Climate As with most of the British Isles and Scotland, Fort Augustus has an oceanic climate (Köppen: Cfb) with cool summers and mild winters. Like a lot of the surrounding area, sunshine levels are low at around 1,000 hours per annum and temperatures are unpredictable – Fort Augustus holds the UK's joint lowest May temperature record of . This is the latest point in the run-up to summer that such a low temperature has been recorded, suggesting it can become a frost trap on calm clear nights due to its valley location. That same low-lying topography can also give rise to some high temperatures on occasion – Fort Augustus held the UK daily high temperature record for 16 December for almost 80 years.
