Like the title says how are oceanic waves created? I am vaguely familiar with how temperature creates currants in the ocean, but is this what helps create ocean waves?

Ocean waves are mostly produced by the wind. Air moves due to things like convection just like in the water, with warmer air masses rising and cooler air falling. Air moving against the surface of the water results in friction that drags some water, piling it up and causing a greater surface for the wind to push against.
Over hundreds and even thousands of miles this builds up into powerful waves which we observe in the ocean.
