Kuwaiti anglers spend a lot of time reading wind forecasts and very little reading the water itself. That is backwards. Air temperature and water temperature are two different numbers, and on the same day they can disagree by ten degrees or more.
Water holds far more heat than air for the same volume, so it takes much more energy to shift its temperature and it gives that heat back slowly. Air answers the sun and the wind within an hour; water answers over days and weeks, so a heatwave does not warm the sea straight away and a cold snap does not cool it straight away. Wind and shallowness speed that up: wind mixes the warm surface layer down, and shallow water heats faster because there is less of it.
Kuwait Bay is shallow, semi-enclosed and flushes slowly. In summer the water along the shore runs warmer than the open Gulf a few kilometres out, and it swings harder between morning and afternoon. Beyond the islands the water is deeper, better mixed and steadier, and in autumn it cools ahead of the bay. In practice: in the bay, water temperature is a fast local number; offshore it is a slow seasonal one.
Air peaks in the early afternoon. Water peaks later and keeps its heat into the night, so the coolest water on a summer day is at first light, and the coldest hour of a winter day is a few hours after sunrise, not at dawn. On a 40°C day in July, water at 5 am can still feel cool to your hand.
Seasonally the same thing happens: the hottest air lands in July and August, yet the water keeps climbing into September, and in winter it stays cold well into March.

Fish live in the water number, not the air number. A shallow flat that stayed cool overnight feeds fish at dawn in July; by mid-afternoon it is hot and empty. In winter a bright calm day can still mean cold water, so fish slow down and sit on shallow sun-warmed ground. Read the water; let the air only tell you how you will feel.
Cold water is the bigger risk and Kuwaiti boaters underestimate it. Winter water of roughly 15–18°C pulls heat out of the body far faster than air at the same temperature, so going over the side in February is a genuine hypothermia risk. Summer is the other edge: shallow bay water gets hot enough to make wading unpleasant and to raise the risk of heat exhaustion on deck.
