As the week moves on, the state will shift from summer-like temperatures in the 70s to a more fall-like feel by midweek. That’s thanks to an incoming cooler air mass and high pressure blocking additional tropical influences.

Here’s a closer look at what folks from Stamford to Torrington can expect.

Sunday: Damp Morning, Bright Afternoon

Places like Bridgeport and New Haven wake to clouds and light showers along the shoreline. Inland spots such as Waterbury and Litchfield also start the day under a blanket of moisture.

The tropical air makes things feel sticky, with humidity running high.

Temperatures Across the State

By midday, skies clear across much of Connecticut. Highs will range between 71 and 76 degrees along the coast, and between the low to upper 70s in northern and inland towns like Danbury and Torrington.

This warm-up, paired with muggy humidity, makes it feel more like late summer than early fall.

Monday: More Comfortable Air

As tropical moisture pulls away, humidity eases up a bit. Cities such as Hartford and Norwalk can expect a more pleasant feel, even as temperatures stay in the mid to upper 70s.

Sunshine dominates most of the day. It’s a great setup for outdoor activities.

Ideal Conditions for Shoreline and Inland Towns

Whether you’re strolling the beach in Milford or hiking trails in the Litchfield Hills, Monday’s weather looks perfect for getting outside. Winds stay light, and skies remain mostly clear.

Tuesday: Holding on to Warmth

The warm streak keeps going Tuesday, with highs again in the 70s statewide. Residents of New Britain and Middletown get one last taste of balmy air before temperatures dip midweek.

Great Day for Autumn Events

Pleasant sunshine and moderate humidity make Tuesday ideal for seasonal events and early fall markets across Connecticut. Think pumpkin patches in East Hartford or art fairs in Fairfield.

Midweek Shift: Cooler, Fall-like Weather

By Wednesday, a cool air mass settles into the region, bringing highs down into the 60s. For folks in Stamford and Norwich, it’ll feel like a real change from the mild start to the week.

High Pressure Means Stability

High pressure builds over the Northeast, blocking any future pushes of tropical moisture. Expect a more stable, dry pattern for late week—just what fans of crisp fall weather have been waiting for.

Breaking Down the Week’s Forecast

Here’s a quick summary for planning:

Sunday: Cloudy, damp morning; clearing afternoon; highs 71–76 degrees along shore, 70s inland.
Monday: Sunshine, lighter humidity; highs mid to upper 70s.
Tuesday: Continued warmth in the 70s; pleasant conditions.
Wednesday: Highs in the 60s; cooler, fall-like feel.
Thursday–Friday: Dry, stable weather under high pressure.

Fall is Around the Corner

Early in the week teases residents with summer-like warmth. The midweek cool-off reminds us that autumn is quickly taking over Connecticut.

Foliage season is just starting to show hints in areas like Guilford and Woodbury. Those crisp, sunny days are perfect for leaf-peeping adventures—if you’re into that sort of thing.

Stay Weather Aware

Tropical moisture is in the mix for Connecticut’s short-term forecast, but there aren’t any tropical storm or hurricane threats coming this week. Still, it’s smart to check local forecasts—especially if you’re near the shoreline.

Morning showers could make Sunday travel a bit slick for those towns by the water. Not the best day for a drive if you can help it.

This week’s weather is split down the middle. Early on, we’ll get a heavy dose of humidity, then things cool off and dry out midweek.

Connecticut’s got something for everyone right now. If you’re hitting the beach in Old Saybrook or hiking around Canton, you’ll find your weather—whether you’re chasing summer warmth or hoping for that first real taste of autumn.
