Climate Chart of Sofia, Bulgaria

Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023

For Sofia, Bulgaria, the climate data describe 2013–2023. Monthly mean temperatures range from January at 0.1 °C to August at 22.2 °C, giving a broad sense of the year's temperature profile without describing daytime highs or individual-day conditions. Rainfall, sunshine and recorded snowfall also vary by month, so the averages are best read as planning context rather than a forecast for any particular visit.

Climate overview

Temperature

January has the lowest monthly mean temperature, 0.1 °C, while the highest monthly mean is August at 22.2 °C. These figures describe monthly averages, not daytime maximum temperatures, and individual days can differ from the monthly pattern. Across the calendar-month means, the unweighted mean is 11.4 °C; it is a summary of those monthly means, not a day-weighted annual average.

Rain

Mean daily rainfall reaches its monthly high in June at 3.08 mm/day, and its low in February at 0.83 mm/day. The figures are daily means rather than monthly totals, so they indicate the average amount, not how often rain falls or whether a particular day will be wet. The unweighted mean across monthly daily-rainfall means is 1.74 mm/day, a broad summary that does not replace the month-by-month pattern.

Sunshine

Mean daily sunshine is highest in July at 12.88 hours/day and lowest in December at 5.64 hours/day. These averages can help frame daylight outdoor plans, but sunshine duration is not the same as day length and does not guarantee clear conditions on a given day. The unweighted mean of the monthly sunshine means is 9.03 hours/day per day, which offers an overall reference alongside the monthly extremes.

Snow

Mean daily snowfall reaches its monthly high in January at 7.05 mm/day. This recorded average does not establish how many days have snow, snow depth or snow cover, and it cannot by itself indicate skiing conditions. The unweighted mean across monthly daily-snowfall means is 2.00 mm/day; it is an average of monthly means, not a measure of snow on the ground.

Best Travel Time Guide for Sofia, Bulgaria: Ideal Seasons and Weather Insights

For visitors prioritising lower average rainfall, February is the conditional option in the supplied figures, with mean daily rainfall of 0.83 mm/day. This does not guarantee dry days or quantify rain frequency, so keep plans flexible and consider bringing rain protection; the highest mean daily rainfall is in June at 3.08 mm/day, a useful prompt to prepare for wetter conditions rather than a prediction for every day. Those who prefer cooler monthly-average conditions can use January, with a monthly mean of 0.1 °C, as a criterion when choosing dates; it is not a daytime high or a promise about daily temperatures. For outdoor sightseeing guided by sunshine averages, July has the highest mean daily sunshine at 12.88 hours/day, while December has the lowest at 5.64 hours/day. Sunshine duration is not day length, and these separate criteria do not establish one universally best time to visit.

If snowfall matters to your plans, the highest supplied mean daily snowfall is in January at 7.05 mm/day. Treat that as an average amount only: it does not show the number of snowy days, snow depth or cover, so it cannot confirm conditions for snow-dependent activities.
