Highest temperature in Wellington on August 11?

Platform comparison

Market context

Wellington’s airport temperature market is priced as a near-certain *underdog* for anything much above the low teens, with the crowd currently putting **0%** on the headline YES side. That is consistent with the broader August picture: Wellington’s winter climatology typically centres on cool, changeable conditions, and current forecasts point to a cloudy day with a modest maximum around 12°C. Accuweather’s Wellington forecast shows 55°F/46°F with cloud cover and only a 2% precipitation chance, while the World Weather Information Service gives a daily range of 8°C to 12°C for 11 August[3][1]. On that basis, the market consensus sits around the **12°C–13°C** band, making those ranges the obvious favourites and leaving the higher brackets as long-shot contrarian shots[6].

For handicappers, the key historical read is that Wellington’s August highs are usually tightly clustered rather than explosive; WeatherSpark and other climate guides put average August highs around 12°C, with wind and cloud often limiting upside[12][13][17]. That makes the current zero-price on YES less a signal of special certainty than a reflection that traders see the weather profile as capped. The value question is whether a brief midday lift, a drier break, or a better-than-expected local reading can push the airport station above the consensus band; the main risk to the favourite is not a heat surge, but a forecast miss either side of 12°C that leaves the top reading lower than expected[1][6].

The catalysts to watch are the next MetService-style forecast updates, hourly station observations, and any revision to the Weather Underground Daily Observations table, because that table—not the summary high/low—determines settlement here[16]. The market also notes that revisions inside the settlement window can count until the first datapoint for the following date is published, so late-night updates may matter more than the daytime forecast narrative[6]. Given the present setup, the consensus appears anchored to a narrow 12°C outcome, while any value on the board is likely to come from contrarian positions in cooler bands if cloud, southerlies, or a weak daytime recovery hold the airport below the expected peak[1][6].
