The water in the ocean holds heat and moves it around the world. In the Pacific Ocean, the water moves clockwise and the warm air moves north up the coast. The Atlantic current moves from the north to the south, bringing the cooler northern air along the coast. The Atlantic coasts on the east are about 20 degrees cooler than the Pacific coasts on the west. Plus, water holds heat much longer than land and the Pacific Ocean is larger than the Atlantic, so it's heat would last longer than the Atlantic Ocean's heat.
Mountains also affect the temperature. Large amounts of clouds are usually gathered near mountains. During the summer time, warm clouds and rain heats up the mountain. This heat is used up during the winter time. The east coast does not have nearly the same elevations as west coast, therefore the precipitation is usually colder.

As a veteran of one east to west crossing via the trade winds, the best west to east routes are to the north, US - Bermuda - Azores - Europe. You have the benefit of the westerly winds and the Atlantic high. July is late to leave for a west to east crossing, the risk of hurricanes is increasing.

Best of Sailing!
Humans pollute the oceans along with garbage and all that bad stuff.

A deep sea port is a port that provides for the staging and anchoring or docking of boats, ships, and other marine vessels often for the purpose of loading or unloading products or goods. The difference between deep sea ports and regular ports is that a deep sea port has a longer depth from surface to sea bottom.
