Climate overview

Temperature

Monthly mean temperatures are lowest in January, at 0.3 °C, and reach their highest point in August, at 19.2 °C. The overall mean of the monthly means is 9.6 °C. These are monthly averages, not daytime highs, and they do not describe the range visitors might encounter from day to day.

Rain

Mean daily rainfall is lowest in February, at 0.76 mm/day, and highest in July, at 2.70 mm/day. Across the calendar months, the unweighted mean of those monthly daily averages is 1.51 mm/day. These daily means are not monthly totals and do not indicate how often rain falls, so even the lower-average month is no guarantee of dry weather.

Sunshine

Mean daily sunshine reaches its highest level in June, at 12.79 hours/day, and its lowest in December, at 2.26 hours/day. The unweighted mean across the monthly sunshine averages is 7.65 hours/day. Sunshine duration can help with broad outdoor planning, but it is not the same as daylight length and does not promise clear skies on a given day.

Snow

Mean daily snowfall is highest in January, at 3.91 mm/day, while the unweighted mean across monthly daily averages is 1.10 mm/day. These amounts describe averages, not the number of snowy days or the depth and persistence of snow cover, so they cannot establish conditions for snow-dependent activities.

Best Travel Time Guide for Gdansk, Poland: Ideal Seasons and Weather Insights

Visitors prioritising cooler monthly mean temperatures may prefer January, when the mean is 0.3 °C; this is a monthly average, not a guarantee of cool conditions throughout a visit. For lower average rainfall, February is the conditional option, with mean daily rainfall of 0.76 mm/day, but that figure neither guarantees dry days nor measures rain frequency. Rain preparation is especially relevant for July, when mean daily rainfall is 2.70 mm/day. This average is not a monthly total or a forecast, so packing for changeable conditions remains more useful than assuming rain will occur every day.

For planning outdoor sightseeing around sunshine averages, June has the highest mean daily sunshine duration, at 12.79 hours/day, while December has the lowest, at 2.26 hours/day. These durations can inform broad expectations but are not day-length measures or promises of sunshine. The recorded snowfall mean is highest in January, at 3.91 mm/day per day; it does not show how many snowy days to expect or whether snow cover will be present.
