Quick answer: For a typical northbound Appalachian Trail thru-hike starting March–April, carry a 20°F quilt through Georgia, North Carolina, the Smokies and southwest Virginia; many hikers switch to a 40°F quilt from roughly May through the Mid-Atlantic summer; then return to a 20–30°F quilt for New Hampshire and Maine from late August. Cold sleepers and February starters should consider 10–15°F. The AT is humid, so protect down from moisture.

The Appalachian Trail runs about 2,200 miles from Springer Mountain in Georgia to Katahdin in Maine, and the right quilt for the AT depends on when and where you'll be. A March start in the southern Appalachians can bring snow and teen-degree nights; July in Pennsylvania can be too warm for any quilt at all. This guide breaks down typical overnight lows by section and suggests quilt ratings for northbound (NOBO), southbound (SOBO) and section hikers.

Temperature figures below are typical ranges based on regional climate patterns, not guarantees. Weather on the AT varies widely year to year and with elevation — check forecasts (including mountain-point forecasts) before each section, and remember that most quilt ratings aren't standardized. See how quilt temperature ratings work.

Why the AT is tricky for quilts

The AT has three features that shape quilt choice:

  • Long, variable seasons. A NOBO hiker walks from late winter into summer and out into early fall over five to seven months.
  • Humidity. The East is wet. Rain, fog and high dew points mean down quilts gradually take on moisture, especially over several days without sun.
  • Elevation swings. The trail climbs from low gaps to over 6,000 feet in the southern Appalachians and crosses exposed alpine terrain in the White Mountains. Ridges are colder and windier than towns below.

Georgia and North Carolina

Many NOBOs start between early March and mid-April. The first 200 miles can feel deceptively mild during the day, but nights at 3,000–5,000 feet routinely drop below freezing in March, and late-season snow is common enough that it shouldn't surprise you. A 20°F quilt with a sewn or zippered footbox, a good draft collar and a ground pad around R 4 handles most nights. February starters face more frequent hard freezes; a 10–15°F quilt or a 20°F quilt plus a substantial puffy is sensible.

Great Smoky Mountains

The Smokies hold the trail's highest point at Clingmans Dome (about 6,600 ft), and NOBOs often reach them in April. Expect nights in the 20s and 30s, with occasional teens and snow, plus wind on exposed ridges. Park rules govern where thru-hikers may stay overnight, typically at designated shelters, so read the current backcountry regulations before you arrive. Hammockers should be prepared for situations where hanging options are limited.

Virginia

Virginia holds roughly a quarter of the trail. By mid-to-late May most northbounders hit consistently warmer nights, and many swap to a lighter quilt — commonly a 40°F model — around the middle of the state. If you only own one quilt, a 20°F quilt can be used open like a blanket on warm nights; it's a few ounces heavier but avoids a mail drop.

The Mid-Atlantic in summer

From West Virginia through New York in June and July, nights are often warm and muggy. A 40–50°F quilt is plenty, and some hikers carry nothing more than a light quilt or blanket. The bigger concern is moisture: high humidity and frequent storms mean down picks up dampness. Air your quilt in the sun at lunch whenever you can. A summer quilt with a water-resistant shell is ideal here.

New England

Northbounders typically reach the White Mountains in August. Above treeline on the Presidential Range, weather can turn severe quickly — Mount Washington is famous for extreme wind and fast-changing conditions — and nights below freezing are possible even in late summer. Many hikers switch back to a 30°F quilt (or their original 20°F) somewhere in Vermont or New Hampshire. Maine in September brings frosty mornings, and by October nights near or below freezing are common.

Southbound and flip-flop hikers

SOBO hikers usually start at Katahdin between June and July. Early on, Maine is buggy and humid with lows in the 40s–50s; a 30–40°F quilt works. By October and November in Virginia and the southern Appalachians, nights fall into the 20s and colder, so plan to have a 20°F quilt (or 10–15°F for cold sleepers) by roughly southern Virginia. Flip-floppers who start in the middle of the trail in spring and finish north then south often get the mildest overall temperatures and can sometimes manage with a single 20–30°F quilt plus layers.

One quilt or two?

Swapping quilts saves weight in summer but adds logistics: mail drops, timing a bounce box, and the risk of sending your warm quilt home right before a cold snap. A 20°F quilt is often only 6–10 oz heavier than a 40°F quilt from the same maker. Many hikers decide the convenience of carrying one quilt the whole way is worth it, especially with a quilt that has an open-able footbox so it vents like a blanket. See open vs sewn footbox for the venting trade-offs.

If you do swap, don't send the warm quilt home until you're past the last real cold risk. Late spring frosts in the southern and central Appalachians catch out hikers every year.

Humidity, down and the AT

Moisture is the AT's quiet quilt-killer. Several damp nights in a row, fog, and storms can reduce down's loft noticeably. Good habits help:

  • Use a waterproof pack liner and keep the quilt in it all day.
  • Dry the quilt in sun at lunch or in town every chance you get.
  • Consider hydrophobic down and a shell with good DWR.
  • Vent the tent or tarp to reduce condensation; see using a quilt in a tent.
  • Wash and restore loft once or twice on a thru-hike; see how to wash a down quilt.

Synthetic quilts shrug off humidity better but are bulkier and heavier for the same warmth. For summer-only sections, a synthetic quilt is a reasonable choice; for the cold ends, down remains the norm. Our down vs synthetic comparison goes deeper.

Hammocks on the AT

The AT is mostly forested, which makes it one of the best long trails for hammock camping. Hangers need both a hammock top quilt and an underquilt rated for the season. Underquilt warmth matters most in spring: a 20°F underquilt is standard for March–April starts. In summer, a 40–50°F underquilt or even a pad is enough. Bring a tarp large enough for long, wind-driven Appalachian storms, and consider a top cover for windy spring nights — see top covers and hammock socks.

Shelters, tents and campsite choice

The AT has a network of three-sided shelters, roughly a day's walk or less apart, plus established tent sites. Shelters block wind and rain, but they're often drafty, crowded in spring and colder than you'd expect because cold air flows through the open front. A tent pitched in a sheltered spot among trees can actually be warmer. Wherever you sleep, avoid low gaps where cold air settles on still nights, and avoid exposed balds in wind. If you use a tent, see using a quilt in a tent for drafts and condensation.

Sleeping pads and sleep clothes

For ground sleepers in shelters or tents, pair a spring quilt with a pad around R 4 or higher; shelter floors are cold wooden platforms, and a pad matters as much as the quilt. In summer, an R 2–3 pad is fine. See sleeping pad R-value for quilts. A light down puffy, a warm hat and dry socks reserved for sleep stretch any quilt by several degrees. The quilt layering system shows how to plan that.

  • Rating: 20°F for spring and fall ends; 40°F optional for summer.
  • Fill: 800–950 fill power down, ideally hydrophobic; see down fill power explained.
  • Weight: A 20°F down quilt typically runs about 18–26 oz depending on fill power and size.
  • Width: Wide if you side sleep or toss and turn; drafts are a common cause of cold nights.
  • Pad attachment: Useful for side sleepers on cold nights; see pad attachment systems.

Frequently asked questions

What temperature quilt do I need for the Appalachian Trail?

Most northbound thru-hikers starting in March or April carry a 20°F quilt, swap to a 40°F quilt or lighter setup for summer in the Mid-Atlantic, and return to a 20–30°F quilt for New England in late summer and fall. Cold sleepers and February starters often go to 10–15°F.

Is a quilt warm enough for the Smokies in spring?

A true 20°F quilt with a draft collar, an insulated pad (R 3.5 or higher on the ground) and warm sleep clothes handles typical spring nights in the Smokies. Cold snaps into the teens happen, so be ready to wear your puffy and hat to bed.

Down or synthetic for the AT?

Down is still the most common choice because of its weight-to-warmth ratio. The AT is humid, so a water-resistant shell, hydrophobic down, a waterproof pack liner and airing the quilt on sunny breaks matter more than on drier trails.

Can I hammock the whole Appalachian Trail?

Largely, yes — the AT is mostly forested and many thru-hikers hang. A few exposed or regulated areas (balds, some above-treeline zones, and site-specific rules) need planning, so check current regulations before each section.
