What should I pack for a holiday in the Azores during September?

She Get's Around Make sure you pack plenty of layers, with the changing weather you need to be prepared for everything. In the space of an hour you can go from wearing shorts and T-shirt to needing long trousers, a warm jumper and a waterproof. So pack plenty of layers and clothes for outdoor activities. The Azores includes many beautiful hiking spots and some of the best wild swimming and hot springs I have ever seen. So hiking boots, swimming things and a waterproof are all essentials to make the most of what the islands have to offer. Answered by She Get's Around

What's great about the Azores in September?

She Get's Around September is a great time to go Whale watching. The sea is calmer and you are likely to see some migrating whales passing through. You will likely get to see some dolphins playing together beside your boat too. With the weather slightly warmer it is a great time to explore the different ocean swimming spots. The water is a reasonable temperature and due to most of the island being covered in volcanic rock, they have created natural swimming areas, with steps into the ocean for sea swimming amongst the rocks.
