When cherry blossoms and autumn colours actually arrive in Korea
Both seasons move across the country over several weeks rather than arriving everywhere at once — how the fronts travel, and why booking early is a gamble either way.

Blossom moves south to north, foliage moves north to south
Neither season is a date. Both are fronts that cross the peninsula over roughly two to three weeks, and where you are determines when you see it.
Cherry blossom begins in the far south — Jeju and the southern coast — and works northward, reaching Seoul noticeably later. Autumn colour does the reverse, starting in the northern mountains and descending, so the mountains turn well before the cities do.
The practical consequence is that a fixed set of dates can be too early in one part of the country and too late in another, and that a badly timed trip can often be rescued by moving rather than waiting.
Why you cannot book it precisely
Both fronts shift year to year with the weather, by enough to matter. Forecasts are published each season by the meteorological service and by tourism bodies, and they are reasonably good — but they firm up only a few weeks ahead, which is usually after flights and accommodation have become expensive.
Blossom is the more fragile of the two. Full bloom lasts only a matter of days at any one spot, and a spell of heavy rain or wind can end it early. Autumn colour holds for considerably longer and is a safer thing to plan a trip around.
If you are committing months ahead, treat either season as a strong possibility rather than a guarantee, and have a trip that is worth taking regardless.
The crowds are part of the experience
Korea's own population travels for both seasons, heavily. Famous blossom streets and well-known autumn valleys are extremely busy at peak, and accommodation near them books out and rises in price.
Weekdays are dramatically quieter than weekends at both. Early morning is quieter still, and at the well-photographed spots it is the difference between a picture and a crowd.
The less famous places are often barely attended. A provincial park during peak foliage can be near-empty on a Tuesday while a nationally known one an hour away is at capacity — which is much of the argument for looking beyond the obvious list.
Festivals attach to both
Blossom and foliage festivals run across the country and the dates are set in advance, which means they sometimes miss the actual peak. They are worth attending on their own terms — food stalls, lights, crowds in good spirits — rather than as a guarantee of the trees.
