Lowest temperature in Hong Kong on August 17?

Platform comparison

Market context

On 17 August 2026, the Hong Kong Observatory will record the lowest temperature for that day in degrees Celsius. This market resolves based on the official "Absolute Daily Min" figure published in the Observatory's Daily Extract, measured to one decimal place. The settlement window closes at 12:00 UTC on that date, though resolution cannot occur until the Observatory publishes verified data, typically within days of the observation period.

Hong Kong's August temperatures are historically constrained by tropical monsoon conditions. Daily minima in mid-August typically range between 25.0°C and 27.5°C, with the Observatory's 30-year climate normal for August showing an average daily minimum around 26.1°C. Extreme lows below 24°C are rare in this month; the lowest August minimum on record is 20.3°C (August 1977). The 0% crowd probability reflects the market's current state rather than meteorological likelihood—such low-probability outcomes are common in weather prediction markets before sufficient trading activity establishes consensus.

Traders should monitor the Hong Kong Observatory's seasonal forecasts and the Western Pacific typhoon season outlook, as tropical cyclone activity can suppress temperatures significantly. The market's accessibility depends on regulatory jurisdiction: under German GlüStV rules, prediction markets require licensing; US CFTC oversight applies to derivatives on weather indices but typically exempts non-leveraged binary outcomes under certain conditions. Platforms offering no-KYC access up to $1,500 USD typically operate under safe-harbour provisions for small-stake prediction markets, though this market's actual accessibility will depend on the operator's compliance framework and user location.

FAQ

Do I need to KYC for Is Kalshi Legit?

Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.

How are winnings taxed?

Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Is Kalshi Legit 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.

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.

Is there a withdrawal cap?

No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).
