Seoul’s climate swings between hot, humid summers and cold, dry winters. For Australian travellers, the sweet spots are spring (April–May) and autumn (September–October)—mild days, low rain, and brilliant foliage. The live forecast above gives current conditions to fine-tune your plans.
What’s the best time for Australians to visit Seoul?
Spring and autumn offer the most comfortable weather: temperatures hover around 15–25°C with low humidity. Cherry-blossom season in April is stunning but busy. Winter (December–February) brings crisp air and occasional snow – ideal for skiing or experiencing Seoul’s winter festivals. Summer (June–August) is hot and sticky, with monsoon rains in July; it’s cheaper but less comfortable if you’re not used to humidity. For a balance of comfort and value, aim for late September or early October.
What should I pack for Seoul’s weather?
Layers are your friend. In spring and autumn, pack a light jacket and long sleeves. Winter demands a warm coat, scarf, gloves, and thermal layers – temperatures can drop to –10°C. Summer calls for light, breathable clothing and a waterproof jacket for sudden downpours. Comfortable walking shoes are essential year‑round. Check the 14‑day forecast before you go, but be aware that longer‑range predictions for Seoul can shift quickly.
Does it snow in Seoul?
Yes, Seoul sees several snowfalls each winter, typically between December and February. Accumulation is usually light (5–15 cm), but it can cause travel delays. If you want a white winter, aim for January.
How humid is Seoul in summer?
Very. July averages around 80% humidity, making the heat feel far worse. If you’re used to dry heat, summer in Seoul can be draining – stick to spring or autumn for a more pleasant trip.
What’s the weather in Seoul in December?
December is cold and dry. Daytime highs hover around 2–6°C, with overnight lows well below freezing. Pack a heavy coat, hat and gloves. Snow is possible but not heavy, and sunny days are still common.
