When planning a trip to Arendal, it's important to consider the changeable weather typical of the Norwegian coast. The key to a comfortable trip at any time of year is layering. Be sure to bring comfortable waterproof walking shoes, as the number of rainy days here is significant, even if the total precipitation isn't very high. A waterproof and windproof jacket will be your best friend, protecting you from sudden rain and cool sea breezes.

If your trip falls during the colder months (roughly October to April), when average temperatures range from -0.3°C to 6°C and night frosts are common, pack warm clothes. You'll need thermal underwear, fleece jackets or wool sweaters, insulated and waterproof outerwear, as well as a hat, gloves, and a scarf. Don't forget warm socks and water-resistant footwear. During the coldest months, such as January and December, average temperatures stay around freezing, so warm gear is especially important.

For a trip during the warmer season (May to September), when average temperatures rise from 11°C to 17°C and maximums can reach 20°C, choose lighter clothing. T-shirts, light trousers, or shorts are suitable for sunny days. However, even in summer, evenings can be cool and rain is still likely. Therefore, a light windbreaker or raincoat, as well as a sweater or fleece, will come in handy. On sunny days, don't forget sunscreen and sunglasses, especially if you plan to spend a lot of time by the water.
