The British Isles feature a marine, temperate climate that experiences significant amounts of moisture, and surprisingly, has temperatures 20 degrees higher than expected for its geographic location. As a result, the weather is fairly comfortable, even during the winter months.
Although temperatures remain somewhat constant year-round, most British Isles cruises are offered April through October during the peak travel season. The busiest time to travel to the British Isles is during the months of July and August. Most sailings are seven to 28 nights in length, and depart from major European cities such as London, Amsterdam or Copenhagen. If you’re thinking of traveling to the British Isles and would like to avoid the summer crowds and possibly secure a lower rate, you may want to consider traveling during the shoulder seasons in the spring (April and May) and in the fall (September and October) when there are fewer tourists packing historical sights and famous landmarks.
