When our guests are planning their holiday to Loch Lomond, we understand that the weather is a very important factor to take into consideration. There are plenty of jokes about the weather in Scotland, but luckily most of them just aren’t true (honest!). So we’ve put together a post below which gives you an insight into the weather throughout the year here in Loch Lomond and when the best time is to take part in your favourite activity.
Lonely Planet states that it rarely gets too hot or too cold in the Loch Lomond area; we have four distinct seasons of spring, summer, autumn and winter, each with their own special character and charm (which you can sometimes experience all in one day!) As the saying goes, ‘there is no such thing as bad weather, just bad clothing’, so it pays to be prepared.
Spring sees the days starting to lengthen and the average temperatures rising from around 9° C in March to 14° C by mid-May. These months are usually amongst the driest of the year, with just 71mm of rain falling in March and 65mm in May, so they are the ideal time to get out and about and enjoy our stunning scenery.
There are numerous hiking trails to enjoy, or you can hire bikes. Try your hand at fishing or take a ferry trip to Inchcailloch island, part of the Loch Lomond National Nature Reserve, which is carpeted with bluebells in April and May.

June, July and August are the warmest months of the year for Loch Lomond weather, with daytime highs reaching around 19° C and comfortably cool evenings with average temperatures of between 10 and 12° C. The summer is ideal for water sports, including water-skiing, kayaking and swimming and the long light evenings are perfect for whiling away the time fishing on the lochside or riverbank. The summer is also the season for festivals and Highland Games: the Loch Lomond Highland Games and the Luss Highland Gathering are both held in July.
September, October and November see temperatures starting to drop back, from an average of 16°C in September to around 9°C in November, but the shortening days bring glowing light and golden and red leaf colours. Autumn is a very popular time of year to visit Loch Lomond, you can take a guided nature walk to spot rutting red deer or enjoy a cruise on the loch. Around half the days during autumn will see some rainfall, but even if the weather is wet there are plenty of fun things to do.
With snowy mountainsides above the gleaming waters of the loch, the winter landscape around Loch Lomond is hard to beat. Average daytime temperatures range from 8°C in December to 6° C in February and rainfall amounts are around 250mm a month; this may sometimes fall as snow, especially at higher altitudes. In winter, the roads are quiet, so it is the perfect time to go for a cycle ride or car tour, then warm up over a pub lunch by a log fire.
If you are going climbing or planning a hill walk, or even if would just like to know what the weather in Loch Lomond will be like when you arrive, we would recommend checking the Met Office or BBC as these are generally the most reliable.
