Starting in 1996, Alexa Internet has been donating their crawl data to the Internet Archive. Flowing in every day, these data are added to the Wayback Machine after an embargo period.
Annual and monthly averages for a range of elements can
be selected by clicking a station location on the map to
the left or by selecting from the menu below.
All values except rainfall are given to a precision of
one decimal place. For 'Days of' elements, 0.1 equates to
one day every ten years, 0.5 to one day every two years,
2.5 to five days every two years, and so on.
