More about choosing river flies through the year
River conditions change throughout the year. Water temperature, flow, insect activity and fish behaviour all influence which flies to choose and how to fish them.
Our monthly collections provide a practical starting point. Adjust your choice to the conditions on the day, paying attention to insect activity, feeding depth and presentation.
For more practical advice, explore our Fly Fishing Knowledge Base, or contact our team for help choosing.
