Jeju in March In recent years the Jeju Fire Festival at Saebyeol Oreum was held around mid March. Because of wildfire risk the hillside is no longer actually set alight, and a media-art show has taken its place. On a late-March weekend the Jeonnong-ro cherry blossom festival fills a street in central Jeju City, and canola fields start turning yellow.
Days averaged 14°C and nights 7°C, cool enough that outdoor sightseeing called for a layer. Out of 31 days, about 8 brought rain; the rest stayed dry. The driest year, 2011, had 5 rain days; the wettest, 2010, had 14.
Nights fell below 5°C on 9 days on average. The coldest night came in 2010, at −0.4°C.
How long it rained On a rainy day it rained for about 6.0 hours. Rain came at any time of day.
