it because of the Land and Sea Breeze..
sea breeze comes from the sea and land breeze comes from the land.

Answer 2

Because water changes temperature much slower than air. It takes the whole day to warm up, so by night it's warm, then takes the whole night to cool down. This is what causes sea breezes. The air over the land changes temperature faster than that over the ocean, during the day the air over land is warmer and thus less dense than that over the sea, the denser air diffuses into the less dence air creating a breeze, the opposite happent at night.

Answer 3

It's not
the air is warmer during the day in sun light and that makes the water feel colder and the air is cooler at night without the sun so that makes the water feel warm to the touch.

Answer 4

water kinda has a reverse affect to weather. see when the air is warmer the water tends to be a bit cooler and vice versa, i cant remember why but i learned about it in school.

Answer 5

air changes its temperature faster than water, so during the day the air above the water heats up faster than the water, and the opposite at night, so the sea water are colder than the air during the day and hotter during the night, our body, that is part in water and part in th air feels the difference in temperatures and not the absolute temperature of each.

Answer 6

I don't think it is but it feels warmer at night compared to the ambient air temperature.

Answer 7

water has very high specific heat of capacity so it absorbs a lot of heat in day and still is cooler and in night it gives out heat but temperature fall very slowly

Answer 8

I think its not. Try to bring a thermometer to measure the actual temp.
