Tarpon fishing is highly dependent on the location. But in general, the best time of year for tarpon fishing is during the warmer months when the water temperatures are between 75-85°F (24-29°C). In Florida, where Lake Tarpon is located, tarpon fishing is usually best from late April to early August.   During this time, tarpon moves into shallow waters to feed, breed, and lay their eggs. They are also more active and aggressive during this period, making them more likely to strike at bait or lures.
