Does warm water rise or fall in cold weather?

I think it falls

Does it have to do with convection???????

The question makes no sense. "Weather" implies the atmosphere and water is a liquid, so water falls in the atmosphere regardless of if it is warm or cold. Can you provide some context to the question?

Above 4°C, water gets denser as it cools. This means that warmer water rises under these conditions. Below 4°C, water becomes actually becomes less dense as it cools. Under those conditions warm water will fall as you guessed.

Are you reading "weather" as 'water'?

The situation I assumed he was talking about was you have some water outdoors like a lake or something, and the water is at a temperature close to the air, but it isn't completely uniform. It's the only way it makes sense. I know they sometimes give ocean temperatures in weather reports, so maybe the question is actually legitimate.
