Highest temperature in NYC on July 10?

Platform comparison

Market context

New York City is currently enduring an extreme heatwave, with LaGuardia Airport recording its highest midnight temperature on record at 94°F early Friday, while daily highs have surged to 104°F, surpassing even Phoenix [1][5]. This intense thermal activity frames the current 0% crowd-implied probability for the market, as historical data shows LaGuardia’s absolute record stands at 107°F, yet July 10 specifically has not previously breached the 100°F threshold in recent almanacs [10]. The prevailing heat suggests that a temperature exceeding 100°F is plausible, but the market’s zero probability likely reflects a lack of specific forecast models predicting a peak on this exact date rather than an absence of heat risk generally.

Traders should monitor the National Weather Service’s updated forecasts for the East Coast, which currently project daily highs in the 73°F to 91°F range for mid-July, though the current heatwave has already exceeded these averages significantly [2][8]. The primary catalyst is the persistence of the heat dome; if the current trend of 100°F+ readings continues through the weekend, the probability of a 100°F+ peak on July 10 could shift rapidly from zero. Watch for any official announcements regarding the heatwave’s duration from Fox Weather or AccuWeather, as the settlement relies strictly on the highest temperature recorded at LaGuardia on that specific day, and the current record-breaking midnight temperatures indicate the atmosphere remains primed for extreme daytime peaks [4][6].

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.

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.

How fast do sports winnings settle?

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.
