Highest temperature in Wellington on July 25?

Platform comparison

Market context

Wellington's highest daily temperature on 25 July 2026 will be recorded at the airport weather station and resolved against historical data from Wunderground. July is mid-winter in New Zealand, with Wellington typically experiencing average highs around 8–9°C during this period. The 0% crowd probability suggests traders are either absent from this market or treating it as a calibration exercise; the actual resolution will depend entirely on whether conditions deviate significantly from seasonal norms.

Historical July temperatures at Wellington Airport show a range of roughly −2°C to 17°C for daily highs over the past two decades, with most days clustering between 6°C and 11°C. The market's temperature bands will determine whether a typical winter day settles in the lower ranges or whether an unusual warm spell pushes into higher brackets. Traders building automated resolution workflows should note that Wunderground's historical data requires manual temperature-unit verification via the settings gear icon; API integrations pulling this data should account for potential unit mismatches if feeding directly into conditional order logic.

The New Zealand MetService issues 10-day forecasts that become reliable roughly five days ahead; traders monitoring this market programmatically should flag forecasts predicting anomalous warmth or cold snaps. No scheduled events or infrastructure changes affect Wellington's airport station operations on that date. For traders using copy-trading or bot-based approaches, this market's low liquidity and absent crowd activity means manual position-sizing and direct Wunderground verification at settlement remain necessary safeguards against data-source discrepancies.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Review UK, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
