Seaside and Gearhart are year-round destinations. Summer is the most popular season. Temperatures range from the 60s and 70s during the day to the 50s at night, though the ocean is always too cold for swimming unless you’re especially hardy or have a wetsuit. Spring and fall are cooler and rainier than summer, though both seasons are still delightful in this area. Winter is not terribly cold, ranging from the 40s and 50s in the day to the mid-30s at night. Many of the attractions are still open in winter.
