Market context
Wellington’s **highest temperature on 3 August** will be set by the Wellington Intl Airport Station reading, so the key question is whether the day produces a brief midday warm-up or stays close to the cool winter norm. Recent forecast material for Wellington points to a very tight temperature band: one August outlook shows 3 August around **19°C/8°C** with sunshine, while another Wellington forecast has daytime highs near **9°C** and lows around **8°C**; current observations also sit in the single digits to low teens, with BBC and MetService both showing roughly **10°C** or below at the station and broadly cool, breezy conditions[2][4][9][10].
That matters because a **0% YES** price implies the market is already treating the upper temperature bands as extremely unlikely, and Wellington’s winter climatology supports that caution. August average highs in Wellington are commonly described as roughly **12°C** or lower, with frequent rain days and brisk winds, so a climb into substantially warmer ranges would need an unusual, localised swing rather than ordinary seasonal variability[5][7]. Even the more optimistic forecast snippets still cluster around the high teens at most, which is notable for a city that is usually stable and cool in August[2][5].
Traders should watch the station-specific midday and afternoon updates rather than the city forecast alone, because the settlement depends on the **daily high recorded at Wellington Intl Airport** and small timing shifts can matter if a short-lived warm pocket appears before cloud, showers or strengthening southerlies arrive[15]. The most relevant catalysts are forecast revisions from MetService and BBC-style station observations, plus any change in wind direction or cloud cover that could suppress or briefly lift the peak temperature[4][10][12].

FAQ
- When do sports markets resolve?
- Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.
- Can I bet on individual matches?
- Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.
- What are live sports odds on Polymarket?
- Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.
- Which sports markets are available?
- Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.
- What's the difference between match odds and outright odds?
- Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
