The weather in Wester Ross is occasionally wet and windy, yes - but when it's good, it's VERY good! The weather forecaster below is from Two Lochs Radio (in Gairloch). Gairloch is roughly in the centre of the coastal strip of Wester Ross, so this should be a fairly good indicator of how the area as a whole is behaving!
And here is the weather forecast for the next 5 days (we call this a "good guess"). Just type in the location you require in the wee box at the top right corner of the five day forecast.
