Condensation or a leak? Start by checking where the water is

Notice the pattern

Fine moisture spread over an inside surface can be condensation. A repeated wet patch beneath a seam, damaged area or pooling point may need a closer look. Neither pattern alone proves the cause. Record weather, ventilation and the exact location rather than immediately applying sealant everywhere.

Reduce avoidable moisture

Use the vents as the tent maker intends, and maintain the correct separation between inner tent and fly. Avoid pressing bedding against damp fabric. Keep wet outer clothing separate where the site and weather allow. Never cook or operate fuel-burning equipment inside a tent to dry it.

Check the pitch

A correctly fitted groundsheet should not collect rain beneath the tent. Inspect fly tension, attachments and any places where water can pool. Follow the specific pitching instructions instead of adding more tension indiscriminately. Water can travel along fabric, so the drip location may not be the entry point.

Make a useful note for the next trip

• Time the moisture appeared and whether it was raining.
• Which surfaces were wet: fly underside, inner mesh, floor or a seam.
• Vent positions and whether bedding touched the outer fabric.
• Photographs of the area when wet and again when dry.
• The result of a careful inspection following the manufacturer’s guidance.

After the trip

Dry the tent completely before storage and check the care instructions before using cleaners, proofing products or seam sealers. If the problem repeats, send the maker your notes and photos. Good observations are more useful than treating every damp tent as a failed waterproof coating.
