Highest temperature in Taipei on July 19?

Platform comparison

Market context

On 19 July 2026, the highest temperature recorded at Taipei Songshan Airport Station will fall into one of several defined ranges. The settlement relies on Wunderground's historical weather data for that specific station, with the crowd currently assigning zero probability to the YES outcome—a signal worth examining against Taipei's seasonal climate patterns and the mechanics of how different platforms price weather markets.

July sits at the peak of Taiwan's summer monsoon season, when Taipei routinely records daily highs between 32–36°C. Historical data from the past decade shows temperatures at Songshan Airport rarely exceed 37°C in mid-July, though heat waves can push readings higher. The 0% crowd probability suggests either the market's YES threshold is set above typical seasonal norms, or liquidity remains sparse enough that no trader has yet committed capital to test the range. Kalshi and Betfair typically see tighter spreads on weather markets with clearer historical benchmarks, whilst Polymarket's decimal-odds format can obscure implied probabilities for casual traders unfamiliar with conversion calculations.

Traders monitoring this market should track the Central Weather Administration Taiwan's seasonal forecasts and any heat-wave warnings issued in early July 2026. Humidity levels and upper-air patterns in the weeks preceding the 19th will signal whether conditions favour above-average temperatures. The settlement window closes at 12:00 UTC on 19 July, giving traders a narrow window to adjust positions once morning weather data becomes available—a constraint that affects position-sizing differently across platforms depending on their intraday liquidity profiles.
