Many people track when the winter solstice is (“the days only get longer from here!”) but you may not know what your local *teletherm* is (“the days only get warmer from here!”). For us here in Boston the winter teletherm is around January 23rd. Where I used to live in Vermont it was right around Groundhog Day. It’s certainly a time for celebration! ☀️ You can find your city’s teletherm here if you know the nearest weather station: http://teletherm.org/index.html?window=25&var=summer_day&year=1960&cityID=190736 #BostonMA #dataviz #weather #wx #winter
