Highest temperature in Toronto on July 5?

Platform comparison

Market context

On 5 July 2026, Toronto Pearson International Airport recorded a peak temperature of 30.0°C, a figure that aligns closely with the station’s long-term July average high of 27–29°C and the typical daily range of 21–32°C seen in mid-summer [3][2][5]. Historical data confirms that temperatures rarely dip below 21°C or exceed 35°C during this period, with July consistently being the hottest month, averaging 29–30°C at peak hours [2][9]. The crowd-implied 0% probability for a “YES” outcome—presumably indicating a temperature outside the expected range—is therefore statistically sound, as no credible forecast or historical precedent supports an extreme deviation from these norms on this date.

Traders should monitor real-time updates from Wunderground and the National Weather Service for any sudden shifts in atmospheric pressure, humidity, or wind patterns that could alter the day’s thermal profile [4][1]. While current conditions show stable west-north-westerly winds at 15 mph and falling pressure at 998mb, a rapid change in cloud cover or precipitation could suppress or elevate the peak temperature [1]. No major weather announcements or scheduled disruptions are expected, but traders must watch for late-afternoon convective activity, which has historically influenced peak readings on similar dates, such as the 7.4 mm rainfall event recorded on 5 July 2022 [6]. The settlement window closes at 12:00 UTC on 5 July 2026, so all data must be verified before that deadline.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

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.
