Graphs of Annual Blue Hill Observatory Climate Data
Weather observations on Blue Hill began on February 1, 1885, but the annual mean temperature plot below includes data for 1831 to 1884 from nearby locations that have been carefully adjusted to the Great Blue Hill summit, to extend the Observatory mean temperature record back to 1831.

I love the graphs on first blueberries!
Where did you get that data?
thanks
Our data for the date of the first ripe blueberries has been observed right on the summit of Great Blue Hill near the Observatory every year since 1886.
