Not being absorbed by real world water, visible is not only not capable because of its tiny scale of moving the whole molecule of water into vibration which is what it takes to heat water, but it isn't even able to be absorbed by the electrons of the water molecules as the electrons of the molecules of air absorb it, so water doesn't reflect / scatter visible light on the electrons of molecule level as does air, but gives up and passes it along, and so, visible is transmitted through, also, unchanged, but much delayed.

Also you focused on re-radiating meaning emitting long - wave spectrum - which possible, but I was thinking more about emitting the same wavelength, as mentioned in this quote: «However, aerosols (which often contain water and if so can absorb red wavelengths) are usually larger than visible wavelengths and therefore absorb and reflect all wavelengths of light equally (this is not technically scattering, although it is often called that; it technically involves absorption and re-radiation, or reflection).»
