Awnings are usually water-repellent to allow you to sit under them even in the rain, but they are not exactly waterproof. While your awning will protect you against light to moderate rain, you shouldn’t use it during heavier storms because it can become damaged due to pooling water or the fabric stretching. We always say to use your best judgment about whether you think it’s safe to be outside under your awning. If it’s a light drizzle, you should be fine. If it’s hailing, you’re probably better off indoors.
