Seoul recorded a temperature of 86.7 F (30.4 C) as of September 3, up from 70.0 F (21.1 C) the previous day, according to Open-Meteo data.[^1]

The 16.7 F rise in 24 hours comes as other cities tracked by the same service showed sharp moves in the opposite direction. San Antonio, Texas, registered 83.8 F (28.8 C) on September 3, down from 100.6 F (38.1 C) on September 2, a drop of 16.8 F.[^2] Austin, Texas, recorded 84.7 F (29.3 C), down from 99.3 F (37.4 C) the day before, a fall of 14.6 F.[^3]

Dubai recorded 99.7 F (37.6 C) on September 3, up from 90.9 F (32.7 C) on September 2, a rise of 8.8 F.[^4] Los Angeles registered 66.0 F (18.9 C) on September 3, down from 81.7 F (27.6 C) the previous day, a drop of 15.7 F.[^5]

The read here is that the data shows notable one-day temperature swings in multiple cities on opposite trajectories, though Open-Meteo readings do not provide a cause for the shifts.
