Highest temperature in Taipei on August 20?

Platform comparison

Market context

On 20 August 2026, the highest temperature recorded at Taipei Songshan Airport Station will fall into one of several defined ranges measured in degrees Celsius. The market currently prices all temperature outcomes at 0% YES across the board, a technical artefact reflecting the settlement window's position two years forward and the absence of historical data to anchor trader conviction. Polymarket's conditional token structure on Polygon means positions here remain illiquid until closer to resolution, with USDC collateral locked across multiple outcome branches that will collapse to a single winner once Weather Underground's Daily Observations table publishes the station's peak reading.

Taipei's August temperatures show consistent patterns: the city averages daily highs between 32–35°C during this month, with extreme heat events occasionally pushing into the 36–37°C range. Historical August records at Songshan Airport reveal that temperatures exceeding 38°C are rare but not unprecedented, occurring roughly once per decade during severe heat waves. The 0% probability across all ranges suggests traders have not yet positioned themselves, leaving the market sensitive to early-season weather forecasts and any tropical cyclone activity that might suppress peak temperatures.

Traders should monitor the East Asian monsoon patterns and tropical cyclone forecasts issued by the Central Weather Administration Taiwan from June onwards. Any official heat wave warnings or extreme weather advisories issued in the weeks preceding 20 August would likely trigger repricing. The specific reliance on Weather Underground's Daily Observations table rather than summary figures means resolution hinges on granular station data; traders familiar with Songshan Airport's historical recording practices hold an informational edge.

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.

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.

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.
