Highest temperature in Wellington on July 7?

Platform comparison

Market context

Wellington faces a midwinter day on 7 July 2026, with the market pricing in near-zero chance that the highest temperature at Wellington International Airport reaches 14°C. Historical data confirms July is Wellington’s coldest month, where daily highs typically hover around 13°C (53°F), rarely exceeding 14°C or falling below 11°C [8]. The 0% YES probability aligns with this pattern, as 14°C sits at the extreme upper edge of the normal range rather than a likely outcome.

Comparable cases from recent winters show that temperatures hitting 14°C on 7 July are exceptionally rare; the region’s all-time maximum of 30.3°C occurred in summer, not midwinter [4]. Even during heatwaves, Wellington (Kelburn) has not breached 14°C in July since records began in 1927 [4]. Traders should monitor Wunderground’s daily update for NZWN at 12:00Z, the sole resolution source, and watch for any anomalous warm-air intrusions from the south, though no scheduled climate declarations or campaign-finance disclosures currently signal a shift [1]. The market leans on the absence of such catalysts, reinforcing the baseline winter expectation.

FAQ

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

Can prediction markets influence election outcomes?

Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

Which political events have the biggest volume?

US Presidential election, party nominations (DNC/RNC), Senate majorities, individual state outcomes (Pennsylvania, Michigan, Wisconsin), and major European elections. Peak markets reach $50-500M per event.
