Market context

Seoul is entering early summer with temperatures climbing toward the monsoon season, yet the current crowd-implied probability of 0% for the highest temperature on 26 June suggests traders expect conditions to remain well below extreme heat thresholds. Historical data for late June in Seoul shows daytime highs typically ranging from 19°C to 28°C, with the average high for the month sitting at 26°C and humidity rising noticeably as the monsoon approaches [2][3]. In comparable years, late June rarely breaches 30°C before the full onset of monsoon rains, which usually begin in late June to mid-July, keeping peak temperatures manageable compared to July and August [3][5]. This pattern frames the 0% probability as a rational assessment that extreme heat is unlikely before the rainy season fully settles.

Traders should monitor the Korea Meteorological Administration’s short-range forecasts for any sudden spikes in maximum temperature, particularly the 30°C upper limit noted in recent AM readings [6]. The key catalyst leaning on this market is the timing of the monsoon onset; if rains arrive earlier than expected, temperatures will likely stay suppressed, reinforcing the 0% probability. Conversely, a delayed monsoon could allow humidity and heat to build, though historical trends suggest this is improbable before late June [3][5]. Recent news from the KMA confirms that daily highs are currently capped at 30°C, with no indication of extreme heat events imminent [6]. The market is thus leaning on the monsoon dependency as the primary determinant, with no major political or campaign-finance disclosures expected to alter weather patterns.
