Highest temperature in Hong Kong on June 7?

Market context

On 7 June 2026, the Hong Kong Observatory will record the day's highest temperature in degrees Celsius. This market resolves to whichever temperature band contains that official reading, published in the Observatory's Daily Extract once the date has passed and data finalised. The settlement window closes at noon UTC on that date, though resolution cannot occur until the Observatory publishes its records, typically within 24–48 hours of observation.

Hong Kong's June temperatures cluster reliably between 28 and 34 degrees Celsius, with historical daily maxima rarely exceeding 35 degrees in early June. The 0% crowd probability suggests traders expect the highest temperature to fall outside the upper threshold band this market offers—a rational position given that extreme heat events in Hong Kong typically occur later in summer, particularly July and August. Comparable June days from the past decade show most maxima settling in the 30–32 range, with outlier days reaching 33–34 degrees only occasionally. The current probability reflects baseline seasonal patterns rather than any forecast anomaly.

Traders should monitor the Hong Kong Observatory's 7-day forecast published in the days leading up to settlement, which provides wind patterns and pressure systems that drive daily maxima. The South China Sea monsoon transition in early June influences whether tropical air masses push northward, potentially raising temperatures above seasonal norms. Any tropical cyclone activity in the region—tracked by the Observatory's tropical cyclone warning system—could suppress temperatures through cloud cover and precipitation, reinforcing the low-probability outcome currently priced.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
