All else being equal the lower the viscosity of a liquid the faster it will flow since viscosity is a measure of the resistance (friction) to flow. So, if water flows faster it can only do so because the viscosity dropped, which it would very, very slightly on a warmer day. There is no other reason.

I'm not sure if water will flow faster when hot. Water is a Newtonian liquid and doesn't exhibit shear stress thinning or thickening. The viscosity of water will stay the same and not change when you apply sheer stress to it. If the viscosity does change with temperature, I would say that it would decrease the viscosity only very very slightly. Only due to the molecules of H2O being further apart and reducing its cohesiveness or surface tension.

My guess would be that because the molecules are farther apart in warm water - that there is less friction betwen the molecules. Also due to their having more enegy in warmer water - that extra enegy would allow them to move more quickly.

warner water is slightly less viscos then cold water,therefore it SHOULD move faster.Taken to the exterme,as the temperture of the water gets colder, it will eventually turn to ice ,then it will not flow at all.

it flows faster when its warmer because the heat of the hot days

I believe it is because the molecules are moving faster.
