With only a few days left until the United Kingdom’s fraught departure from the European Union, a different kind of extreme pressure has suddenly hit London. According to UK climatology expert Stephen Burt (Department of Meteorology, University of Reading), the mean sea level barometric pressure at Heathrow Airport reached 1049.6 mb (30.99”) at midnight GMT Sunday night (7 p.m. EST).
Not only is this a record for Heathrow, beating 1047.3 mb from February 7, 1964, but it’s also the highest barometric pressure recorded in London in more than 300 years of record keeping, Burt said in a summary. The previous London record was 1049.1 mb at Kew Gardens at 11 a.m. GMT on January 18, 1882, as reported by Burt in a 2007 article for the journal Weather, “The Highest of the Highs… Extremes of barometric pressure in the British Isles, Part 2 – the most intense anticyclones.” Burt also cited a 2011 paper in the International Journal of Climatology that analyzed near-continuous daily data for the London area from 1692 to 2007.
