April 5th in Bloomfield sits right at the edge of spring's uncertainty — expect a high near 54° and a low around 35°, but 104 years of history show this date can swing wildly, from a balmy 82° back in 1921 to a brutal 20° in 1982. There's about a 1-in-3 chance of rain, though snow is nearly off the table at just 2%.
Bloomfield earns its New England stripes with a staggering 127-degree spread between its all-time records — from a scorching 103° on July 22, 2011 to a bone-chilling -24° on February 16, 1943. The wettest single day on record dumped 6.1 inches during the infamous 1938 hurricane, and a December storm in 1945 buried the town under 17.7 inches of snow.
Bloomfield peaks in the heat of mid-to-late July, when average highs reach 85°, then bottoms out in mid-January with highs barely scraping 35°. If you're dodging rain, avoid early April — it's statistically the wettest week of the year, averaging just over an inch of precipitation. For the best of all worlds, aim for September, when highs hover around 75° and the rain backs off.
