Highest temperature in Wellington on July 16?

Platform comparison

Market context

Wellington is currently experiencing a brisk south-southwesterly flow with temperatures hovering around 15°C, a condition that has kept the market’s implied probability for any significant heat spike at 0% for the day’s high. This immediate reality aligns with the seasonal norm for mid-July at Wellington International Airport, where daily highs typically cluster near 12–14°C (54°F), rarely exceeding 14.4°C (58°F) even in warmer spells [3]. Historical data confirms that temperatures above 16°C in July are exceptionally uncommon, making the current 0% pricing for higher ranges a rational reflection of climatic constraints rather than a market anomaly [3].

Traders should monitor the evolving pressure system and wind direction shifts over the next 24 hours, as a sustained southerly flow will continue to suppress warming potential. The MetService reports fresh north winds gusting to 43km/h with pressure at 1032hPa, indicating stable but cool conditions that limit thermal excursions [4]. While AccuWeather forecasts a high of 61°F (16.1°C) for today, this remains within the upper edge of historical July variability and does not suggest a breakout event [7]. No major weather announcements or ENSO-driven anomalies are expected to alter this trajectory before the settlement cutoff at 12:00 UTC on 16 July 2026 [8].
