Highest temperature in Wellington on July 6?

Platform comparison

Market context

On 6 July 2026, the Wellington International Airport will record its daily maximum temperature in degrees Celsius, with the market resolving to the specific range containing that peak. The current crowd-implied probability of a "YES" outcome is 0%, suggesting traders believe the temperature will fall outside the defined range, though this contrasts sharply with other platforms. For instance, Lines.com estimates a 51% chance the maximum lands exactly at 13°C, while Polymarket’s adjacent July 5 market shows an 85% probability for 14°C, highlighting divergent implied probabilities versus decimal odds structures across exchanges like Kalshi, Betfair, and Smarkets.

Historically, July is Wellington’s coldest month, with average highs near 12°C (54°F) and lows around 4°C (47°F), making extreme heat unlikely but not impossible [5]. Recent data from NIWA confirms this summer was unusually cool, with the airport reaching 25°C only once compared to the typical five days [7]. This baseline frames the current 0% probability as potentially overconfident, especially given the volatility seen in neighbouring markets where temperatures consistently hover between 13°C and 14°C.

Traders should monitor the MetService’s hourly forecasts and wind patterns, as the current south-south-westerly flow at 44km/h with occasional rain may suppress temperatures further [10]. The settlement window ends at 12:00 UTC on 6 July, so real-time updates from Wunderground and the National Weather Service are critical dependencies [3][4]. Any sudden shift in pressure systems, currently rising at 996mb, could alter the maximum temperature, making the 13°C target a plausible coin flip rather than a certainty [3].

Which platform has the deepest liquidity?

Polymarket — by a wide margin. Top markets reach $50-500M volume, Kalshi ~$200M cumulative, Betfair similar. Deeper liquidity means your trade moves the quote less.

Are all these platforms regulated?

No. Kalshi is CFTC-regulated (US). Betfair and Smarkets are UK Gambling Commission licensed. Polymarket operates without explicit regulation — a different risk profile than a regulated sportsbook.
