Highest temperature in Kuala Lumpur on July 19?

Platform comparison

Market context

Kuala Lumpur's daily maximum temperature on 19 July 2026 will be recorded at the airport weather station and resolved against historical Wunderground data. The settlement window closes at midday UTC, meaning traders have access to the full 24-hour temperature record before resolution. For programmatic traders, the key is automating a check against Wunderground's historical archive at WMKK (the airport's WMO code) once the day concludes, since manual lookups introduce timing risk near the cutoff.

July in Kuala Lumpur consistently records highs between 32–34°C, with occasional peaks above 35°C during drier spells. The 0% crowd probability suggests either extreme confidence in a specific range or minimal trading activity. Historical data from the past five years shows that temperatures exceeding 36°C occur roughly once per decade at this station, whilst readings below 31°C are exceptionally rare in mid-July. Traders should cross-reference Wunderground against the Malaysian Meteorological Department's official records to validate any edge in range selection.

Monsoon patterns and local convection drive daily variance more than seasonal shifts at this latitude. The Southwest Monsoon typically peaks in June, so by mid-July conditions stabilise towards typical heat-and-humidity patterns. Conditional order logic could trigger on real-time weather alerts from regional forecasters, though the airport station's microclimate—influenced by tarmac and infrastructure—often runs 1–2°C warmer than surrounding areas. Traders should account for this systematic bias when evaluating historical comparables.

FAQ

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi Fees 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.
