Largemouth begin staging in the high 50s and spawn through the 60s, with the heaviest bedding activity as the water settles into the mid-60s. Every one of those numbers is a water temperature, not a date — which is why the spawn runs six weeks apart on two lakes in the same state.
Keyed to surface temperature, which is what the fish is actually responding to:
| PHASE | WATER TEMP | WHERE THEY ARE |
|---|---|---|
| Winter | Below 50°F | Deep, on the last structure before the channel. Barely feeding. |
| Pre-spawn staging | 50–58°F | Secondary points and channel swings leading into spawning pockets. |
| Pre-spawn move-up | 58–62°F | Shallow flats adjacent to deep water. The most aggressive fish of the year. |
| Spawn | 62–70°F | On beds — hard bottom, protected pockets, north banks warm first. |
| Post-spawn | 70–75°F | Guarding fry, then pulling back to the first break. Erratic, then excellent. |
| Summer | Above 78°F | Deep structure and the shade line. Dawn, dusk and dark. |
The north side of a lake and the north side of every pocket in it warms first, because it takes the most direct sun. Early in the spawn, that is where the fish are — and a week later the same pattern has moved to the south shore. On a big reservoir the spawn is not an event, it is a wave that crosses the lake.
April is the peak spawning month across most of the largemouth range, and treating April as the answer will cost you fish every year. A warm February pulls the whole sequence forward by three weeks. A late cold snap pushes staged fish back off the flats overnight.
The reliable move is to fish the temperature. BassHawk publishes the current reading and its two-week trend for every lake it covers, which is the pair of numbers that tells you which row of the table above you are actually in.
