Fair Value Reasoning:

The primary meteorological authority, MetService, explicitly forecasts a high of 18°C for Wellington on March 20, accompanied by 'Southeasterlies'. In Wellington, southeasterly winds are a strong cooling vector from the ocean (Antarctic direction), which typically acts as a hard cap on temperatures, making it difficult to exceed the forecast. AccuWeather predicts 65°F (18.3°C), and MeteoProg predicts 17°C. Given the cooling wind and potential cloud cover increasing in the afternoon ('showers from afternoon'), the risk is skewed towards the downside (17°C) rather than the upside (19°C+). Thus, fair value is heavily concentrated on 18°C (baseline) and 17°C (downside risk), while the probability of 19°C and above is significantly overpriced due to the cold wind dynamic.

Movers

March 16, 2026 - March 18, 2026, the price of 19°C dropped significantly from 29.5c to 14.5c, as weather models increased confidence in the 'southeasterly cold wind' scenario, eliminating the possibility of higher temperatures. March 18, 2026 - March 18, 2026, the price of 16°C fell rapidly from 19.5c to 9c, as although the forecast is cool, the consensus range of 17°C-18°C solidified, reducing the likelihood of an extreme low. March 16, 2026 - March 18, 2026, the price of 17°C rose from 23.5c to touch 35c before settling around 30c, as market capital hedged the downside risk of the temperature missing the 18°C target.
