Highest temperature in Helsinki on July 13?

Platform comparison

Market context

Helsinki Vantaa Airport is set to record its peak daily temperature for 13 July 2026, with the market currently pricing a 0% probability for any outcome outside the implied ranges. Historical data shows July is the warmest month in Helsinki, where daytime temperatures typically reach around 21°C, occasionally climbing higher during stable high-pressure systems [3]. The current frontrunner in the prediction market is 23°C at 47%, followed by 24°C at 22%, suggesting traders expect a day slightly warmer than the long-term average but not extreme [1].

Traders should monitor real-time weather updates from Wunderground and BBC Weather, as shifts in wind direction or cloud cover can alter the peak temperature significantly before the settlement window closes at 12:00 UTC on 13 July [2]. A south-easterly wind is currently observed at 15 mph with falling pressure, which may indicate changing conditions that could suppress or elevate the day’s maximum [2]. Since the resolution source is strictly the highest temperature recorded at Helsinki Vantaa Airport Station, any anomaly in station data or reporting delays could impact final settlement, making live monitoring essential.

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.

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?

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.
