Highest temperature in Seoul (Incheon) on August 2?

Platform comparison

Market context

Incheon’s 2 August high is being shaped by a broad South Korean heatwave rather than a localised anomaly, with forecasters calling for daytime highs in the low to mid-30s and humidity making the air feel hotter. The current crowd pricing for a 32°C result is broadly consistent with that setup, but the market has already moved in line with official and media forecasts that keep Seoul/Incheon around 32–35°C rather than at the very top of the heat range.[1][2][3]

For historical framing, early-August temperatures in the Seoul–Incheon corridor normally sit well below the upper-30s, so a reading in the 32–33°C band would be warm but not exceptional for a peak-summer day.[12][17][19] The recent pattern matters more than the long-run average: Reuters reported South Korea’s hottest-ever reading of 41.4°C on 31 July, while KMA-linked coverage said the heatwave is expected to continue into early August, leaving little reason to expect a sharp cool-down before the settlement window closes.[11][19]

Traders should watch whether the KMA keeps Incheon in the low-30s on updated short-range forecasts, because small shifts in cloud cover, sea breeze timing, or rain can move the daily maximum by 1–2°C and change the winning range.[5][7] The most relevant catalysts are any revised morning-to-afternoon forecast bulletins, thunderstorm or shower alerts, and the actual temperature trace at Incheon Intl Airport Station, since the market settles on the highest observed value at that station rather than a city-wide estimate.[1][2]
