Lowest temperature in Hong Kong on July 13?

Platform comparison

Market context

Hong Kong's summer monsoon season typically delivers warm, humid conditions in mid-July, with daily minimum temperatures rarely dropping below 25°C. The lowest temperature recorded on any given day in July depends on nocturnal cooling patterns, cloud cover, and occasional tropical disturbances. The Hong Kong Observatory's official daily minimum—measured to one decimal place—serves as the binding resolution metric, with data published in their Daily Extract climate records after the settlement window closes on 13 July 2026.

Historical July minima in Hong Kong cluster between 23–26°C, with outliers below 23°C occurring only during unusual weather systems or measurement anomalies. The 0% crowd probability reflects the rarity of extreme cold in mid-summer rather than market dysfunction; traders pricing this market across Polymarket, Kalshi, Betfair and Smarkets would likely show near-identical scepticism, though decimal odds presentations on Betfair and Smarkets may obscure the vanishingly small implied probability more visibly than Polymarket's percentage format. Kalshi's binary structure and KYC requirements create a different trader composition than decentralised venues, potentially affecting liquidity depth on tail-risk outcomes.

Monitoring the Hong Kong Observatory's seasonal forecasts and any tropical cyclone alerts in early July 2026 remains essential; a significant weather system could shift probabilities materially. The Observatory publishes extended forecasts and monthly climate summaries that traders should cross-reference against historical patterns. Settlement depends entirely on official data publication; delays in the Daily Extract release would postpone resolution across all platforms.
