Patio awnings are a brilliant way to extend your living space outdoors, creating shade in summer and shelter in autumn showers. But one of the most common questions we hear at Outside Structures is: “Can I use my awning in the rain or during windy UK winters?” 

The short answer is: yes, but with limits. Awnings are designed to withstand certain weather conditions, but they’re not indestructible. Understanding wind classes, the Beaufort scale, and safe use in rain will help you get the most from your awning while keeping it in top condition.

Awnings in Rain, What to Expect

Most high-quality awnings can cope with light to moderate rain, provided they are angled correctly to allow water runoff. However:

·      Pooling is the risk: If rainwater collects on the fabric, it can cause sagging or even damage.

·      Correct pitch is key: We recommend at least a 14° slope so water drains away.

·      Fabric care: Water-resistant, not waterproof, fabrics are treated, but prolonged heavy rain can eventually soak through.

👉 In heavy downpours, retracting the awning is always the safest choice.

Awnings in Wind, Wind Classes & the Beaufort Scale

Every quality awning is tested to a wind resistance class under European Standard EN 13561.

·      Class 2 (typical domestic awnings): Safe up to around 28–37 km/h winds (Beaufort force 4–5: moderate breeze to fresh breeze).

·      Class 3 (premium models): Can withstand 38–48 km/h winds (Beaufort force 5–6: strong breeze to near gale).

To visualise:

·      Force 4 (29 km/h): Small branches move.

·      Force 5 (38 km/h): Large branches sway, umbrellas difficult to use.

·      Force 6 (48 km/h): Strong enough to break twigs off trees.

👉 Once winds approach force 5 or higher, retract your awning.

Winter Use, What You Need to Know

·      Retract in storms: UK winters bring gusty conditions, always retract before winds build.

·      Automation helps: Adding a wind sensor ensures your awning retracts automatically if conditions become unsafe.

·      Maintenance matters: Before winter, check brackets, clean the fabric, and ensure the cassette is sealed when retracted.

 Awnings vs Pergolas, A Quick Comparison

Unlike a bioclimatic pergola or fixed canopy, an awning is not a permanent roof. It’s a flexible shading solution best suited to mild conditions. If you want true all-weather use, consider combining an awning with a pergola or canopy system.

Conclusion

So, can you use a patio awning in rain and UK winter winds? Yes, but only within its design limits. Light rain and breezy days are fine if your awning is pitched correctly, but in heavy rain or strong winds, retracting it is essential.
