Highest temperature in Wellington on August 9?

Platform comparison

Market context

Polymarket is pricing this contract at **0% YES**, so the market is effectively saying there is no current expectation that Wellington’s 9 August 2026 high will land in the specified temperature band. On Polymarket, that price is expressed in USDC on Polygon through conditional tokens, so the live quote reflects the crowd’s read on the Weather Underground resolution source rather than a forecast model in isolation.

For context, Wellington’s August climate is usually cool and steady, with averages around the low teens Celsius and relatively tight day-to-day variation. Independent weather summaries place typical August highs near **12°C** and lows only a few degrees lower, which makes a materially warmer outcome unusual, while current local forecast pages cluster today’s range around **9–12°C** with occasional rain or drizzle and breezy conditions.[2][13][16] That sort of setup tends to favour a narrow temperature outcome rather than a sharp intraday spike.

A trader watching this market should focus on the airport station’s evolving daytime readings, because the contract settles on the highest value in Weather Underground’s **Daily Observations** table, not the headline high in the summary box. The main catalysts are any change in the synoptic setup over Wellington International Airport—cloud break-up, sun angles after morning rain, or a drying wind shift—rather than scheduled announcements. Weather Underground’s hourly forecast for Wellington currently points to a cloudy, damp morning turning sunnier later, which is exactly the kind of pattern that can nudge the recorded high one band higher if the afternoon clears more quickly than expected.[14][10]

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 Alternative 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.

Is Polymarket legal in the UK?

Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.
