Weather in Daegu in August
South Korea · 20-year averages, August
A hard month. August is a hard month in Daegu, and worth planning around. The heat itself is manageable at 30.2 °C, but 84% humidity is what you will actually feel.
August ranks 9 of 12 in Daegu: past the worst of the year but short of October, which is the month to book if the dates are open.
This is wet-season rain: 16 wet days and 7 genuinely heavy ones, which in this climate means concentrated downpours rather than all-day grey. The pattern is usually a clear morning and a loud afternoon, so front-load the day and stop fighting the 3pm hour. Natural fibres and a second shirt for the day. At 84% nothing dries, including you.
What the averages hide
Averages flatten a month, and this one hides a few things: 17 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest August day reached 39.2 °C and the coldest night fell to 13.7 °C, and the wettest single day dropped 146 mm — roughly 60% of the month's rain in one day.
August is moderately variable: 68 mm in the driest year against 598 mm in the wettest, around an average of 242 mm. Roughly two Augusts in three land near that average, and the third does something else entirely.
Wind is light at 7.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 84%, high enough to notice on the warm days without dominating them.
How August sits in the year
Temperatures hold steady either side: 29.8 °C in July, 30.2 here, 25.5 in September. Nothing about the timing within the month matters much. Rain is the thing that moves: September brings 5 days less of it, so pushing the dates later buys drier weather.
Daylight in August
13.6 hours of daylight, losing 1 hours across the month. That is between Daegu's extremes of 14.6 and 9.7 hours, so days are long enough not to constrain the plan.
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
Shoulder. The value months — prices ease off and you get the place closer to itself.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
August 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 — within a degree on temperature, 1 day less rain. Gwangju is close enough to be a coin toss — within a degree on temperature, the same number of rain days.
So: August is a compromise. October is 42 points better and is what Daegu is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
