If your work doesn't compel you to a uniformed outfit:

Wear T-shirts and soft material clothing that allow free flow of air into your body.

Shorts are appropriate during this period, same as sandals.

Backpack is an essential apparel to carry your effects and water bottle.

Drink a lot of water to stay hydrated.

If you work outdoor, sunglasses are necessary.

Consider wearing hat to protect your scalp.

This period, do away with tight denim if you can.

Finally, enjoy the African sun.

Yours manly,
Manspace.
