Market context

The Hong Kong Observatory will record the single highest temperature in degrees Celsius on 16 June 2026, with settlement determined by their official daily maximum reading published in the Daily Extract. The crowd currently implies 0% probability across all temperature ranges, suggesting either extreme uncertainty or insufficient trader participation at this early stage.

Hong Kong's June climate sits firmly within the pre-monsoon season, characterised by heat and humidity ahead of the southwest monsoon onset. Historical data shows June daily maxima typically range from 29–33°C, with occasional spikes above 34°C during heat waves. The 1998 heat wave saw June temperatures exceed 35°C on multiple days, whilst more recent years (2015–2023) have generally tracked within the 30–33°C band for mid-June dates. The absence of any crowd probability suggests traders are waiting for seasonal forecasts or treating this as a placeholder market rather than engaging with the underlying meteorological patterns.

Traders should monitor the China Meteorological Administration's extended-range forecasts from May onwards, as these typically provide guidance on whether June will trend warmer or cooler than the 30-year normal. The El Niño/La Niña status heading into northern hemisphere summer will influence regional pressure patterns and thus Hong Kong's heat intensity. Any significant tropical cyclone activity in the western Pacific during early June could suppress temperatures, whilst a stable high-pressure system would favour above-average readings. The Hong Kong Observatory publishes monthly outlooks in early May that will clarify seasonal expectations before this specific date resolves.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Who Will Win, which mirrors the Polymarket order book directly.

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.
