Highest temperature in Wellington on July 15?

Platform comparison

Market context

Wellington’s highest temperature on 15 July 2026 will be recorded at the Wellington International Airport Station and resolved via Wunderground’s daily history data. The market currently shows a 0% crowd-implied probability for a “YES” outcome, which in this binary framing likely reflects confusion over the market’s actual multi-outcome structure, as the frontrunner is 12°C at 47%, matched closely by 13°C at 47%[1]. This near-even split between two adjacent degrees mirrors how weather markets often cluster around median historical values when no extreme forecast dominates, similar to how Eurovision’s 50/50 jury-televote split produces tight, contested outcomes rather than clear winners.

Historically, mid-July in Wellington sees average highs near 12–13°C, with extremes rarely dipping below 8°C or exceeding 16°C unless a rare southerly surge or coastal inversion occurs. The 47% probabilities for both 12°C and 13°C suggest the crowd views these as the most statistically plausible outcomes, consistent with long-term climate normals for NZWN. Traders should monitor the Bureau of Meteorology’s 72-hour forecast for NZWN, any sudden shifts in the Tasman Sea pressure gradient, and Wunderground’s real-time hourly updates as the day progresses, since settlement depends solely on the single highest recorded temperature across all times on 15 July. No major announcements or scheduled events are expected to influence temperature, making this a pure weather-dependent resolution.

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.

How accurate are award predictions?

Variable. Industry-predictable awards (Oscar Best Picture) have high market accuracy (Brier ~0.15). Reality-TV outcomes with small markets carry more noise. Eurovision is notorious for market upsets due to bloc voting.

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.
