Great pics though (yours) the "fog" is prolly sea salt that get´s carried when is very windy I guess, Lopes is on the open sea side of the island so it´s usually windier than other beaches in Ilha Grande. Four months ago when you posted this, was March/April which are rainy/windy months on the island. Best months to visit September through February, get´s very hot (38-40C) but I really love April-September, specially May-June-July when the island get´s less visitors. Cheers!
