Climate Chart of Graz, Austria

Climate overview

Temperature

The coolest monthly mean temperature is 0.3 °C in January, while the warmest is 21.0 °C in July. These are averages for whole months, not daytime high temperatures, so they do not show the range visitors may experience from one day or part of a day to another. Across the calendar months, the unweighted mean of the monthly temperature means is 10.6 °C. It offers a broad summary, but does not represent a day-weighted annual average or the conditions in any particular month.

Rain

Mean daily rainfall is highest in May at 3.76 mm/day, and lowest in January at 0.63 mm/day. These figures are daily means for the respective months, not monthly rainfall totals; the lower mean does not guarantee rain-free days or indicate how often rain occurs. The unweighted mean of the monthly daily-rainfall means is 2.17 mm/day. It provides an overall reference, but cannot describe the timing, intensity or frequency of rainfall on an individual visit.

Snow

Mean daily snowfall reaches its highest monthly value in February at 4.39 mm/day. This is an average amount, not a measure of snowy days, snow depth or snow cover, so it cannot establish whether snow will be present during a visit. The unweighted mean of the monthly daily-snowfall means is 1.33 mm/day. It summarizes the supplied monthly averages without indicating the frequency or duration of snowfall.

Sunshine

Mean daily sunshine reaches its high in July at 11.92 hours/day, and its low in November at 4.77 hours/day. These averages can help frame expectations for daylight outdoor plans, but sunshine duration is not the same as day length and does not guarantee clear conditions on a particular day. The unweighted mean of the monthly daily-sunshine means is 8.19 hours/day, a broad summary rather than a forecast for any specific date.
