Fishing Lac Seul in the Spring
| Month | Avg. Air Temps °F (Hi/Lo) |
| March | 31° / 8° |
| April | 47° / 25° |
| May | 62° / 39° |
The spring is a great time to fish. During the walleye opener, the better bite is usually up in the Ear Falls area since this is a major spawning destination on Lac Seul. Many anglers will come here for the awesome spring walleye fishing, so plan on seeing lots of boats and lots of big walleye during this time of year. You can still catch walleye and pike throughout the entire lake though. Fish the rocky shorelines and islands with a mix of shallow and deep water. Spots that have some current running into the lake are awesome spots to fish in the spring as well. Don’t forget about the smallmouth bass either. The end of May brings a lot of smallmouth bass into the bays and along the shorelines. This time of year is usually your best chance to find smallmouth bass on the west end of the lake since their numbers are much lower than on the east end of the lake.
Fishing Lac Seul in the Summer
| Month | Avg. Air Temps °F (Hi/Lo) |
| June | 71° / 50° |
| July | 76° / 55° |
| August | 74° / 53° |
Early in the summer, there will still be a lot of fish shallow, so target the rocky shorelines of the main land and around the islands. Some of the bays will still offer some very good fishing too. Once warmer weather sets in, the fishing will almost always be better on the main lake points, islands and offshore structure.
Fishing Lac Seul in the Fall
| Month | Avg. Air Temps °F (Hi/Lo) |
| September | 62° / 44° |
| October | 47° / 33° |
| November | 30° / 17° |
In the fall, the fish are gorging themselves to get ready for the winter. Plan on finding plenty of fish in the shallows as well as deeper water. Some fish move shallow in the fall, but plenty will stay deep as well. As the end of fall nears, the better bite will usually be in deeper water.
Fishing Lac Seul in the Winter (Ice Fishing)
| Month | Avg. Air Temps °F (Hi/Lo) |
| December | 15° / -2° |
| January | 10° / -10° |
| February | 17° / -5° |
Lac Seul is pretty remote, however, there are some businesses still catering to anglers through the winter which makes it a little easier to plan a trip here. The lake is huge and the fishing can still be great for walleye and pike as long as you have the equipment to handle these colder temperatures.
