Hartford is starting Tuesday with clear skies and a crisp upper-40s chill, but the afternoon will be a straightforward fall win: sunshine, light north winds and a high near 57. The bigger story is the rebound ahead, with temperatures climbing into the low 70s by Friday before a mostly pleasant Halloween.

Sunny Tuesday, Colder Night

The National Weather Service expects dry weather across Hartford through the day, with north winds generally 2 to 8 mph and no rain in the forecast. After sunset, skies stay mostly clear and temperatures dip to around 35, so early Wednesday plans may need more than a light layer. No land advisories are posted for Connecticut in the current outlook.

Late-Week Warmup Arrives

Wednesday remains mostly sunny and reaches about 59, followed by a sharper warmup Thursday, when Hartford could hit 68. Friday looks like the warmest day of the stretch, with sunshine and a high near 72; west winds may run 2 to 10 mph, enough to add a little breeze without derailing outdoor plans.

Halloween Looks Mostly Sunny

Saturday should stay mostly sunny with a high near 64, a solid setup for Halloween errands and afternoon events. Clouds increase Saturday night, with a low around 42, while Sunday turns mostly cloudy but remains mild near 65.

The next rain chance waits until after midnight Sunday, when showers have about a 30% chance of developing. Monday brings a 46% chance of showers and a high near 66, so the weekend’s dry stretch likely ends with a damp start to the new week.
