While just about any month is great to visit Scotland and Ireland, there are a few prime times of year worth considering. Here’s what to expect, according to our destination experts:

Spring: March through May is a wonderful time to visit the region! The countryside comes alive with flowers and shades of green, and the days grow longer with 13 to 16 hours of daylight, giving you more time to explore. You can expect fewer crowds but be aware of the busier Easter holiday and Saint Patrick’s Day. Be sure to bring a raincoat and layers because the weather changes quickly here, with temperatures ranging from the 40s to mid-50s°F (4-13°C).

Summer: Summer is one of the most popular times of the year to visit Scotland and Ireland, with tourists coming from across the globe to take advantage of the warm weather and flurry of festivals and activities. Both countries come alive with vibrant landscapes, long daylight hours, and a plethora of outdoor activities. In Scotland, you can explore the majestic Highlands, visit historic castles, and enjoy the bustling atmosphere. Edinburgh, in particular, is bustling with The Royal Edinburgh Military Tattoo and the famous Fringe Festival, which bring thousands of people to the city in August alone. The weather is generally mild, with temperatures ranging from the high 50s to mid-80s°F (10-29°C), perfect for hiking and sightseeing. However, temperatures can still dip at night and in the morning, so we recommend packing in layers just in case. Meanwhile, Ireland offers lush green countryside, stunning coastal views, and lively cities. Summer is also festival season in Ireland, with events celebrating music, arts, and local culture. With the sun setting as late as 10 p.m. and rising as early as 4 a.m., you have plenty of time to soak in the beauty and charm of these Celtic lands. Cities, attractions, and restaurants are at their busiest, so if there is anything you want to see or do outside of the tour, we recommend making reservations or booking tickets in advance. Just be prepared for occasional rain showers and pack a light waterproof jacket to stay comfortable.

Fall: In recent years, September has become one of the most popular times to visit Ireland and Scotland, making top sights busy. By October, tourism begins to slow down, and November is relatively quiet, making these months ideal for those wishing to take advantage of fewer crowds. Fewer hours of daylight and cooler temperatures make late September and October a little less hospitable than the summer, but the changing colors of the foliage make the landscape vivid and inviting. With fewer crowds in October and November, take your time at major sites. Expect more rain showers during this time in both countries, and be sure to pack warm, waterproof layers. Daily temperatures average in the mid-40s to 50s°F (7-13°C).
