Without question, the best time to visit Portland is during the months of summer, from June through until September, when the weather is at its best, with low rainfall, low humidity, and temperatures of between 20C and 30C on most days. Portland has a similar climate to an English city, ensuring that the surrounding countryside is green and pleasant.
Portland hosts festivals throughout the summer months, and the largest takes place at the start of autumn, the North by Northwest Fest where you can hear the largest bands in the country playing the latest tunes.
