At what temperature do crappie spawn? Crappies will spawn when water temperatures reach between fifty-eight and sixty-six degrees F. However, when the temperatures start reaching between forty-seven and fifty-four degrees F, the crappies will start moving closer to the spawning areas where they will make the nests.f the water temperatures warm to the right degree for spawning and suddenly drops, the spawn will not happen until the water warms again. Sometimes a female will not lay the eggs if the temperature warms and cools too many times. She will simply absorb the eggs and miss the spawn altogether.
