Yellow dust from China can create hazy conditions 3-4 days in May, requiring masks and limiting outdoor photography

Essential Tips

What to Pack

Light layers (t-shirt + cardigan) - temperatures swing 8°C (14°F) between morning and afternoon

Waterproof light jacket - spring rains last 2-3 hours and arrive without warning

Comfortable walking shoes with grip - wet pavement from frequent light showers can be slippery

SPF 30+ sunscreen - UV index reaches 6-7 on clear days, higher than winter visitors expect

Dust mask or N95 - yellow dust from China creates hazy conditions 3-4 days per month

Portable battery pack - cool weather means more outdoor time and photo opportunities drain phones faster

Light scarf or neck covering - sea breezes around Wolmido and Songdo can feel chilly in evening

Umbrella (compact) - sudden 30-minute downpours catch tourists unprepared

Cash in small bills - many food stalls and local transport don't accept cards, need ₩1,000-5,000 notes

Insider Knowledge

Take Seoul Subway Line 1 to Incheon instead of airport buses - locals avoid weekend traffic by using the 1-hour train route that costs ₩1,370 vs ₩15,000+ for buses

Visit Sinpo International Market Tuesday-Thursday mornings when vendors restock after weekend crowds - you'll find fresher ingredients and vendors more willing to explain dishes

Download Citymapper app and add ₩10,000 to a T-money card at any station - this covers 3-4 days of local transport and works on buses, subway, and some taxis

Book accommodations near Bupyeong station rather than touristy Wolmido - rates are 40% cheaper, food options are more authentic, and you're better connected to Seoul

Avoid These Mistakes

Assuming all outdoor attractions stay open during rain - many close observation decks and boat tours when spring showers arrive, always have indoor backup plans

Not checking yellow dust forecasts on Korean weather apps - international weather services don't track this regional phenomenon that can ruin outdoor photography days

Only visiting Wolmido and missing Songdo - most tourists skip the ultra-modern district that locals consider more impressive than the traditional amusement park area
