when hot take a dip
The people in this photograph live along the coast close to the sea. I took this photograph at Kivukoni channel in the city of Dar es Salaam around midday when the sun was hot. At such a time many of the coastal inhabitants saunter and lazy about along the beach to get a cool breeze from the ocean. Here, they showcase what is one of their best recreational activities: swimming. Guess what economic activity these people would engage in.
I imagine they are fishermen, and probably use water as a means of transport. Your explanation of the heat at midday has made me understand why fishing is done too early in the wee hours of the morning? Or am I making assumptions? How much earlier do they need to begin travelling in the vessels like the one in the background if they have to wait at the channel, and are they charged to use them?
ReplyDeleteMy simple understanding of physics is that at night all the way till morning the sea water is warmer at the surface and cooler deeper. Thus, fish swim on the surface to follow the warmer current; while, when the sun is hot during the day, the warm current run deep. The fish then take a dip. Do not take my explanation too serious, confirm this with the fishermen themselves (for your information, I am not a physics teacher; I am a teacher of English!).
