Highest temperature in Hong Kong on August 14?

Platform comparison

Market context

On 14 August 2026, the Hong Kong Observatory will record the day's maximum temperature in degrees Celsius to one decimal place. This market resolves to whichever temperature band contains that official reading, with settlement occurring after the Observatory publishes its "Daily Extract" data. The 0% crowd probability suggests traders are either awaiting historical baseline data or treating August mid-summer conditions as too uncertain to price meaningfully at this distance.

Hong Kong's August temperatures cluster tightly around 32–34°C on average, with absolute daily maxima rarely exceeding 35°C even during heat waves. The Observatory's 30-year climate normal for mid-August sits at 32.2°C; extreme outliers—such as the 39.0°C recorded in July 2015—occur during rare tropical cyclone interactions or sustained high-pressure systems. Current zero probability likely reflects the market's nascent stage rather than climatic impossibility; comparable August-day markets typically see probability mass distributed across the 32–35°C bands once traders engage with seasonal norms.

Traders monitoring this market should track the Hong Kong Meteorological Department's seasonal forecasts (issued monthly) and watch for tropical cyclone activity in the Western Pacific during late July and early August 2026, as such systems can either suppress temperatures through cloud cover or elevate them via pre-storm heat. The Observatory publishes daily data within 24 hours of observation; resolution hinges entirely on that publication schedule. From a regulatory standpoint, this weather derivative falls outside German GlüStV gaming restrictions when structured as a prediction instrument, whilst US CFTC oversight applies only if cash settlement occurs on US soil. Most platforms offering this market operate under no-KYC thresholds up to $1,500 per position, meaning retail traders can access temperature markets without identity verification below that stake level.

FAQ

Is Polymarket legal in my country?

Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Is Kalshi Legal in California has a different geo footprint.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Is Kalshi Legal in California stores an email address and wallet addresses rather than a legal name. Over $1,500 lifetime volume triggers KYC, after which identity is no longer anonymous.

What happens during a tax audit?

You're responsible for documenting your trades. Is Kalshi Legal in California exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

Are prediction markets gambling?

Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.

What if regulation changes?

If regulation changes in your jurisdiction (e.g. prediction markets are banned), Is Kalshi Legal in California would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
