When Does Snow Start in Concord, NH? Book Plowing Before the First Storm

If you manage a parking lot, office, retail plaza, HOA or other commercial property in Concord, the question isn't whether winter will show up. It's how early the first snow arrives—and whether your plow contractor is already booked when it does.

NOAA daily records from Concord Municipal Airport put the median first measurable snow (0.1 inch or more) at around November 20 for the 1991–2020 climate-normals period. The median date for the first day with an inch or more is around December 1–2. Those are midpoints, not guarantees: about one year in ten sees measurable snow by early November. The earliest measurable snow in the long Concord record came on October 10, 1979 (1.0 inch).

As of mid-October 2026, Concord still has no measurable snow for this season. That quiet stretch is when commercial properties should finish fall cleanup and lock in commercial snow removal before the first real storm.

What the Climate Record Says About First Snow in Concord

Concord Municipal Airport is the official climate station for the capital area. The National Weather Service's 1991–2020 seasonal normals show about 67.7 inches of snow in a typical year, with roughly 30 days of measurable snow and about 16–17 days with an inch or more.

Monthly normals put about 0.8 inches in October and 2.5 in November, then the bulk of the season (14.3 Dec, 17.1 Jan, 16.9 Feb, 13.6 Mar, 2.5 Apr).

October and November are light on average, but that is when first events show up and unprepared lots get caught. The older NWS Concord climate narrative still holds: the first inch-or-more snowfall is likely between mid-November and mid-December, with lasting snow cover usually mid-December into late March.

Treat early to mid-November as the deadline to have a plow and ice plan in writing—not the day the forecast mentions the first storm.

Why Commercial Properties Should Book Before the First Storm

When the first advisory hits, every property manager in the Concord area is making the same calls. Contractors who still have open routes fill them fast. Waiting until the radar lights up usually means no guaranteed response time (seasonal contracts get priority), harder ice control once snow packs, messy snow piles that drain and refreeze across the lot, and gaps overnight or on weekends when many commercial properties still need to open.

Globe Green's commercial snow removal covers plowing, salting and sidewalk clearing for businesses and commercial properties in Concord and nearby towns. We do not plow residential driveways—our winter routes are built for commercial lots, access drives and walkways that have to open on time.

If fall cleanup is still open, finish it in the same window. Leaves under early snow make ice worse and clog drains; our fall cleanup guide for Concord covers what to finish before mid-November, and landscaping services can handle the leaf and bed work.

What to Line Up Before the First Measurable Snow

Use the quiet weeks of October and early November for site prep, not just paperwork.

1. Walk the lot with a winter eye. Note where water ponds, where shade keeps ice longest, and where trucks and plow wings need clearance. Mark curb lines, hydrants, cleanouts and island edges while you can still drive stakes into the ground.

2. Choose snow storage before the plow arrives. Pick a sunny, out-of-the-way pile that does not drain meltwater back across the lot or into walkways. NHDES winter BMPs stress planning storage so melt does not refreeze across cleared pavement.

3. Decide your ice standard. Bare pavement at opening, or a packed treated surface overnight? Put trigger depths, response windows and salt/sand expectations in the contract so nobody is guessing at 4 a.m.

4. Ask about salt reduction and liability. New Hampshire has more than 50 waterbodies impaired for chloride. NHDES's Green SnowPro program trains commercial applicators in calibrated, lower-salt practices that still prioritize safety. Under RSA 508:22, property owners or managers who hire Green SnowPro–certified applicators can receive liability protection related to snow and ice conditions when program requirements are met. Ask whether your contractor is certified and how they calibrate spreaders.

5. Protect hardscapes from winter abuse. Salt and freeze-thaw are hard on pavers and wall joints. If you have a patio, walkway or retaining wall next to the lot, note low spots and loose units now for spring, and keep plow blades off decorative edges.

6. Clear the last organic debris. Heavy leaf mats under early snow feed ice and spring snow mold on turf strips. Finish leaf removal and edge marking before the median first-snow window.

A Simple Concord Timeline

• Now through early November: Finish fall cleanup, stake edges, designate snow piles, sign the seasonal plow contract.
• Around November 20 (median first measurable snow): Expect the first real events in a typical year; your contractor should already know your triggers and access.
• Late November through early December: First inch-or-more storms become likely; confirm ice product and overnight contacts.
• December–March: Peak season (most of Concord's ~68 inches). Stick to the written plan.

Watch the forecast, not only the calendar. Early Novembers happen, and so do quiet Decembers that end in one big storm. The climate medians tell you when to be ready; they do not replace a seasonal contract.
