Highest temperature in Hong Kong on August 5?

Platform comparison

Market context

Hong Kong is still running hot, with the latest forecast pointing to daytime highs around 33°C in the urban areas and a couple of degrees higher in the New Territories, while showers and thunderstorms are also in the mix. That keeps the key question for the close of the market on 5 August on whether cloud, rain, or a late surge of sunshine leaves the Observatory’s absolute daily maximum in the low, mid, or upper 30s.

The 0% crowd price looks out of line with the seasonal baseline. Hong Kong’s August climate is typically hot and humid, with average daytime highs near 31°C to 32°C and frequent rain, but not persistent cold conditions[10][16][18]. The Hong Kong Observatory’s seasonal outlook for July-September 2026 also leans normal to above-normal temperatures, which supports the view that a maximum in the 30s is materially more likely than an unusually cool day[6].

Traders should watch the Observatory’s short-range forecast updates and any changes in the weather regime over the next 24 hours, especially if showers clear earlier than expected or if convection intensifies. The HKO says its forecast is updated regularly through the day, and it notes unsettled weather with showers and thunderstorms in the current period, which can cap the maximum if cloud cover persists through the afternoon[9]. The market will only settle once the Hong Kong Observatory publishes the final Daily Extract for 5 August, using the “Absolute Daily Max (deg. C)” reading to one decimal place.

Methodology

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

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
