"Scotland Golf and Weather"
...The locals are fond of saying that Scotland doesn’t have a climate, just weather. If you don’t like it, just wait a few minutes. It is a national joke that, in Scotland, one can experience four seasons in one day.
Weather can be a challenge in Scotland, but it is not as bad as some would have you think. I have spent countless glorious days on Scottish courses under skies that are equal parts blue and billowy white. The long summer evenings, a blessing of Scotland’s high latitude, can be quiet and still, inviting the golfer out to a peaceful round after supper. The moderate breeze that is fairly common, especially on links courses, adds another interesting element that must be factored into your game, along with the slope of the landing area and the break of the green.
What can you expect? Probably the only thing that one can say with certainty about the weather in Scotland is that it is unpredictable. Generally speaking, the west coast of Scotland is wetter but warmer than the east. It benefits from the effects of the gulf stream that wraps around the North Atlantic bringing warmer currents to lap on western shores. The east is dryer but often receives its weather directly from the North Sea that can add a real nip to the air. This being said, the temperatures across Scotland are never extreme. You never encounter either very hot or very cold conditions. Records show us that the warmest months are July and August with average highs of 65º. June averages 63º and September 61º. May and October are 58º and 54º respectively.
