Climate - South Korea

Korea has a climate akin to Northern Europe, with four distinct seasons, albeit taken to further extremes at either end. Winters are predominantly dry and bitterly cold, with temperatures never much above freezing throughout December, January, and February and occasionally dipping as low as -20C. Summers by contrast are steamingly hot with long periods in the low 30s during July and August. Humidity during this period is compounded by the short-lived jangma rainy season, bringing regular heavy showers around June and July.

Like neighbours Japan and Northern China then the best months of the year to visit are during the temperate Spring and Autumn months with March/April and October/November seeing ideal temperatures and little rain. Those who time their trips especially well will see bursts of colour in the largely mountainous interior with the pinks and whites of Spring giving way to rich oranges and reds in Autumn – perfect for trekkers and photographers alike.

Due to its’ relatively compact size the above climate notes apply across the whole country, although the holiday island of Jeju – around 450km south of Seoul – is usually a couple of degrees warmer than the mainland year-round.
