Market context
Wellington International Airport will record a single highest temperature on 14 July 2026, measured in degrees Celsius. The market resolves based on historical weather data from Wunderground's station records for that specific date. Current crowd pricing at 0% YES suggests traders expect the temperature to fall outside whichever range this particular option represents—likely an extreme upper bound given Wellington's winter season in July.
Wellington's July temperatures typically range between 8–13°C, with extremes rarely exceeding 15°C during the southern hemisphere winter. Historical data from the past decade shows only occasional days where the maximum temperature climbs above 14°C in mid-winter. The 0% probability reflects the seasonal baseline: unless an unusual warm front or föhn wind event occurs, the highest daily temperature will remain within typical winter bounds. Comparable July days at Wellington Airport show that temperatures above 16°C are exceptionally rare during this month.
Traders monitoring this market should track MetService New Zealand forecasts and atmospheric pressure systems developing in the Tasman Sea during early July 2026. Subtropical air masses or northwesterly flow patterns can occasionally push temperatures upward, though such events remain statistically uncommon for Wellington's winter period. The settlement window closes at 12:00 UTC on 14 July, aligning with standard meteorological day conventions. Wunderground's historical data feed provides the binding resolution source, accessible via the linked station portal with temperature unit toggles available through the settings interface.

FAQ
- Is Polymarket legal in my country?
- Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Polymarket Tax UK has a different geo footprint.
- Do I need to KYC for Polymarket Tax UK?
- Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.
- Are prediction markets gambling?
- Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.
- Is there a withdrawal cap?
- No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).
- What if regulation changes?
- If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Tax UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
