Why would Columbus have taken the slightly northward and southward routes?

Columbus may have taken slightly northward and southward routes during his voyages to optimize favorable winds and ocean currents, which were crucial for sailing efficiency. Additionally, exploring these variations allowed him to navigate around potential obstacles, such as land masses and adverse weather conditions. This flexibility in routing also increased his chances of discovering new territories and trade routes. Ultimately, these strategic navigational choices reflect his adaptability and determination to achieve his goals.
