The best time to go to Horten is during the summer months, from June to August, when the weather is at its warmest and the days are longest.During this period, you can expect average temperatures ranging from 18°C to 22°C, making it pleasant for outdoor activities such as exploring the coastal paths, visiting the Norwegian Naval Museum, or enjoying a boat trip on the Oslofjord. The extended daylight hours, with the sun setting late in the evening, provide ample time for sightseeing and relaxation. This is also when many local festivals and events take place, offering a chance to experience Norwegian culture.For those who prefer fewer crowds and slightly cooler temperatures, late spring (May) or early autumn (September) can also be a good choice. The landscapes are beautiful with blooming flowers or autumn colours, and the weather is often still agreeable for exploring.
