Abstract: The lightning activities in Brass, Bonny, Opobo and the Calabar axis are very high. The mechanism for the formation of thunderstorm is strong convective processes. The sea breeze, the different temperature and the humidity changes may lead to such processes, therefore the lightning activities (Keraunic level) in these areas are high. The study is aimed at establishing the average ground flash density in the area. This was done by taken records of the lightning days for a period of 2 years in three different sites. This figure was compared to some data taken from meteorological stations. The cloud to ground flashes recorded within the working period was much fewer compared to the total flashes. When the ground to clouds was taken as 5:1, the number of days was between 120-150 days year^-1 that is the ground flash density was 12-16 flashes/km²/year. The need to know the lightning activities cannot be over emphasized when considering protection of electrical, electronic and telecommunication designs and constructions. This research was done to sensitize the government, companies operating in the area and line designers to provide better lightning detectors for more accurate figures in the area.
