Recent numerical weather prediction models from MetService and international centers indicate a daily maximum of 14°C as the most probable outcome for Wellington on August 12, consistent with near-average winter conditions under a mild northerly flow and limited cloud cover. Typical August highs average 12°C, with recent days recording 12–14°C amid variable frontal activity; current guidance shows modest warming potential from reduced southerly influences and light winds, though showers could cap peaks near 13–15°C. Traders assign the highest implied probability to 14°C because ensemble consensus clusters tightly around this value, with lower odds for 15°C reflecting only modest upside from clearer conditions and negligible risk of extremes given the seasonal baseline and short-range forecast stability.
