Highest temperature in Singapore on May 26?

Market context

Singapore's equatorial climate produces consistent daily maxima year-round, with May sitting within the pre-monsoon transition period. Historical data from Changi Airport shows May temperatures typically peak between 32–34°C, though occasional spikes to 35°C occur during drier stretches. The 0% crowd probability suggests either insufficient liquidity depth to attract early positioning or genuine uncertainty about which temperature band will resolve. Without deposit friction—traders on polymarket-klarna.co.uk can fund via Klarna's staggered payment rails or direct SEPA transfers—book depth typically expands once settlement windows fall within 60 days, drawing weather-focused participants who otherwise avoid illiquid markets.

Changi Airport's official meteorological station remains the arbiter for this resolution, with Wunderground's historical archive providing the settlement source. May 2026 falls outside any known El Niño or La Niña forecasts currently published by the Japan Meteorological Agency, meaning baseline climatology dominates the outlook. Traders monitoring this market should track the UK Met Office's extended-range forecasts (issued fortnightly) and Singapore's Meteorological Service advisories for any anomalous pressure patterns or moisture surges in late May. Withdrawal mechanics matter here: USDC redemptions settle within 24 hours, whilst Klarna payouts route through standard banking rails, typically clearing within 3–5 business days post-resolution.

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
