April. Clashes of different air masses can generate intense winds.
In the second half of April, the temperature can already exceed 20 °C (68 °F), and in May the first hot days can occur, with peaks around 30 °C (86 °F); on the other hand, in other situations it can still be cold in the first half of May, and more rarely in the second, at least at night. In May, thunderstorms begin to erupt in the afternoon.

Summer, from June to August, is warm and sunny. Sometimes, some Atlantic weather fronts can still affect this area, bringing cool and rainy weather. At other times there may be heat waves, with maximum temperatures rising to about 35/37 °C (95/99 °F), most likely in July and August, but typically they only last two or three days. In fine weather, afternoon thunderstorms can occur.

Autumn is initially a mild and pleasant season in September, when, however, sometimes it begins to be a little cold at night, then from October the temperature decreases rapidly, and cloudiness and rain become more frequent. November is a cold and gray month, and in the course of the month the first snowfalls may occur.


The amount of sunshine in Budapest is good in May and in summer, while it's poor or mediocre from November to February, when gray skies predominate.
