Highest temperature in Wellington on July 20?

Platform comparison

Market context

Wellington International Airport is currently recording a maximum of 15°C under strong south-south-westerly winds, a condition that renders any higher temperature outcome for today physically impossible. The crowd-implied probability of zero per cent reflects this immediate atmospheric reality, as the settlement window closes within hours while the station has already peaked well below typical summer thresholds.

Historical data for mid-January in Wellington shows average highs near 17°C, yet July represents the coldest month with averages dropping to roughly 10–12°C [1]. Previous prediction markets on winter extremes in New Zealand have consistently resolved to the lower end of ranges when real-time data confirms sub-15°C conditions early in the day, mirroring how Eurovision’s 50/50 jury-televote split often eliminates outliers once the public vote aligns with jury consensus on obvious facts.

Traders should monitor the final Wunderground update for NZWN before the 12:00Z cutoff, as no further announcements or schedule changes can alter the recorded maximum once the day’s peak is logged. With the settlement deadline imminent and the current temperature already fixed at 15°C, the market lacks any catalyst for volatility, leaving the zero probability as the only rational outcome based on the definitive weather record.

FAQ

Which entertainment markets are available?

Oscars / Academy Awards (Best Picture, Best Director, Best Actor/Actress), Eurovision Song Contest, Emmy Awards, Grammy Awards, Golden Globes, plus reality-TV outcomes (Bachelor, Survivor). Volume usually sits in the five- to six-figure range per market.

When do award markets resolve?

After the official announcement — e.g. Oscars ceremony end for Academy Awards markets, Eurovision final end for ESC markets. UMA Optimistic Oracle typically uses the official award website as the resolution source.

What was the top Oscar 2025 market?

Best Picture, with ~$2.8M volume on Polymarket. "Anora" started as an underdog at ~8% and closed at ~62% before the ceremony — the biggest single Oscar market swing since 2019.

How are reality-TV outcomes verified?

UMA Oracle uses the official show website or producer statement as the resolution source. Very narrowly defined markets (e.g. "Will X be voted off the island?") rely on the official show notes.

Is entertainment trading worth the effort?

Niche, but lucrative for experts. Award markets have fewer informed traders than political markets; combining industry expertise (film, music) with active research often surfaces mispricings. Volume cap: large bets move the market.
