This is the satellite image of sea surface temperature two days prior to RU 15 being launched. The temperature is lower near the coast, and gets warmer as you move out to sea. The temperature seems constant, at about 18 degrees celsius.
This is the satellite image of sea surface temperature October 25th, about a week into RU-15's launch. The temperature difference between the Estuaries and the shelf is larger than on the 17th. But the mean temperature is still around 18 degrees Celsius.
