Highest temperature in Dallas on July 27?

Platform comparison

Market context

On 27 July 2026, the highest temperature recorded at Dallas Love Field Station will fall into one of several defined ranges. The settlement hinges on official data from Weather Underground, which archives hourly readings from this primary National Weather Service observation point in Dallas, Texas. The 0% crowd probability suggests traders are either uncertain about range definitions or awaiting clarification on the exact bracket structure before committing capital.

Dallas summer temperatures typically peak between 95°F and 100°F in late July, with historical records showing extremes near 103°F during heat waves. The current crowd assessment reflects baseline uncertainty rather than confidence that temperatures will fall outside normal bounds. Comparable weather markets on Kalshi and Polymarket show similar early-stage liquidity patterns for July settlement dates; Kalshi's decimal odds format (1.01–1.50 range) often attracts different trader cohorts than Polymarket's percentage-based interface, particularly among those accustomed to traditional betting exchanges like Betfair. The fee structures diverge meaningfully here—Kalshi charges flat settlement fees whilst Polymarket applies percentage-based taker fees—which can shift edge calculations on low-probability outcomes.

Traders should monitor National Weather Service forecasts from mid-July onwards, particularly any heat advisories or excessive heat warnings issued for the Dallas–Fort Worth region. The Texas summer pattern typically intensifies in late July; any anomalous weather systems or upper-level ridge positioning could shift outcomes materially. Settlement occurs at 12:00 UTC on 27 July, allowing only morning readings to count, which may suppress extreme afternoon temperatures that would otherwise register.
