We are now already noticing a change in weather in Scotland as we move towards the autumn months. The early mornings are cooler and the days are getting shorter. With this the water temperatures will also be cooling. If you are planning a salmon fishing holiday in Scotland in the upcoming weeks then you may need to consider using larger flies. Once the water temperature drops this can often be the order of the day. In early autumn when salmon fishing, using bigger flies, often seems to bring out an aggressive response from the salmon. So, if you do have a Scottish salmon fishing holiday booked this autumn don’t forget those bigger flies!
