as i remember it from my sailor experience 15 or so years ago there are only two seasons there. it is a tropical climate, so the rainy season and the dry season. at Accra it rains cats and dogs from april to november with squalls usually afternoon.
dry season is usually for your biggest ever kite if at all.
not good for kiting at all
good thing the people was very friendly then. there is no some crazy tribal or religious hatred.
