Climatic comparisions

If there's one thing American's agree on, it's that both London and Portland are very wet indeed. But what are the facts? London and Portland both average 153 “wet days” per year, defined as a day with greater than 1/4mm rainfall. This is despite the fact that Portland has twice as much actual rain (100cm vs 60cm). And despite that fact, it is also consistently sunnier. Temperature wise, Portland is also slightly warmer than London throughout the year. Want diagrams? You've got them...











The graphs also indicate Portland's climate to be more seasonal then London's, with comparatively few wet days in the summer months...
