Highest temperature in Seoul on July 12?

Platform comparison

Market context

Seoul is expected to face peak summer heat on 12 July 2026, with the Incheon International Airport station recording the day’s highest temperature in degrees Celsius. Historical data shows July highs in Seoul typically reach 32–35°C, rarely exceeding 37°C, though recent years have seen record-breaking spikes. In early July 2025, Seoul hit 37.7°C, the highest for that period in 117 years, while Hongcheon recorded an all-time national peak of 41.0°C later in the month [2][8]. The current 0% crowd-implied probability for any specific outcome suggests traders view extreme heat as unlikely or the market lacks sufficient liquidity to price nuanced ranges.

Traders should monitor the Korea Meteorological Administration’s daily forecasts and Wunderground’s real-time updates for the Incheon station, as sudden shifts in the North Pacific high-pressure system could push temperatures toward 36–38°C [9]. Recent news highlights that South Korea endured its second-hottest July since 1973, with average temperatures of 27.1°C and 22 consecutive “tropical nights” above 25°C in Seoul, indicating a trend of intensifying summer heat [1][7]. Any official announcement of a heatwave or tropical night streak before settlement could catalyse rapid repricing.

The market’s depth depends on funding flows through Klarna and SEPA on-ramps, as deposit friction directly impacts book liquidity. Traders using USDC withdrawal rails may face delays if settlement coincides with weekend banking closures, affecting position management. With settlement ending at 12:00 UTC on 12 July, timely access to Wunderground’s hourly data is critical for resolving disputes and ensuring accurate payouts.
