A: There were northerly winds over North Atlantic in the months before the RMS Titanic left port. These winds likely played a role in pushing icebergs farther south than normal and into the Titanic?s path. When the Titanic left port in Queenstown, Ireland, on Thursday, April 11, 1912, it sailed under brisk winds from the north-northwest at 15-20 knots and a temperature of about 50 degrees.
