Fishing for snook is usually better during low light conditions than during the middle of the day when the sun is out. However, the tides play a bigger role in how well the fish will be biting. On a bright sunny day during the tidal change, the fishing can still be very good, but it will usually be a better bite in the early morning, late evening and at night. One of the advantages to fishing when the sun is out is that you will have more sight fishing opportunities. However, sight fishing for snook on a sunny day is not the most effective way to target these fish.
