Will London reach a temperature of 20°C on Monday, October 12, 2026?

No

<think> Okay, let's tackle this. The market question is whether London will reach 20°C on October 12, 2026, with the market closing at 23:00Z that day. Resolver 1 looked at Open-Meteo's data for St James's Park and Heathrow. Both stations showed a peak of 17.4°C during the window. They concluded "No" (option 1). Resolver 2 checked multiple sources: Heathrow and City Airport METARs peaked at 18°C, Wunderground had 16°C, and St James Park reported 18.7°C. All below 20°C, so they also pick "No". Both resolvers agree on the answer. They used different but credible sources, all of which are official or widely recognized stations in London. The highest temps reported are consistently under 20°C. There's no conflicting data here. Since the resolution criteria require a max of 20°C or above from the official stations, and all evidence shows max around 17-18°C, the "No" outcome is correct. No need to question the evidence because all sources align. The answer should be 1. </think> ANSWER: No

Resolution criteria: - "Yes": Wins if a maximum air temperature of 20°C or above is recorded in London strictly after 2026-10-11T23:00:00Z and at or before 2026-10-12T23:00:00Z. - "No": Wins if the maximum air temperature recorded in London during the same window remains below 20°C. Clarifications: - "Maximum air temperature in London" refers to the highest temperature reading observed at a recognised official or widely used meteorological station serving central London (such as Heathrow, St James's Park, or London City Airport) during the specified window.
