Highest temperature in Hong Kong on August 19?

Platform comparison

Market context

On 19 August 2026, the Hong Kong Observatory will record the day's maximum temperature in degrees Celsius, with one decimal place precision. This measurement will determine which temperature band resolves as correct. Hong Kong's August climate is characterised by hot, humid conditions during the tail end of the summer monsoon season, with daily highs typically ranging between 31°C and 34°C, though extreme heat events can push readings above 35°C.

Historical data from the Hong Kong Observatory shows that August temperatures in the territory have remained relatively stable over recent decades, with absolute daily maxima rarely exceeding 36°C. The highest August temperature on record stands at 36.3°C, recorded in 1967. August 19 specifically has seen highs cluster around 32–34°C in most years, with occasional spikes to 35°C during particularly intense heat waves. This historical consistency provides a baseline: extreme outliers above 36°C or below 31°C are statistically uncommon for this date, though not impossible given climate variability and occasional tropical storm activity that can suppress temperatures.

Traders should monitor tropical cyclone forecasts and monsoon patterns in the weeks preceding mid-August 2026, as these systems significantly influence daily maxima across Hong Kong. The Observatory publishes extended forecasts and historical climate data regularly; any unusual atmospheric patterns reported in July or early August could shift temperature expectations. Urban heat island effects and any documented changes in measurement methodology would also merit attention, though the Observatory maintains consistent protocols for temperature recording.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
