How we score this
Each month combines weather, crowds, natural-disaster risk, hotel cost and flight cost into one rating for Seoul. Higher scores are better for typical leisure travellers from Australia.
Flight and hotel prices are not in this refresh yet — those factors are left out of the mix until the next Amadeus update.
