Pronóstico: Highest temperature in Seoul on July 31?

Platform comparison

Market context

Seoul’s late-July heat is usually strong enough that the market only needs a modestly hot afternoon to land in a higher temperature band, but the current setup still leaves a clear gap between an ordinary warm day and an outright extreme reading. The July climate baseline is around an 85°F average high, with daily highs typically sitting in the low-to-mid 80s Fahrenheit and occasionally pushing into the low 90s.[1][12] That makes a zero-centred crowd view understandable only if traders are treating the contract as requiring a genuinely exceptional spike rather than a standard summer maximum.[1][12]

The more relevant comparison is the current forecast and regional heat pattern. Recent outlooks show Seoul around 31°C to 34°C for end-July conditions, while national reporting says clear weather and persistent heat are keeping daytime temperatures elevated, with Seoul projected at about 34°C and little sign of meaningful rain to cap the peak.[2][8][10] The historical frame matters because July is Seoul’s warmest and often rainiest month, yet the clearest late-July days can still produce a strong maximum if cloud cover breaks early and humidity traps heat into the afternoon.[12][19]

For traders, the key catalysts are the day-of updates from the official source used for settlement, because the market resolves on the highest reading recorded at Incheon Intl Airport Station on 31 July 2026, not on citywide headlines or subjective heat perception. The main variables are whether the pre-noon forecast holds, whether any convective cloud or rain interrupts the warming cycle, and whether coastal influences at Incheon keep the airport reading below inland Seoul levels. Current short-range forecasts point to very warm, mostly dry conditions, so any downgrade in cloud cover or precipitation would matter less than an unexpected surge in midday heat.[2][8][11]

When do sports markets resolve?
