Is this year warmer than usual?

A whole year, month by month, against the thirty years before it. The readings come from NOAA’s co-operative station at Canoe Brook in Short Hills, which has recorded a daily maximum and minimum since 1931 — the same station the dashboard measures today against. Move the slider to change the year.

And is the town warmer than it used to be?

One year is weather. Thirty years is climate — long enough that a hard winter or a hot summer averages out. The chart below splits the station’s record into three thirty-year stretches and draws the average of each month in each. The first two lie almost on top of one another; the most recent runs warmer in all twelve months of the year.
