The northern parts of the Austrian province Burgenland, especially the part called Seewinkel has a unique climate in Austria. The average annual precipitation, with 600mm, is far less than in other regions of the country. On the other hand, the temperatures can range from up to almost 40°C in summer to -20°C in winter. The Atlantic current's influence is minimal; the climate is Pannonic, slightly continental.
Instead of the typical Central-European main precipitation period during summer, there are 2-3 heavy rain periods throughout the rest of the year. Due to an average temperature of 10°C minimum and an average of 61 summer days warmer than 25°C, this is the warmest region in Austria.
From October to March temperatures can fall below 0°C but sometimes winter days can be exceptionally warm with no frost and temperatures up to 17°C.
In the immediate vicinity of the lake, the moderating influence of this large body of water is perceptible. Especially from the northwest, direction of the prevailing winds, the shallow waters of the lake cool off during the night, releasing heat and humidity to the Seewinkel area, thereby helping to extend the growing period to a full 250 days. There are hardly any late frosts in spring, constant temperatures in summer, and the late summer lasts longer than in any other part of Austria.
The summer months are hot and dry; many types of vegetation lie dormant during this period and begin a second growth phase in autumn. The combined effect of little rainfall, high temperatures, low humidity and continuous wind causes such rapid evaporation in summer and autumn, that at times truly semi-arid conditions prevail. Thus a perfect habitat for heat and dryness-loving animals and plant species is formed. Winter normally brings little snow and fog, and the lake freezes over for not more than 100 days, if at all.
The eastern shore of the Neusiedler See is one of the windiest regions of the European inland. In addition to the nearly constant north-west wind, dry south-east winds arise frequently. Springtime is the windiest season. In the past, there were a lot of windmills along the northern, eastern and southern shore, but only the one in Podersdorf/See that was renovated in 2001 still remains.
