The Pacific Ocean, alone, has a greater surface area than all the land masses of Earth, combined. Water, especially a large deep mass of water like the Pacific, can hold a lot of heat energy. And we don't know what is happening with the heat transfer and storage cycle; we don't even understand the full operation of heat exchange between ocean and the rest of the planet. Thermocline is "about" 800 meters of water depth (that's a HUGE heat sink): https://oceanservice.noaa.gov/facts/thermocline.html https://oceanservice.noaa.gov/facts/thermocline.html
