Shelter

Site a tarp for wind and rain

Siting a tarp means choosing ground and natural shelter that help your pitch shed wind and rain. You use this skill before unpacking when camping in wet, windy, or changeable weather. Favor a sheltered, gently sloping site with a sleeping area outside any runoff path. Good placement does more for your comfort than trying to overcome an exposed or poorly drained site with a tighter pitch.

Topic summary

Key takeaways

Your sleeping area sits outside hollows, channels, and visible runoff routes.
The site has natural wind shelter and no apparent overhead or upslope falling hazards.
The low, closed end faces the wind, and gusts do not blow directly into the sleeping area.
Tarp panels slope without pockets, and their drip edges discharge beyond your sleeping area toward lower ground.
Avoid: Choosing a flat-looking hollow invites pooling water; move to slightly raised, gently sloping ground.
Avoid: Treating any treeline as safe overlooks unstable trees and exposed edges; inspect the trees and choose shelter within a sound stand.

Safety: Stay out of dry streambeds, flood channels, and places where rising water could cut off your exit. A tarp does not provide lightning protection; if thunderstorms threaten, avoid exposed terrain and seek a substantial building or enclosed hard-topped vehicle when available.

Step-by-step

Skip valley bottoms — cold air pools there overnight.
Why: 1. Skip valley bottoms — cold air pools there overnight. Dense, cool air drains downslope and collects in low ground, making these sites colder and often damper than nearby slopes.
Skip ridge tops — wind hammers exposed sites.
Why: 2. Skip ridge tops — wind hammers exposed sites. Exposure increases wind-driven rain and loads on fabric and anchors, making a dry, stable pitch harder to maintain.
Look mid-slope, back into a treeline, with the closed end into the wind.
Why: 3. Look mid-slope, back into a treeline, with the closed end into the wind. A sheltered position within sound trees reduces wind exposure, while a low, closed windward end helps keep gusts and driven rain out of your sleeping area.
Check overhead for widow-makers: dead branches, leaning trees, loose rock.
Why: 4. Check overhead for widow-makers: dead branches, leaning trees, loose rock. Scan above and around the entire pitch because falling limbs, unstable trees, or rock can reach you from beyond the tarp's footprint.
Pitch the low end downhill so water runs away, not under your bag.
Why: 5. Pitch the low end downhill so water runs away, not under your bag. On a suitable gentle slope, this directs roof runoff toward lower ground, but only if the drip edge lies beyond your sleeping area and no uphill runoff crosses the site.

Common mistakes

Choosing a flat-looking hollow invites pooling water; move to slightly raised, gently sloping ground.
Treating any treeline as safe overlooks unstable trees and exposed edges; inspect the trees and choose shelter within a sound stand.
Facing the open end into the wind admits driven rain; turn the low, closed end toward the prevailing wind.
Assuming a downhill pitch stops all runoff ignores water arriving from above; check uphill for channels, washed soil, and debris lines before pitching.
Forcing a pitch where downhill drainage conflicts with wind protection leaves one problem unsolved; choose another site or adjust the pitch so both the windward face and runoff are controlled.

Troubleshooting

If water flows toward or beneath your sleeping area, then move to higher, better-drained ground rather than digging a diversion trench.
If gusts drive rain through the opening, then lower the windward edge and reorient the pitch, or relocate if the site remains exposed.
If water pools on the tarp, then adjust its slope and tension until every panel drains beyond the sleeping area.
If anchors pull loose or the tarp repeatedly collapses in gusts, then lower the pitch and improve the anchors, or move to a more sheltered site.

Field practice drill

Spend about twenty minutes comparing three nearby sites in safe weather. At each, identify the wind direction, uphill runoff routes, drainage, and overhead hazards; then choose one and pitch with the closed end windward and the low end draining downhill. Lie in your intended sleeping position to check coverage and drip-edge clearance, then pack up without leaving trenches or damaged vegetation.

Indicators of success

Your sleeping area sits outside hollows, channels, and visible runoff routes.
The site has natural wind shelter and no apparent overhead or upslope falling hazards.
The low, closed end faces the wind, and gusts do not blow directly into the sleeping area.
Tarp panels slope without pockets, and their drip edges discharge beyond your sleeping area toward lower ground.
