April 5 in New Haven sits right in the thick of spring's unpredictability — the average high is 55° but the date has seen everything from 83° (1988) to a brutal 16° low (1995). There's nearly a coin-flip chance of rain today historically, and snow is still on the table about one year in nine.
New Haven's weather has real teeth on both ends — the thermometer has swung from a scorching 106° in June 1988 all the way down to -22° in January 1985, a range of 128 degrees. A single day in June 1989 dumped 4.4 inches of rain, and a March 1964 snowstorm buried the area under 12.6 inches.
Summer is the main event here, with mid-July averaging highs of 85° and also delivering the wettest stretch of the year at over an inch of precip per week. Winters are genuinely cold — January highs barely crack freezing at 31° — so plan outdoor trips between May and September for the most reliable weather.
