Highest temperature in Wellington on July 25?

Platform comparison

Market context

Wellington's highest temperature on 25 July 2026 will be measured at the international airport weather station and resolved against historical records from Wunderground. July falls within Wellington's winter season in the Southern Hemisphere, when daytime highs typically range between 10–13°C, though occasional warm northerly winds can push temperatures several degrees higher. The 0% crowd probability suggests traders expect the market's upper temperature thresholds to remain unmet, reflecting baseline winter conditions rather than anomalous heat.

Historical July data from Wellington Airport shows that temperatures exceeding 15°C on a single day are uncommon but not unprecedented during winter months. The station's records indicate that warm-air intrusions from the north occur sporadically, particularly when anticyclonic systems stall over the lower North Island. Comparable July days in recent decades have occasionally reached 16–18°C when such systems align, though sustained heat remains rare. The current zero probability implies traders are discounting scenarios where such systems develop on that specific date.

Traders monitoring this market should track long-range weather forecasts released in late June and early July 2026, particularly from the National Institute of Water and Atmospheric Research (NIWA) and MetService, which publish extended outlooks for New Zealand. Pressure-system movements and sea-surface temperatures in the Tasman Sea will influence whether northerly flow develops. The settlement window closes at midday on 25 July, so final forecasts from 24–25 July will be most relevant to market movements.

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.

Which platform has the deepest political liquidity?

Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Election Predictions UK route into the same order book at 0% fees.

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.
