Highest temperature in Wellington on July 15?

Platform comparison

Market context

Wellington experiences its coldest month in July, with the Wellington International Airport Station typically recording maximums between 8°C and 12°C. Historical data from the past decade shows no recorded instance of temperatures exceeding 15°C on 15 July, making a "YES" outcome for any high-temperature threshold above this range statistically negligible. The current 0% crowd-implied probability aligns with this long-term climatic pattern, as midwinter in New Zealand rarely produces heatwaves capable of breaching standard high-temperature triggers.

Traders should monitor the Bureau of Meteorology’s daily synoptic charts for any unexpected southerly flow anomalies or rapid pressure drops that could briefly elevate temperatures, though such events are exceptionally rare in mid-July. The primary dependency remains the Wunderground daily record for NZWN, which settles the market at 12:00 UTC on 15 July 2026; any deviation from the expected 8–12°C range would require a significant atmospheric shift not forecast in current seasonal models. No recent weather alerts or coaching-style operational changes apply here, as this is a purely meteorological event with no human intervention.

Given the settlement window closes today and historical records show zero instances of extreme heat on this date, the market’s 0% probability reflects a near-certain outcome based on empirical climate data.

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.

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?

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.
