Climate overview

Temperature

Monthly mean temperatures are lowest in January at 0.4 °C and highest in August at 26.1 °C. This span describes average conditions for each month, not typical daytime maximum temperatures, so it should not be read as a forecast of the range visitors will experience on a given day. The unweighted mean across the monthly means is 13.5 °C. It is a compact summary of the monthly figures rather than a day-weighted annual average, and it does not indicate how temperatures fluctuate within individual months.

Rain

Mean daily rainfall is lowest in January at 0.78 mm/day and highest in July at 8.63 mm/day. These are daily averages for the respective months, not monthly rainfall totals; the lower figure does not mean rain-free days are assured, and the higher one does not show how often rain falls. The unweighted mean of the monthly daily-rainfall means is 3.40 mm/day. It offers a broad reference point, but cannot describe the timing, duration or frequency of rainfall on particular days.

Sunshine

Mean daily sunshine duration is highest in May at 9.65 hours/day and lowest in December at 6.67 hours/day. The figures can help with planning for outdoor time, but sunshine duration is not the same as day length and does not guarantee clear skies throughout a day. The unweighted mean across the monthly sunshine means is 8.14 hours/day per day. Treat it as a broad monthly-pattern summary, not a promise of the sunshine available during a particular visit.

Snow

Mean daily snowfall reaches its highest monthly value in January at 1.20 mm/day. The unweighted mean across monthly snowfall means is 0.25 mm/day per day. These averages do not establish how many days have snow, snow depth or snow cover, and they cannot indicate skiing conditions.

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

For visitors prioritising lower average rainfall, January is the conditional option in the supplied figures, with mean daily rainfall of 0.78 mm/day; this does not guarantee dry days or quantify rain frequency. Pack with the possibility of showers in mind, and use July—where mean daily rainfall is 8.63 mm/day—as a reason to give rain preparation particular attention. Those prioritising cooler monthly averages can look to January, when the monthly mean temperature is 0.4 °C. This is not a daytime low or a forecast, so check conditions close to departure and choose layers suited to variable daily weather.

For outdoor plans guided by average sunshine, May has the highest mean daily sunshine duration at 9.65 hours/day, while December has the lowest at 6.67 hours/day. These figures may help with broad scheduling, but sunshine hours are not day length and cannot promise clear conditions; keep plans flexible and bring practical protection for time outdoors. The recorded highest mean daily snowfall occurs in January at 1.20 mm/day. That average alone says neither how many snowy days to expect nor whether snow will settle, so it is not a basis for assuming snow cover or planning snow-dependent activities.
