Why no big waves in the oceans closer to the equator?

The absence of big waves near the equator is primarily due to the relatively calm wind patterns in this region, known as the Doldrums. These areas experience light and variable winds, which do not generate the strong, sustained energy needed to create large waves. Additionally, the warm waters near the equator can lead to less atmospheric instability, further reducing wave height. In contrast, higher latitudes often experience stronger winds and storm systems that produce larger waves.
