Lowest temperature in Hong Kong on August 17?

Platform comparison

Market context

Hong Kong's daily minimum temperature on 17 August 2026 will be recorded by the Observatory and published in its Daily Extract climate data. The settlement window closes at midday UTC on that date, though final resolution depends on the Observatory releasing the official "Absolute Daily Min" figure, which typically appears within days of the observation period. The market currently shows 0% implied probability across all temperature bands, suggesting either insufficient liquidity or genuine uncertainty about which range will contain the actual low.

August represents Hong Kong's peak summer season, with overnight lows typically ranging between 25–27°C. Historical data from the Observatory shows that daily minima below 24°C are exceptionally rare in mid-August, occurring only during unusual weather patterns such as tropical storm passages or significant monsoon shifts. The 0% reading across all brackets likely reflects thin order books rather than market consensus that no temperature will be recorded; traders with deposit access via Klarna or SEPA rails may find value in establishing positions once book depth improves closer to the settlement date.

Monitoring the Hong Kong Observatory's seasonal forecasts and tropical cyclone alerts will be critical. Any significant weather system approaching the region in early August could shift overnight temperatures materially, particularly if it brings cloud cover or rainfall that suppresses heating. Traders should confirm deposit and withdrawal mechanics—USDC on-chain settlement or fiat rails through Klarna—before committing capital, as thin markets can experience slippage during rapid repricing around weather announcements.
