Highest temperature in Lucknow on July 7?

Platform comparison

Market context

The real-world event hinges on the highest temperature recorded at Chaudhary Charan Singh International Airport in Lucknow on 7 July 2026, with the market currently pricing a 0% chance for the “YES” outcome. Historical data shows July highs in Lucknow typically range from 91°F to 96°F (33°C to 35.5°C), rarely dipping below 85°F or exceeding 103°F[1]. Recent records reinforce this: on 26 June 2026, Lucknow hit 105.8°F (40.9°C), and in 2025, the city reached 47.8°C[4][6]. Even the 2024 season saw a peak of 43.4°C just days ago[5]. Given these figures, a 33°C threshold is well within normal bounds, making the 0% implied probability appear inconsistent with climatic reality.

Traders should monitor the India Meteorological Department’s daily forecasts and Wunderground’s live updates for the airport station, as these are the official resolution sources[3]. A sudden shift in monsoon onset or cloud cover could lower temperatures, but early July typically remains hot and dry. Platforms diverge sharply here: Polymarket uses decimal odds and low fees with minimal KYC, while Kalshi requires full US registration and offers implied probabilities with higher fees[2]. Betfair and Smarkets, by contrast, rely on traditional decimal odds and deeper liquidity but impose stricter identity checks. Understanding these structural differences is critical when assessing whether the 0% price reflects genuine market consensus or a platform-specific anomaly.
