Highest temperature in Singapore on August 6?

Platform comparison

Market context

Singapore’s 6 August high is trading as an **underdog-to-favourite** in the **32°C** band, with the crowd implying **0% for YES** here and consensus clustered around a warm-but-not-extreme tropical outcome. In practice, that makes the market a question of whether Changi Airport reaches a solid midday/early-afternoon peak before sea breeze, cloud cover or showers cap the day’s maximum. Seasonal benchmarks support that framing: August daily highs in Singapore are typically around **30–31°C** / **86°F**, with forecasts for early August showing highs in the **mid- to high-80s °F** and lows in the upper 70s °F, which keeps the distribution concentrated rather than wide open.[1][5][20]

Historical and comparable weather cases suggest the value sits in the *middle of the board* rather than at the tails. Singapore’s August climate is persistently hot and humid, but it is also prone to brief convective showers that can blunt the absolute peak, which is why the crowd has generally leaned towards the low-30s Celsius band rather than anything notably higher.[4][13][16] On that basis, the favourite remains the most ordinary outcome — a high around **31–32°C** — while the contrarian angle is that a shower or thicker cloud early in the day could leave the top reading one notch lower than consensus expects.[2][9][14]

The main catalysts are straightforward: the timing and intensity of afternoon showers, thunderstorm formation, cloud thickness, and wind flow off the surrounding seas all matter more here than any scheduled announcement. For 6 August, nearby live-weather feeds already point to humid, cloudy conditions with some shower risk, while the broader Singapore outlook still keeps daytime maxima in the low-30s Celsius range, so traders should watch for whether the day stays bright enough long enough to realise the market’s favourite outcome.[3][12][17] The value spot is usually in judging whether the day is *a clean 32°C day* or merely *a 31°C day with brief rain interruptions*.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.

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.

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.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Who Will Win 2026 trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
