Most anglers check the air temperature and call it a day. The real driver behind biting fish or quiet water is water temperature, not air. The air can feel mild while the water sits cold, and the reverse happens too. Fish follow the water that keeps them comfortable, so knowing water temperature tells you where to look and why nothing is biting.
Water reacts to sun, wind, and tide. Shallow water changes fast: it warms under the morning sun, then cools when the tide drops. Deeper water moves slowly, and as seasons shift it splits into layers. That is why the same spot can fish completely differently at dawn and in the late afternoon.
Every species has a range where it feeds normally. Inside that range, fish are active and willing to take bait. Outside it, they drop deeper, move away, or shut down. They are not impossible to catch, but your effort per fish climbs hard.
The working rule is simple: colder means deeper, hot also pushes deep, and mild means closer to the surface. In Kuwait's cold season, fish look for the warmest deep water, so expect them near drop-offs and the bottom. In spring, water evens out and fish move toward the shallows and the coast, which is prime light-tackle time.
In summer, heat drives fish deep during the day, and they come shallow at night or at first light. Change your timing before you change your spot. In autumn, water cools gradually, fish become active again and spread over wider ground, so results depend less on holding one fixed location.
The table below is a practical guide built on Kuwait's seasons, not exact numbers. Read it as a general direction, and always check the tide and sea state before you head out.
This is the habit that pays off most. Write the time, the water state, and the result after each trip, and you build a personal database of your own water. Note the water temperature as best you can estimate it, the bait, the depth you fished, and the exact time. After a while a clear pattern shows up: which time and which depth produce in each season.
That is where the B7R app fits in. It gives you tide tables for Shuwaikh and Shuaiba ports plus sea state, along with a catch log, seasons, a fish guide, and navigation tools. Log your notes after every trip and compare across seasons, and you will know exactly when and where fish are most active in your water.
