The Lake District is in fact England’s wettest region. Precipitation varies within
its boundaries—Penrith, located in the Eden Valley, receives just 30-35 inches annually,
whereas Seathwaite in Borrowdale receives an average of 130-40—but the region overall
averages more than 80 inches. England as a whole averages around 33 inches per year,
so Wordsworth’s statement is essentially accurate.
