Highest temperature in Kuala Lumpur on August 10?

Platform comparison

Market context

Kuala Lumpur’s high on 10 August is being priced as a very warm, but not exceptional, tropical-afternoon outcome. Weather Underground’s own history for the city shows a typical August high around 91°F, with the record high at 96°F, while other climate references put August’s average maximum near 30–31°C and note occasional spikes into the mid-30s Celsius.[4][9][10] That makes the market’s current split between 33°C and 34°C plausible on seasonal grounds, but the 0% YES on the event-level view looks detached from the temperature range contract actually being offered: Polymarket is showing 33°C at 52% and 34°C at 44%, with the contract terms resolving to the bin containing the day’s highest observed temperature rather than a binary yes/no outcome.[13]

For comparable cases, Kuala Lumpur often finishes a few degrees above the monthly mean when convection breaks early, but rainfall and cloud cover can cap the maximum quickly. Recent history supports that range: the highest temperature over the last 15 days reached 94.9°F on 7 August, and World Meteorological Department-style district forecasts call for no rain and a maximum of 33°C for 10 August, which sits squarely between the two leading contract bins.[11][12] That forecast is consistent with recent station observations from nearby Kuala Lumpur/Subang, where temperatures have already been running in the low 30s Celsius, so traders are effectively comparing a 33°C outcome against a modest upside bias to 34°C rather than a broad tail risk.[17]

The main catalysts are the afternoon temperature peak at Kuala Lumpur International Airport Station and any late-day thunderstorm development that suppresses heating before the settlement window closes at 12:00 UTC, which is 8:00 pm local time. Time and Date’s forecast for the city still shows isolated thunderstorms and a high near 89°F, while the Malaysian Meteorological Department is calling for a dry day in the district, so the practical watchpoint is whether cloud build-up or precipitation arrives before the day’s maximum is set.[18][12] Because the market resolves from Weather Underground’s Daily Observations table, the trader-relevant data point is the highest actual station reading posted there, not the summary “Day High & Low” figure if the two differ.[4]

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 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.

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 Best Prediction Markets 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.
