Shoulder-Season Camping: What Changes in Spring and Autumn

Spring and autumn are, for a lot of people, the best camping of the year. Campgrounds are half empty, the bugs are gone, the light is better, and you can actually book the site you want. The catch is a temperature swing that catches out people whose kit is perfectly adequate in July.

What actually changes

• The overnight low, not the daytime high. A 70°F afternoon can become a 35°F night. Pack for the low.
• Less daylight. Sunset moves an hour or more earlier than midsummer, which compresses your setup window and your evening.
• More condensation. Bigger day-to-night temperature swings mean more moisture on the inside of the fly by morning.
• Wetter ground. Spring especially — cold, damp ground pulls heat far faster than dry summer ground.
• Changeable weather. Forecasts are less reliable in shoulder season. Pack for one step worse than predicted.

The pad is the upgrade, not the bag

This is the single most useful thing to know about cold-weather camping, and most people get it backwards.

The ground conducts heat away from you far faster than air does, and the insulation underneath you is crushed flat by your body weight. So a warmer sleeping bag on a summer pad will still be cold. A summer bag on a well-insulated pad often will not be.

Pad insulation is measured in R-value, and unlike temperature ratings it is additive and comparatively honest — stack two pads and the values add up.

• R 2–3.5 — summer
• R 4–5 — shoulder season, down to around freezing
• R 5+ — winter, or anyone who sleeps cold

The cheapest way to get there: put a closed-cell foam pad (about R 2, and inexpensive) underneath your existing inflatable. It adds insulation, protects against punctures, and gives you something to sit on during the day.

Bags, pillows, tarps and tents — with every temperature and waterproof figure labelled as a manufacturer rating, and the caveats printed next to them.

Layering that survives a twenty-degree swing

You will be too warm at 2pm and too cold at 8pm. Layers rather than one heavy coat.

• Base: synthetic or merino. Never cotton — wet cotton actively pulls heat out of you.
• Mid: fleece or a light down jacket. This is the layer that goes on the moment the sun drops.
• Shell: wind and rain. Wind steals more heat than temperature alone, and a shell over a fleece is dramatically warmer than the fleece alone.
• Extremities: hat, gloves, thick socks. Enormous return for almost no pack space.
• A dedicated dry sleep set that never leaves the tent. Including socks.

Six free things that make a cold night warmer

1. Eat before bed. Digestion generates heat.
2. Go to the toilet first. Your body spends real energy keeping a full bladder warm.
3. Get in warm. Twenty jumping jacks. A bag retains heat; it does not create it.
4. Fluff the bag an hour early. Compressed insulation has no loft.
5. Use the hood drawcord. Most heat loss from a mummy bag is straight out of the top, and most people never cinch it.
6. Hot water bottle at your feet. A sealed bottle of hot water, twenty minutes before you get in, warms the bag itself. Old trick, still the best one.

Dark by six

The shorter day is the change people plan for least. Your two-hours-before-sunset arrival target now means leaving mid-afternoon rather than late afternoon. Evenings are longer, which is lovely with good light and grim without it — a lantern for the table and a headlamp each stop the evening ending at 6:30pm.

It is also the best stargazing of the year: longer nights, clearer air, and you do not have to stay up until eleven to see anything.

The upside, which is considerable

• Bookable sites at short notice, including the good ones
• No mosquitoes
• Cool days that are far better for walking than August heat
• Autumn colour, or spring water levels
• Quiet — often genuinely quiet

Sort out what is underneath you and bring a dry set of clothes to sleep in, and shoulder season is straightforwardly better than summer.
