The best time to go to Arrieta is during the shoulder seasons of spring (April to May) and autumn (September to October) for pleasant weather without the peak summer crowds.During these months, you'll experience warm, sunny days great for enjoying the beaches and outdoor activities, but with fewer visitors than in July and August. This means you can often find better deals on accommodation and flights, and popular spots aren't as busy. The sea temperatures are also very agreeable for swimming.For those looking for the warmest weather and don't mind more people, July and August are excellent. The island is lively, and temperatures are at their highest, making it ideal for beach holidays and water sports. However, prices for hotels and flights will be higher, and you'll need to book well in advance.If you're after a winter escape with mild temperatures, November to March offers a good option. While it's slightly cooler and there's a higher chance of rain, it's still considerably warmer than much of Northern Europe, making it a popular choice for those seeking winter sun.
