Yes

<think> Okay, let's tackle this. The market question is whether London Heathrow had a daily max temperature above 35°C between August 9 and 20, 2026. Both resolvers say "Yes", so I need to check their evidence. Resolver 1 mentions a heatwave on August 13. They reference Met Office news reports stating Heathrow reached 36.5°C that day. The key points are that it's strictly above 35°C and within the specified date range. They also dismissed a 40.2°C claim as a recycled 2022 error but note 36.5°C is sufficient. Resolver 2 points to Tutiempo's METAR archive for EGLL on August 13, 2026, showing 36°C at multiple times. They also cite Weather Underground's 97°F (≈36.1°C) for the day's high. Both sources are reliable, and the temperatures clearly exceed 35°C. The resolution criteria require the daily max from the UK Met Office. Both resolvers use sources that reference Heathrow (EGLL). While Resolver 1 directly cites Met Office reports, Resolver 2 uses METAR records from Tutiempo and Weather Underground. METAR data is official aviation reports, so that's credible. The 36°C reading on August 13 is in the window and meets the threshold. Both resolvers agree the answer is "Yes" based on different but credible sources. Since the temperatures are strictly above 35°C (36°C and 36.1°C), and the date is within 9-20 Aug 2026, there's no conflicting evidence. The NOAA data Resolver 1 mentions isn't current, but real-time reports from Met Office and METAR archives are current. No evidence of a mistake in the resolvers' reasoning. Both answers are valid. Thus, the correct resolution is "Yes" (option 0). </think> ANSWER: Yes

Resolution criteria: - "Yes": Wins if the official daily maximum air temperature recorded at London Heathrow Airport (WMO station 03772 / ICAO EGLL) by the UK Met Office exceeds 35.0°C (strictly greater than) on at least one calendar day from 9 August 2026 to 20 August 2026, inclusive, where each day is defined in UTC. - "No": Wins if the official daily maximum air temperature recorded at London Heathrow Airport (WMO station 03772 / ICAO EGLL) by the UK Met Office does not exceed 35.0°C on any calendar day from 9 August 2026 to 20 August 2026, inclusive, where each day is defined in UTC. Clarifications: - The threshold is strict: a reading of exactly 35.0°C does not satisfy the "Yes" condition; the recorded maximum must be above 35.0°C. - "Daily maximum air temperature" refers to the highest instantaneous or hourly screen-level (1.25 m) dry-bulb air temperature recorded at the Heathrow station within a UTC calendar day, as published in the Met Office's official observation records for that station.
