Highest temperature in Hong Kong on August 15?

Platform comparison

Market context

Hong Kong is set for another hot, humid August day, with the Observatory’s seasonal outlook for August–October calling for temperatures that are normal to above normal. That keeps the market anchored to the upper end of the usual summer range rather than an outlier spike, especially with the day’s forecast showing urban highs around 35°C and some areas a couple of degrees warmer.

For comparable framing, this is less like a binary public-vote contest and more like a late tally in a fixed-count process: the market resolves only when the official daily extract is published, so the key question is not sentiment but the final recorded “Absolute Daily Max”. In that sense, the crowd’s 0% YES reading looks like a placeholder against an event that has not yet settled, rather than a strong signal about the temperature itself. Hong Kong’s August climatology also usually sits around the low 30s, which leaves little room for a dramatic surprise unless a heat surge pushes beyond the normal band.

Traders should watch the Observatory’s daily extract release, because this market cannot resolve until the 15 August data are published and finalised. The main catalyst is the official temperature record for the day, not the intraday forecast, and the settlement source is specifically the Hong Kong Observatory’s “Absolute Daily Max (deg. C)” in the climatological record. Cloud, showers and thunderstorm timing matter only insofar as they cap or extend the daytime maximum before the observation day closes.

FAQ

Which entertainment markets are available?

Oscars / Academy Awards (Best Picture, Best Director, Best Actor/Actress), Eurovision Song Contest, Emmy Awards, Grammy Awards, Golden Globes, plus reality-TV outcomes (Bachelor, Survivor). Volume usually sits in the five- to six-figure range per market.

When do award markets resolve?

After the official announcement — e.g. Oscars ceremony end for Academy Awards markets, Eurovision final end for ESC markets. UMA Optimistic Oracle typically uses the official award website as the resolution source.

How accurate are award predictions?

Variable. Industry-predictable awards (Oscar Best Picture) have high market accuracy (Brier ~0.15). Reality-TV outcomes with small markets carry more noise. Eurovision is notorious for market upsets due to bloc voting.

Who can trade Eurovision markets?

Polymarket is globally accessible but geo-blocked in select jurisdictions — traders there use broker frontends with a different geo footprint to reach the order book. Eurovision markets have strong European liquidity; German/Austrian/Swiss flow often drives consensus.

How are reality-TV outcomes verified?

UMA Oracle uses the official show website or producer statement as the resolution source. Very narrowly defined markets (e.g. "Will X be voted off the island?") rely on the official show notes.
