Weather Guide for Iceland in August
Iceland in August experiences mild but unpredictable weather, with temperatures ranging from 10–15°C (50–59°F)during the day and dropping to 5–10°C (41–50°F) at night. While it is one of the warmest months, the weather can change quickly, bringing a mix of sunshine, rain, and strong winds, especially in coastal areas and the Highlands. Daylight hours are still long, with around 14–18 hours of sunlight, making it ideal for outdoor activities. Rain showers are common, so waterproof clothing is essential. Snow is unlikely except on glaciers, which remain frozen and accessible for guided hikes. With comfortable temperatures and lush green landscapes, August is a great time for hiking, whale watching, puffin spotting, and exploring Iceland’s dramatic scenery.
If It’s Rainy: When rain is in the forecast (the reality more days than not), a waterproof shell jacket or parka is your best friend. Layer it over a cozy, wool sweater and pair it with waterproof pants and fleece-lined leggings. Waterproof hiking boots or ankle boots will keep your feet dry as you explore the muddy landscapes.
If It’s Windy or Extra Chilly: For those days with fierce winds, bundling up is key. Wear a thermal base layer under a chunky knit sweater, and top it with a down jacket or heavy parka. Add a thick scarf, wool hat, and thermal gloves. Fleece-lined leggings or weather-resistant pants will keep your legs warm, and tall insulated boots will provide extra protection against the cold.
If It’s Cold and Clear: Iceland’s crisp, sunny days are ideal for packing in adventures so you’ll want to layer for warmth while still feeling comfortable while active. A thermal base layer under a fleece sweater works perfectly. Pair this with insulated leggings or hiking trousers and waterproof ankle boots. Add a beanie, gloves, and sunglasses to protect yourself from the bright summer sun.
Other Things to Pack for Iceland in August
Portable Charger: A portable charger is another must-have. With your phone constantly in use for navigation, photos, and making reservations, it’s easy for the battery to drain quickly. A power bank will ensure that you don’t run out of power when you need it most, especially during long days of sightseeing. Plus, how will you document your fabulous outfits in beautiful locations if your phone is dead?
Compact Backpack: Additionally, a lightweight, backpack can come in handy for shopping or carrying extra items as you explore or hike. A spare bag will allow you to pick up some unique souvenirs or delicious pastries from local markets without worrying about your other belongings.
