Highest temperature in Paris on July 16?

Platform comparison

Market context

Paris-Le Bourget Airport is expected to record its peak temperature for 16 July 2026, with the market currently pricing a 33°C outcome at 45% probability and 32°C at 33%, while the binary “YES” contract sits at 0% as it awaits resolution. On Polymarket, traders use USDC on Polygon to buy conditional tokens representing each temperature range, locking positions until the settlement window closes at 12:00 UTC on 17 July.

Historically, mid-July highs in Paris often cluster between 30°C and 35°C, with 33°C appearing frequently in recent warm spells; the current 0% crowd-implied probability for a generic “YES” outcome reflects the market’s focus on specific ranges rather than a binary pass/fail, making the 33°C frontrunner the practical benchmark for historical comparison.

Traders should monitor daily forecasts from Météo-France and real-time updates on Wunderground, which serves as the official resolution source, as sudden shifts in cloud cover or wind patterns could alter the peak reading; a recent analysis from Le Monde highlights that July 2026 has seen above-average heat across western Europe, increasing the likelihood of temperatures hitting the 33°C threshold [1].

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

What does Polymarket cost to trade?
