08Editor's notes
What the numbers don't tell you
March is a transition month, with afternoons around 11 °C, cold nights and the Independence Movement Day holiday on 1 March with ceremonies at Tapgol Park. Yellow dust from the Gobi and fine-dust episodes can push air quality down for a few days at a time, and masks are common. Plum and forsythia bloom late in the month, a week or two before the cherry trees, and the magnolias at Changdeokgung open in the final days.
Hotel rates begin to rise toward the April peak. The Seoul Marathon runs through the city on a Sunday in mid-March. The palaces reopen their gardens after the winter. Daylight passes twelve hours at the equinox. For the cherry blossom at Yeouido and Seokchon Lake, see April; book hotels for the first two weeks of April by January.
