If you’ve lived around Norfolk County for more than a week, you know the drill. You check the forecast for weather in Medfield MA on a Tuesday, see sun, and by Thursday you’re digging your SUV out of a snowdrift that wasn't supposed to be there. It’s New England.
Weather here isn't just a topic of conversation; it’s a lifestyle. Honestly, it's a bit of a chaotic one.
Right now, as we sit in mid-January 2026, the town is basically a giant ice cube. We just came off a Saturday that saw a high of 38°F with a messy mix of rain and snow. Today, Sunday, January 18, the sky is dropping actual snow with a 65% chance of showers tonight. The high is struggling to hit 34°F. It’s the kind of damp cold that gets into your bones and stays there until May.
The Medfield Microclimate: Why Your App is Often Wrong
Medfield has this weird habit of being just a few degrees colder than Boston but slightly less buried than Worcester. We sit in a geographic "sweet spot" (if you want to call it that) where the Atlantic Ocean’s moderating influence starts to fail.
While the city might get a "wintry mix" that turns to slush by noon, Medfield often holds onto the freezing line. This leads to that lovely phenomenon we saw just last week: long-duration ice events. On January 6-7, 2026, the town got smacked with multiple rounds of freezing rain. It wasn't the "pretty" kind of snow you see on postcards. It was the "my-driveway-is-now-a-hockey-rink" kind of ice.

According to data from the Medfield Rhododendron Reservation station, January is historically our windiest month. We’re talking average gusts around 20 mph, though recently we’ve seen higher. When you combine 28°F temperatures with a 5 mph southwest wind—like we have tonight—the "feels like" temp drops down to a biting 22°F.
- Current High: 34°F (Jan 18)
- Current Low: 28°F (Jan 18)
- Next 48 Hours: Sunny but colder, dropping to 19°F tomorrow night.
Basically, if you’re planning on a morning walk at Rocky Woods tomorrow, wear the heavy wool. The sun might be out, but the temperature isn't going to break freezing.
Seasonal Shifts and the "New Normal"
New Englanders love to complain that "the seasons are changing," and the data actually backs them up. A 2022 Massachusetts State Climate Summary noted that temperatures in the state have risen nearly 3.5°F since the early 20th century.
What does that mean for Medfield? It means our winters are becoming more erratic. Instead of a steady three months of snow, we get these "see-saw" cycles. One day it’s 51°F (like it was earlier this month on January 14), and three days later it’s 20°F.

This creates a massive headache for local DPW crews. When the ground thaws and then flash-freezes, the potholes on Route 109 start multiplying like rabbits. The town has seen an increase in "extreme precipitation events"—a fancy term for when it rains or snows so hard the drainage systems just give up.
The Best and Worst Times to Be Here
If you’re moving here or visiting, let's be real about the calendar.
The "Avoid It" Months: March is the consensus winner for the worst month. It’s "Mud Season." The snow is grey and melting, the trees are bare, and it’s too cold for a light jacket but too "spring-adjacent" for a heavy parka. August is a close second because of the humidity. The dew point in Medfield can hit 65°F in mid-summer, making a simple trip to Brothers Marketplace feel like a marathon in a sauna.
The "Glory" Months: September and June. Hands down. In September, the average high is around 73°F. The humidity finally breaks, and the air gets that crisp "apple picking" feel. June is when the rhododendrons at the reservation actually bloom, and the daytime highs of 77°F are perfect. You get about 208 hours of sunshine in those months. Compare that to the 53% overcast rate we have right now in January.

Managing the Medfield Winter Blues
Since we’re currently looking at a forecast that stays below freezing for the next several days—including a brutal drop to 6°F by next Monday—you need a survival plan.
- Check the Wind, Not Just the Temp: A 25°F day with no wind is beautiful. A 30°F day with 15 mph gusts from the northwest will kill your mood in five minutes.
- Humidity Matters in Winter: Our current humidity is 93%. High humidity in winter makes the cold feel "wet" and more piercing. Invest in a high-quality base layer (merino wool is the gold standard).
- The 48-Hour Rule: Don't trust a Medfield forecast more than 48 hours out. The jet stream often sits right over us, meaning a storm tracking 50 miles east or west is the difference between six inches of powder and a rainy Tuesday.
Looking ahead at the next week, Tuesday (Jan 20) is going to be the coldest day of the stretch. We’re looking at a high of only 23°F and a low of 9°F. If you have outdoor pipes that aren't well-insulated, that's the night to leave the faucets dripping.
The weather in Medfield MA is a test of character. It’s fickle, it’s often grey, but it makes those rare, perfect 70-degree October days feel like a reward we actually earned.
Actionable Next Steps: Check your car's tire pressure tonight; these 20-degree temperature swings usually trigger the "low pressure" sensor. Also, clear your storm drains of any ice or debris before Wednesday's predicted "rain and snow" mix to prevent your driveway from flooding when the temperatures briefly hover near the freezing mark.
