Climate Chart of Dalian, China

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

Climate overview

Temperature

The monthly mean temperature is lowest in January, at -2.2 °C, and reaches its highest monthly mean in August, at 25.2 °C. These are averages for each month, not daytime highs, so they describe the broad temperature pattern rather than the range visitors may experience on individual days. The unweighted mean of the monthly means is 11.7 °C; it is not a day-weighted annual average.

Rain

Mean daily rainfall reaches its highest monthly average in August, at 4.30 mm/day, and its lowest in January, at 0.11 mm/day. These figures are daily means, not monthly totals, and the lower average does not guarantee rain-free days or indicate how often rain occurs. Across calendar-month means, the unweighted mean daily rainfall is 1.60 mm/day.

Sunshine

Mean daily sunshine duration is highest in June, at 10.54 hours/day, and lowest in December, at 6.82 hours/day. The unweighted mean of the monthly sunshine means is 8.93 hours/day. Sunshine hours describe average daily sunshine duration, not day length, so they can help with broad outdoor-planning expectations but do not promise how much sun any particular day will bring.

Snow

Mean daily snowfall reaches its highest monthly average in December, at 1.35 mm/day; the unweighted mean across the monthly means is 0.43 mm/day. These snowfall averages indicate daily amounts, not monthly totals, and cannot establish how many days have snow, how deep it becomes, or whether snow cover persists.

Best Travel Time Guide for Dalian, China: Ideal Seasons and Weather Insights

For visitors prioritising cooler monthly averages, January is the reference point, with a monthly mean temperature of -2.2 °C; this is not a daytime maximum, so it cannot describe the full range of conditions on a visit. Those prioritising lower average rainfall can consider January, when mean daily rainfall is 0.11 mm/day, while preparing for rain remains sensible because that average does not guarantee dry days or quantify rain frequency. Rain preparation is particularly relevant to August, which has the highest mean daily rainfall at 4.30 mm/day. For daylight outdoor planning, mean daily sunshine duration is highest in June at 10.54 hours/day, and lowest in December at 6.82 hours/day; these averages are not day length or a forecast for an individual date. The figures offer different criteria for choosing when to visit, rather than identifying one universally best month. Snowfall averages provide only limited guidance for winter travel: the highest mean daily snowfall is 1.35 mm/day in December. This does not tell visitors how often snow falls or whether snow cover, particular depths, or skiing conditions will be present.
