Where is Senegal?

This map gives an idea about where I will be located on the continent of Africa. From preliminary research, it looks like the climate is tropical, hot, humid, and rainy during the month of July. I've been advised to bring mosquito netting, bug spray, clothes that cover most of me, and a light rain jacket. ??? I promise to report back from Senegal with what works as far as attire.
