Through the year
Season by season
Spring
Hatches (e.g. olives, mayflies) drive surface feeding; river seasons commonly open in spring.
Summer
Evening and night fishing is most productive once days are hot and bright.
Autumn
Brown trout spawn in autumn to early winter; many rivers close to protect spawning fish.
Winter
Typically closed on rivers. Some stillwaters stay open — check local rules.
Timing varies by location
Seasons are for temperate Northern Hemisphere waters; in the Southern Hemisphere spring falls around September–November. Latitude, altitude and each year's weather shift timing. Closed seasons and size limits vary — always check local rules.
