Temperatures

During the spring, summer and autumn months (ie the sailing season) the dominant factor in controlling temperature is latitude – the further north one sails the greater the probability that temperatures will decrease. 

Typically, the mean daily temperature in Oban (17-20 degrees centigrade) on the west coast is between 3 and 4 degrees cooler than that experienced in London during the summer.  There is also a slight west east gradient in temperature arising from the influence of both the North Sea and the near continent. 

During the summer months east coast temperatures are typically 1 or 2 degrees warmer than those on the west, whilst in the winter and early spring the Gulf Stream ensures that this pattern is reversed and west coast temperatures are significantly higher – so much so that they often exceed those of southern England.
