Weather in Daegu in May
South Korea · 20-year averages, May
Prime time. May is about as good as Daegu gets. Highs average 24.7 °C, lows 11.5 °C, and rain falls on 8 days — nothing in the month is working against you.
May ranks 2 of 12 in Daegu. Only October scores clearly higher, and the difference is small enough to be settled by price rather than weather.
Rain on 8 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.
What the averages hide
The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest May day reached 36.5 °C and the coldest night fell to 1.1 °C, and the wettest single day dropped 108 mm — roughly 120% of the month's rain in one day.
May is moderately variable: 28 mm in the driest year against 218 mm in the wettest, around an average of 90 mm. Roughly two Mays in three land near that average, and the third does something else entirely.
Wind is light at 8.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 71%.
How May sits in the year
The month is on the way up: 5.9 °C warmer than April, and June adds another 3.9 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.
Daylight in May
May is at or near the longest days of Daegu's year: 14 hours of daylight, gaining 0.8 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.
An inland climate
With no coast nearby, the year swings a fair way — 36.8 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.
How busy it gets
Peak season. Expect the highest prices of the year and to be booking well ahead.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
May in Daegu versus nearby
If Daegu is one option among several, the nearby comparison is worth making. Busan is close enough to be a coin toss — 3.6 °C cooler, 1 day more rain. Gwangju is close enough to be a coin toss — within a degree on temperature, the same number of rain days.
So: May is effectively as good as it gets here — 6 points behind October, which is inside the margin where the weather stops being the deciding factor and price starts being it.
