Water temperatures can have a huge impact on snook. In colder water, snook don’t do very well at all and it is common to have winter fish kills if water temperatures drop into the mid-50s. As water temperatures drop into the low-60s and upper 50s, the bite will slow down tremendously. As water temperatures cool during the winter months, snook will seek out the warmer water temperatures in the tidal creeks, inlets and canals.
Snook do very well in warmer water temperatures. Snook will be very active with water temperatures ranging from the 70s up into the low 90s.
