Graz, in southeastern Austria, receives around 850 mm (about 33 inches) of rain a year, more than Vienna, with a pronounced summer peak driven by convective storms that build over the surrounding hills of Styria. These storms can be intense, sometimes bringing hail that affects the region’s well-known vineyards and orchards, a recurring seasonal concern for local agriculture. The Mur river running through the city has occasionally flooded during periods of sustained heavy rain, though modern flood management has reduced this risk. Because summer storm intensity varies so much from one afternoon to the next here, radar tracking is a practical everyday tool during the warmer months. GeoSphere Austria operates the national radar network.
