Highest temperature in Taipei on July 27?

Platform comparison

Market context

Taipei will experience peak summer heat on 27 July 2026, with the highest temperature recorded at Songshan Airport Station determining the settlement outcome. Historical July data for Taipei shows daily highs typically range between 32–35°C, though extreme heat waves have pushed readings above 37°C in recent years. The 0% crowd probability suggests traders are either awaiting clearer seasonal forecasts or treating this as a placeholder market pending visibility into atmospheric conditions months ahead.

Comparable weather markets across platforms reveal divergent liquidity patterns. Kalshi's weather contracts typically attract modest volume until two weeks before settlement, whilst Polymarket's temperature ranges often see earlier positioning as international traders hedge against Asian climate volatility. Betfair's historical temperature markets show that July Taipei highs above 36°C resolve roughly 30–40% of the time, a baseline useful for calibrating current odds. Fee structures matter here: Kalshi's flat 2% taker fee and Polymarket's variable 2–5% structure create different break-even thresholds for range bets, particularly on tight 1–2°C bands.

Traders should monitor Taiwan's Central Weather Administration forecasts from mid-July onwards, which typically issue 14-day outlooks identifying heat dome positioning. La Niña or El Niño phase transitions, tracked by NOAA, influence Pacific pressure systems affecting Taiwan's summer temperatures. Typhoon activity in late June or early July could suppress peak temperatures by introducing cloud cover and precipitation, a catalyst that would shift probability mass toward lower ranges. Resolution hinges on Wunderground's historical data feed for Songshan Airport, so confirming that source's operational status before settlement window closure remains essential.
