Market context

Seoul's weather in mid-June sits at the threshold between late spring and early summer, with the city typically experiencing warm, humid conditions as the East Asian monsoon season approaches. The highest temperature recorded at Incheon International Airport on 13 June will determine the settlement, with historical data from Wunderground serving as the authoritative source.

Incheon's June temperatures have ranged considerably over recent decades. The airport station's records show that mid-June highs typically fall between 24–28°C, though extremes have occasionally pushed toward 30°C during particularly warm years. The 0% crowd probability suggests traders are pricing in an outcome at the upper or lower bound of the settlement ranges, or uncertainty about which specific temperature bracket will materialise. Comparable June 13 observations from prior years provide the most reliable benchmark for calibrating expectations against seasonal norms and any anomalous weather patterns.

The key variable traders should monitor is the position of the North Pacific high-pressure system in early June 2026, which drives temperature patterns across the Korean peninsula. Any early arrival of the summer monsoon or blocking high-pressure ridge could elevate temperatures significantly above the seasonal median. Weather forecasts issued in the week preceding 13 June will offer the sharpest signal; traders should cross-reference multiple meteorological services, as Korean peninsula forecasting can diverge between regional models. The settlement window closes at midday UTC on 13 June, allowing only morning observations to influence final resolution.
