I know it is not raining now but over the last several weeks there has been a lot of rain in the mountains and it takes time for that extra water to make its way down the river system. Normally the amount of water exiting the Negril River does not have that big a impact on the area beaches but when you have a abnormal amount of run off this happens not only in Negril but any coastal area anywhere in the world. The normal flow only has light stain color but extra run off from heavy rains picks up more debris and gets a darker color.
