Climate Chart of Bratislava, Slovakia

Climate overview

Temperature

Monthly mean temperatures reach their recorded high in July at 22.6 °C and their low in January at 0.9 °C. These are averages for each calendar month, not daytime highs or lows, so they describe the broad temperature baseline rather than the range visitors may experience from day to day. The unweighted mean across the monthly means is 11.6 °C; it is a summary of the calendar-month averages, not a day-weighted annual average. The contrast between the monthly extrema is useful context when considering how much the typical temperature baseline changes across the year.

Rain

Mean daily rainfall is highest in May at 2.52 mm/day and lowest in March at 0.77 mm/day. These are daily mean amounts for the respective months, not monthly rainfall totals, and they do not reveal how often rain falls or whether a particular day will be wet. The unweighted mean of the monthly daily-rainfall means is 1.62 mm/day. It offers a broad summary across the calendar months, but should not be read as a forecast or as a measure of rainfall frequency.

Sunshine

Mean daily sunshine reaches its highest monthly value in July at 12.33 hours/day, while the lowest is in December at 3.76 hours/day. These duration averages can help set expectations for daylight outdoor planning, but sunshine duration is not the same as day length and does not guarantee clear conditions on a given day. Across the calendar months, the unweighted mean of daily sunshine values is 8.08 hours/day. This is a summary of monthly averages rather than a promise of uniform sunshine throughout the year.

Snow

Mean daily snowfall is highest in January at 3.90 mm/day. The unweighted mean across monthly daily-snowfall means is 0.93 mm/day; these amounts do not establish how many days have snow, snow depth, snow cover, or whether conditions suit skiing.
