Climate Chart of Goyang, South Korea

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

Climate overview

Temperature

The coolest monthly mean is -2.7 °C in January, while the warmest is 25.4 °C in August. These are monthly mean temperatures rather than daytime highs, so they describe the average conditions across each month and do not indicate the range between day and night. The unweighted mean of the monthly means is 11.8 °C; it summarizes the calendar-month figures without weighting months by their number of days.

Rain

Mean daily rainfall reaches its highest monthly average in July at 9.71 mm/day, and its lowest in January at 0.44 mm/day. These are average daily amounts, not monthly totals, and the lower figure does not promise rain-free days or reveal how frequently rain occurs. The unweighted mean across monthly daily-rainfall averages is 3.12 mm/day, a broad summary rather than a forecast for a particular visit.

Snow

The highest monthly mean daily snowfall is 1.37 mm/day in December; the unweighted mean across the monthly figures is 0.39 mm/day. These are average daily amounts, not monthly snowfall totals. They do not establish how many days receive snow, how deep it becomes, whether snow cover persists, or whether conditions suit skiing.

Sunshine

Average daily sunshine is highest in May, at 10.03 hours/day, and lowest in November, at 6.92 hours/day. The unweighted mean of the monthly daily averages is 8.39 hours/day. These figures can help with broad outdoor-planning expectations, but sunshine duration is not the same as day length and does not guarantee clear skies on an individual day.

Best Travel Time Guide for Goyang, South Korea: Ideal Seasons and Weather Insights

For visitors prioritising lower average rainfall, January is the conditional option indicated by the lowest mean daily rainfall, 0.44 mm/day. This average does not guarantee dry weather or quantify rain frequency, so retain flexible plans and prepare for possible rain; July has the highest monthly mean daily rainfall at 9.71 mm/day, making rain preparation especially relevant when travelling then. Visitors prioritising cooler monthly mean temperatures can use January as their reference, with a mean of -2.7 °C; this is not a daytime maximum or a promise about any particular day's weather. For daylight outdoor planning, average daily sunshine is highest in May at 10.03 hours/day and lowest in November at 6.92 hours/day, but these averages do not specify day length or assure sunshine on a chosen date.

The highest monthly mean daily snowfall occurs in December at 1.37 mm/day. Treat that as an average amount rather than evidence of snowy days, snow depth or lasting cover; it cannot establish skiing conditions. Use it as a reason to check the forecast close to travel and prepare for variable conditions, not as a guarantee that snow will be present.
