May in Maine is when the waters come alive. As the ice retreats and the landscape turns green, anglers across the state gear up for one of the most exciting times of the year. Whether you’re casting from a quiet lakeshore or wading into a mountain stream, May offers a perfect mix of opportunity, challenge, and natural beauty.
Why May is Prime Fishing Time in Maine
Maine’s diverse freshwater systems—rivers, lakes, ponds, and streams—start to warm in May, sparking activity in coldwater species like brook trout, landlocked salmon, and lake trout (togue). At the same time, warmwater species such as smallmouth bass begin to stir in southern and central Maine waters.
The spring melt brings high flows and oxygen-rich water, drawing fish into shallower, more accessible areas. This makes May ideal for fly fishing, trolling, and shore casting alike.
Top Species to Target
Brook Trout
These native beauties thrive in cold, clear water. Stocking efforts across the state mean even beginner anglers have a great shot at landing a few. Look for them in small streams and stocked ponds in the early part of the month, especially near inlets and outlets.
Landlocked Salmon
In larger lakes like Moosehead, Sebago, and Rangeley, salmon cruise near the surface in May. Trolling with smelt-imitation lures or fly fishing with streamers can produce great results.
Lake Trout (Togue)
These deep-dwelling predators move up in the water column during spring. Troll near drop-offs or try jigging in 20–40 feet of water. Lakes like Sebago and East Grand are top destinations.
Smallmouth Bass
In southern Maine, bass fishing begins heating up in mid-to-late May as fish prepare to spawn. Target rocky shorelines and submerged structure with jigs or soft plastics.
