As April unfolds in New Canaan, anticipate a medley of springtime weather. The upcoming week promises a blend of mild temperatures, occasional showers, and moments of sunshine. While no significant storms are expected, it’s wise to stay prepared for the varied conditions that early April often brings. 

Friday, April 11 will be chilly and wet with cloudy skies and a high around 48°F. Occasional light rain and drizzle are expected during the day, becoming steadier and heavier in the evening and overnight. Winds will be easterly around 10–15 mph, with gusts up to ~25 mph, and the damp air will keep humidity near saturation. The chance of precipitation is about 80%, with up to 0.5–0.8 inches of rainfall possible by late Friday night. While no weather advisories are in effect, local drivers should take care during commutes as heavier rain could reduce visibility and create slick conditions.

Saturday, April 12 stays cool and rainy with highs around 47°F and a nighttime low near 39–40°F. Skies will remain overcast with rain likely for much of the day with up to 90% chance of precipitation, tapering to lighter showers or drizzle by the evening. Northeasterly winds of 10–15 mph will make it breezy, and the atmosphere will be very humid during periods of rain. Another quarter to half an inch of rain could fall on Saturday, so soggy conditions are expected throughout the day. Watch for minor ponding on roads and walkways.

Sunday, April 13 is expected to start with some lingering moisture but then improve, with a high  of 55°F and a low around 40°F. Areas of morning mist or drizzle are possible early on, but skies should turn partly sunny by afternoon as drier air moves in. The chance of any rain is fairly low, and northwest breezes up to 10 mph will usher in less humid air. Sunday afternoon should offer the best window of the weekend for enjoying time outdoors.

Monday, April 14 will feel much warmer and brighter, with mostly sunny skies and afternoon highs reaching the low to mid-60s. The morning starts cool, around 50°F, but sunshine and a light west wind will help temperatures climb steadily through the day. Humidity will be moderate, making for comfortable conditions, and no rain is expected. The UV index will be higher, peaking around 7 in the afternoon, so consider sun protection despite the pleasant weather. 

By Tuesday, April 15th spring warmth will peak with highs in the upper 60s to near 70°F and nighttime lows in the low 40s. Skies should be mostly sunny and the day will be quite pleasant; expect a light to moderate west-southwest breeze around 10 mph. Humidity remains comfortable, and the chance of any precipitation is very low. It will be a gorgeous, breezy day with a high UV index near 7 and no weather hazards to worry about. Local parks and trails will be especially inviting under these near-ideal conditions.

Wednesday, April 16 turns cooler again with an afternoon high in the mid-50s and overnight lows dipping into the mid-30s. Expect a mix of sun and clouds – forecasts range from partly sunny to mostly cloudy – but it should stay dry with virtually no chance of rain. West-northwest winds around 10 mph will bring in crisp air, keeping humidity levels modest. No advisories are anticipated; it will just be a notably cooler day following Tuesday’s warmth.

The weather settles into a calm, seasonable pattern by Thursday, April 17, with daytime highs around the mid-50s and nighttime lows near 40°F. After a cloudy start in the morning, sunshine will return, leading to mostly clear skies later in the day. Winds will shift to the northwest at about 10–15 mph, and with the drier air, humidity will be moderate. There is virtually no chance of precipitation, and the UV index will climb back into the High range during the afternoon sunshine.

Embracing the season’s unpredictability adds to the charm of this time of year. Whether you’re chasing sunbeams or dodging raindrops, New Canaan’s springtime mood has a little something for everyone.
