The reason was that the Europeans were vulnerable to tropical diseases. By the late 19thC when knowledge about treating these diseases became available then tropical regions became populated.
You will note that the temperate parts of Africa (the southern regions) were populated by the 18th C. The British/Dutch were in South Africa and the Portuguese had a presence in Angola and Mozambique.
