Flies by Month – Stillwater (UK Seasonal Guide))

Choosing the right flies for stillwater fishing changes throughout the year as water temperatures, insect life, and fish behaviour shift with the seasons.

This page brings together our month-by-month stillwater fly selections, curated specifically for UK stillwaters. Each monthly collection reflects what is typically hatching at that time of year, along with the subsurface food sources that continue to produce fish when surface activity is limited.

Unlike generic “best fly” lists, these selections are built from on-the-water experience. As a specialist fly fishing retailer and coaching business, we spend thousands of hours each year fishing UK stillwaters and advising anglers on fly choice, depth, and presentation. That experience shapes every collection on this page.

Use this guide to explore which flies are most effective throughout the season, whether you’re fishing cold winter water, spring buzzer hatches, peak summer terrestrials, or autumn feeding patterns. Each month links to a dedicated stillwater collection with more detailed guidance.

If you’re unsure which flies are best for your local water or current conditions, we’re always happy to help.
