Fair Value Reasoning:

According to the latest Met Office forecast updated on March 18, the maximum temperature for London (City of London station) on Saturday, March 21, is expected to reach 15°C. Google Weather (The Weather Channel) forecasts 14°C (57°F), while TimeAndDate predicts 13°C. Weather models indicate a cooling trend/cold front approaching from Friday to Saturday, but Saturday is expected to be sunny, aiding daytime heating. As the local authority, the Met Office's 15°C forecast carries the most weight, followed by Google's 14°C. The market's current favorite of 13°C (23c) appears slightly bearish, undervaluing both 14°C (19.5c) and 15°C (20.5c). Fair value is concentrated in the 14°C-15°C range.

Movers

March 17-18, 2026, the price of the '14°C' option plummeted from 35c to 15.5c before rebounding to 19.5c, driven by updated meteorological models regarding the timing of the weekend cold front, causing the market to oscillate violently between 13°C (faster front) and 15°C (slower front). March 17-18, 2026, the price of the '13°C' option dropped from 32.5c to 19c, then rebounded on the morning of March 18, reflecting extreme market uncertainty regarding the magnitude of the temperature drop.

Divergence

Significant divergence exists. The Met Office (official authority) explicitly forecasts a high of 15°C for Saturday, and Google/Weather.com forecasts 14°C. However, the prediction market's highest-priced option is currently 13°C (23c), while the options matching mainstream forecasts (14°C and 15°C) are trading lower (around 20c). This implies the market is betting on a colder scenario than official forecasts, presenting a positive expected value opportunity to buy 14°C and 15°C.
