April 5th in Baldwin runs mild, with highs averaging 57° and lows around 37° across 38 years of records. The date has a wild range, though — temps have swung from a bitter 22° in 2016 all the way to a shirt-sleeve 86° as recently as 2023. Rain is a coin-flip-ish 37%, but snow is essentially off the table.
Baldwin's weather has real teeth at the extremes: the all-time record high of 102° and record low of -16° both landed in 1936, just six months apart. The wettest single day on record dumped 6 inches of rain in September 2004, and an early-season snowstorm in November 1950 buried the area under 12 inches in one shot.
Summer is the sweet spot — highs peak around 84° the week of July 9–15 and stay comfortable through August. If you're cold-averse, avoid mid-January, when average highs bottom out at just 35°. June is the wettest stretch of the year, averaging over an inch of precipitation per week, so pack accordingly.
