Best time to fish for bass: by hour, season and water temperature

When to catch largemouth and smallmouth bass: the best times of day, a season-by-season water temperature guide, and how weather, moon and solunar windows fit in.

Bass are the most popular freshwater game fish in the US, and one of the easiest to time once you know what drives them: light, water temperature, and weather. Here's when to go.

Best time of day to fish for bass

Early morning, from first light to about two hours after sunrise, is the most reliable window all year.
Evening, the last two hours before dark, is just as good in summer and fall.
Night is excellent in the heat of summer, especially on clear, pressured lakes.
Midday is best in early spring and late fall, when the sun warms the shallows. In summer, midday bass go deep or under cover.

Overcast days stretch the morning bite across the whole day.

Best season: a water temperature guide

Water temperature	Phase	What to do
Below 50°F (10°C)	Winter	Fish slow and deep; the warmest afternoon hours are best
50–60°F (10–15°C)	Pre-spawn	Often the best fishing of the year. Bass feed up on points and channel edges near spawning flats
60–75°F (15–24°C)	Spawn	Bass on beds in the shallows; check local rules on bed fishing
70–80°F (21–27°C)	Post-spawn and early summer	Topwater mornings, bass move to grass and points
Above 80°F (27°C)	Summer	Dawn, dusk and night; deep structure at midday
Falling from 70 to 55°F (21–13°C)	Fall	Bass chase baitfish into creeks; long feeding windows

Smallmouth follow a similar calendar but tolerate cooler water and like rock, current and clear water.

Weather that turns bass on

The day before a cold front, with falling pressure and building wind, is often the best of the week.
Wind on a point or bank pushes baitfish and breaks the surface: fish the windblown side.
Light rain is great for topwater. See fishing in the rain.
Post-front bluebird skies slow the bite: slow down and fish tight to cover.

The pressure side is explained in barometric pressure and fishing.

Moon phase and bass

Many bass anglers believe the spring full and new moons trigger waves of spawning when water temperature is right, and tournament anglers often watch the moon in the pre-spawn. In summer, bright full-moon nights are popular for night fishing.

Use the moon to choose days and solunar windows to choose hours: a major period at sunrise on a pre-front day is about as good as bass fishing timing gets. The phases are compared in best moon phase for fishing, and the 2027 spring moon dates are in the solunar fishing calendar.

Quick plan

Check water temperature to know the seasonal phase.
Pick the best-rated day with stable or falling pressure.
Fish the solunar window that overlaps sunrise or sunset.
Adjust depth and speed to the season.
