Highest temperature in Dallas on June 28?

Platform comparison

Market context

Dallas on 28 June 2026 is forecast to hit 97°F under sunny skies, with recent records showing a consistent pattern of extreme heat in the region[2]. Historical data for this date reveals an all-time high of 110°F recorded in 1980, though typical June highs in Dallas Love Field range between 96°F and 100°F[3][5]. The current crowd-implied probability of 0% for any outcome above the expected range appears inconsistent with both the seasonal baseline and the immediate forecast, suggesting a potential mispricing in the market[2][5].

Traders should monitor real-time updates from Wunderground, the official resolution source, for any deviations from the 97°F forecast as the settlement window closes on 28 June at 12:00 UTC[2]. While no specific weather alerts have been issued for Dallas this week, the National Weather Service notes that heat indices could reach 98°F, increasing the risk of higher recorded temperatures if cloud cover fails to develop[4][6]. Given the proximity of the settlement date and the stability of the forecast, the market’s 0% probability for higher ranges warrants scrutiny against the documented historical volatility for late June in Dallas[3][7].

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
