Apart from England and Wales, Ireland and Scotland usually top the lists of the UK itineraries. Though we are accustomed to seeing them depicted as constantly cloudy and rainy, the reality is far from that. In fact, there are many periods of the year that actually make up for the best times to visit Ireland and Scotland. 
When To Come To Ireland and Scotland
These two countries are predominantly influenced by the Atlantic Ocean making their climate mild and pleasant all year round. Being rather hilly, they are well protected against strong winds and severely low temperatures. Still, weather in Ireland and Scotland can be volatile and unpredictable at times. Although certain seasons are ideal when you want to escape the crowds, other visitors will surely appreciate the hustle and bustle of the busiest seasons. Unsurprisingly, both Ireland and Scotland experience dramatic changes in appearance as the seasons change and each one carries its own distinct charm with it.

Summer in Ireland and Scotland
In Ireland, temperatures in summer rarely exceed 68°F and it’s predominantly pleasant and sunny. Summer months cover the period between May and July. During that time, you will be able to experience extended hours of daylight. As a matter of fact, the summer solstice in the Northern Hemisphere happens around June 21st and it signifies the beginning of “the longest day” - the time when the sun rises as early as 5 am and doesn’t set until 10 pm. It’s a perfect opportunity to go out and about without the fear you will be caught out in the darkness. Summer in Scotland also spans from June to the beginning of August and the temperatures rarely go above 63°F. Extended twilight and pleasant long summer days are ideal for a relaxing vacation. What’s more, the far north of Scotland never actually gets completely dark at this time of year. These extra hours of daylight make summers in Scotland the best time of year for a perfect summer getaway. 
Spring in Ireland and Scotland
Spring is possibly one of the best times to visit both countries. Not only does everything start to blossom and flourish but the temperatures also range from 46 to 54°F, making these countries highly favorable for exploration and adventures. The average temperature in Ireland in spring is a bit chillier than in summer, especially in the evening. On the other hand, the chances of rain are least likely during spring, with the biggest number of sunny days in store. Scottish springs are no exception to this. Spring in Scotland begins in late March and ends in May while the temperatures are just enough to get the snow to start melting. Though Scotland, just like Ireland, tends to have unpredictable changes in weather conditions, the risk pays off. Despite popular belief, the driest months are actually April and May, making this period an ideal opportunity to wander off in the Scottish Highlands. 
Autumn in Ireland and Scotland
Autumn in these two countries covers the period between September and November. This is the time when temperatures rarely go above 62°F in September and drop to 39°F in November. The days are a bit shorter than in summer and spring and there are more rainy days too. Still, autumn brings some magical touch with it which is why it’s one of the best times to visit Ireland and Scotland. If you’re a Game of Thrones fan, visiting Northern Ireland in autumn will surely bring you closer to Westeros. Not only is this part of Ireland brimming with the Seven Kingdoms localities but it’s also magical during autumn. What’s more, autumn in Ireland marks the beginning of the harvest season so festivals become every fall’s highlight. Waterford Harvest Festival and Mount Stewart Gardens put on incredible shows to celebrate the beginning of autumn. 
Winter in Ireland and Scotland
Believe it or not, Irish winters are actually the driest of all seasons. They cover the period between December and February with maximum average temperatures no higher than 46°F. There is no much snowfall throughout the period but there are also fewer hours of daylight. With the winter solstice occurring around December 21st, the sun doesn’t rise until 8 AM and sets very shortly, around 4 PM. Scottish winters are pretty similar, starting around the end of November and lasting until early March. Winters are surprisingly mild unlike in other places on the same latitude (Norway, Canada, or Alaska). The temperatures stay around 44 °F during the day and rarely drop below zero, even in the evening. The South of Scotland is generally warmer than the North although extreme winters are highly rare throughout the country. 
What Clothes to Bring when Visiting Ireland and Scotland
The Scotts swear by one adage: ‘There’s no such thing as bad weather, only the wrong clothes!’ Weather in Scotland varies from region to region and may change several times in a single day. For this reason, what you plan to do while there makes all the difference. However, there is one rule of thumb and that is - layers. 
So, What’s the Best Time to Visit Ireland and Scotland?
Obviously, it all depends on what you want to do and what you want to see. Every season in these countries carries its own perks and provides visitors with opportunities to embark on different adventures. Although the weather is more likely to be volatile during certain seasons, the beauty of these countries will surely make up for that no matter when you visit them.
