Northwesterly (?) gale affects east coast of England. įog daily 17th - 21st December (London/South). Lamb (CHMW) ascribes this reversal to a renewal of volcanic activity. The decade from 1810-1819 was the coldest in England since the 1690's. There was a great deal of ice on the Thames during most of these winters, but the ice does not seem to have been strong/thick enough for people to walk from one side to the other.ġ809-1819: After a relatively benign period from 1790 (several warm summers & less cold winters), these years saw a return to often harsh winters & unsettled, cold & wet summers. 10 wet summers noted: just 3 'dry' years in this period noted: 1802, 1807 & 1840. However, as always with such sweeping statements, there were notable exceptions! The following years and / or seasons are noted as being 'dry' during these first 40 years of the 19th century: For example, from the Greenwich series (LW), the wettest years in these four decades did NOT coincide with the EWP set for London, it appears that 1821 (~140%) and 1824 (~150%) captured the most rainfall, and two years (1817 & 1819), although not 'notable' in the England/Wales-wide series, were wet in the London/SE area. There is evidence from London-area data that (as might be expected) there were notable regional variations. In particular, 1828 & 1839 (~120%) stand out, though even these don't appear in the 'top-10' of wettest years in that series. Using the EWP series, the following years had precipitation %ages of roughly=/> 110%. These first 40 years of the 19th century often contained references to excessive rainfall, floods etc. (T: warm/cold events R: dry/wet events S: 'stormy' events) Date
