Highest temperature in Singapore on July 27?

Platform comparison

Market context

Singapore’s temperature peak on 27 July is being priced as a **favourite in the low 30s Celsius**, with the crowd putting the most weight on **31°C** at 35% and **30°C** at 32%, while the attached market description says trader probabilities are concentrated around 30–32°C.[1] That leaves the current **0% YES** framing as a clear underdog in practical terms: consensus is for a modestly warm day, not a sharp heat spike, and the value question is whether the top of the range can out-run the market’s centre of gravity. In handicapper’s terms, the favourite is a mid-30s-high humidity outcome; the contrarian angle is a brief sunny break lifting the airport station a degree or two above the pack, though the market is already leaning against that.

July in Singapore is normally a wet, cloudy month, which matters because cloud cover and showers can suppress the daytime high even when humidity stays elevated.[2][4] Historical climate context from July averages shows a meaningful daily rain chance and frequent cloud, so a forecast near 30–31°C is consistent with the usual range rather than a standout hot spell.[2][4] That is why the consensus sits where it does: it is not a market expecting exceptional heat, but one expecting a fairly standard tropical afternoon. The value spot, if any, is on the tail where clouds clear long enough for a warmer-than-expected maximum.

For traders, the key catalysts are the day-of Singapore forecast updates, especially any shift in shower timing, cloud cover, or wind that changes how much sun reaches Changi Airport.[1][3] The market description also points to ongoing model consensus from the Meteorological Service Singapore, so late changes in official guidance matter more than generic seasonal averages.[1] A recent weather source is useful mainly for the broad setup: Singapore in July typically carries a substantial rain and cloud burden, which keeps the ceiling on the day’s maximum unless clearing develops at the right time.[2][4]

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 Who Will Win, 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.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Who Will Win 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.
