The density of water increases as the temperature decreases and approaches a maximum at 4oC. After this point the density decreases until 0oC at which point the water changes to ice.
The density and the buoyant force of the water therefore increases until the 4oC point at which time it decreases slightly:
Temp ( °C ) : Density (g/cm3)
0 : 0.9999
4 : 1.000
20 : 0.9982
40 : 0.9922
60 : 0.9832
80 : 0.9718
Using Lake Superior as an example, the surface water temperature varies between 20oC July/August and slightly above 0oC in December/January. The water provides 1% more buoyancy (it's density is 1% higher) in winter.

Does the ground absorb more water in the summer or the winter?
it absorbs more in the summer
Is there likely to be more water vapor in the air in summer or winter?
in summer.
Why do feel more thirsty in summer than winter?
Because they do not sweat as much in the winter than they do in the summer.
Why does it feel more humid during the summer than during the winter?
The cold in winter causes the humidity to drop by condensing it out. The heat in summer can cause the humidity to rise by evaporating more water from nearby bodies of water.
Why is air more buoyant than water?
Air is more buoyant than water because air is less dense than water, and everything the thing that is less dense is always more buoyant than what is more dense than it.
Is more oxygen produced in the winter or summer?
Oxygen is produced by living plants. Plants use Carbon Dioxide, Water and Sunlight to make Sugars and Oxygen. As sunlight is required and there is more of this in summer, more oxygen is produced in summer than winter.
Why does buoyancy force change in the fluid temperature high temperature less buoyancy low temperature high buoyancy now why is that?
Buoyant force is directly proportional to the mass of the liquid that is displaced by an object that is submerged in it. The mass of a certain volume of a liquid is directly proportional to the density of that liquid. The more dense the liquid is, the greater is the buoyant force. For water that is over 4 degrees Centigrade in temperature, the warmer the water, the less dense is the water. In other words, warm (summer) water is less buoyant than is cold (winter) water, because the density of warmer water is less than is the density of cooler water. Similarly, salt water is more buoyant than fresh water, because the density (in grams per cubic centimeter, or pounds per cubic yard) of salt water is greater than is the density of fresh water.
Why can a ship load more in the summer than winter?
in summer water is warm as warm water provides less buoyancy being less dense than cold water
Are hot water heater problems more common in the summer or winter?
Hot water heater problems are more common in the winter, due to the constant usage; this is especially true, if your water heater is run on gas.
How can matter be more or less buoyant?
it can be more or less buoyant be having more or less mass.i.e. lead will sink in water because the mass is higher and wood will float because it is lighter. the more mass the less buoyant, less mass means more buoyant.
Is the influence of cool ocean currents on coastal temperatures more pronounced in summer or winter and why?
Because the water level rises at the summer temperature.
Why will be the buoyant force more if the volume of the object is more?
More volume means that the object displaces more water. The buoyant force is exactly equal to the weight of the displaced water. Or other liquid.
