Highest temperature in NYC on July 3?

Platform comparison

Market context

A severe heatwave is currently gripping the Mid-Atlantic, with records falling across 21 states and peak temperatures yet to arrive for New York City. Recent data shows LaGuardia Airport hit 94°F at midnight on Friday, the highest such reading in its history, while neighbouring JFK recorded 100°F on Thursday afternoon[3][5]. This intense thermal pressure sets the stage for July 3, where the crowd-implied probability of 0% for lower temperature ranges appears to contradict the prevailing weather conditions.

Historical precedent frames this market heavily, as LaGuardia reached 107°F on exactly 3 July 1966, the highest temperature ever recorded at the station[2][7]. Current July 2026 forecasts project daily highs between 81°F and 99°F, yet the active heatwave suggests these averages may be exceeded significantly[4]. The Polymarket frontrunner for "100–101°F" at 100% probability aligns with the record-breaking trend, indicating that traders view the 0% probability for lower ranges as a mispricing given the extreme conditions[1].

Traders should monitor the National Weather Service updates for the Mid-Atlantic, as the peak of the heat is still forecast to arrive for the region[3]. Any sudden shifts in cloud cover or wind direction could alter the maximum temperature, but the current trajectory points toward sustained record highs. The settlement window ends on 12:00 UTC on 3 July 2026, requiring real-time observation of Wunderground data for LaGuardia to confirm the final outcome[2].

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.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

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.
