Highest temperature in Hong Kong on August 1?

Platform comparison

Market context

The outcome depends on the **Hong Kong Observatory’s** recorded daily maximum for 1 August, with settlement tied to the “Absolute Daily Max (deg. C)” in the published Daily Extract. Early August in Hong Kong is normally hot and humid, but the market is about whether the day’s peak lands in a higher band than the crowd is pricing now, not whether conditions feel uncomfortable. AccuWeather’s August 2026 outlook points to highs mostly in the **mid- to low-30s Celsius equivalent**, which is broadly consistent with a hot but not exceptional summer day in the city.[1]

Historical August readings show that Hong Kong can push well above 34°C when a strong anticyclone suppresses cloud and rain. The Observatory’s 2024 summary described the month as “exceptionally hot”, with the temperature reaching **35.4°C** on 5 August, the month’s high, while 2025 peaked at **34.4°C** on 10 August.[5][8] By contrast, the all-time August benchmark remains **36.3°C**, set on 8 August 2015.[11] That context suggests the current **0% YES** implies the market is treating an extreme heatoutcome as very unlikely, and that only a clear late-summer heat surge would materially change the pricing.

The main catalyst is the weather pattern over the next several days: traders should watch for any Observatory warnings, signs of a strengthening ridge of high pressure, and whether rain bands or tropical disturbances keep daytime heating capped. Local reporting has already pointed to a split between stormier spells and a return to late-summer heat, which is the key dependency for a high daily maximum.[14][18] In practical terms, the market will lean most heavily on the Observatory’s final Daily Extract once the day’s official data is published, rather than on intraday temperature swings or unofficial forecasts.[6]
