Andrew Carney, 25, was driving at more than twice the speed limit before he lost control of his car and hit Jacqueline Lyon's BMW on the wrong side of the road.
Carney had climbed into the car with his friend after a row with his girlfriend before speeding in the atrocious weather. He overtook a number of shocked witnesses on the road, a court heard.
Carney, from Aberdeen, pled guilty to causing the death of Mrs Lyon, 47, by dangerous driving on August 27, 2012, on the Beach Esplanade in Aberdeen. He also admitted driving without a license or insurance.
Richard Freeman, defending, said Carney had shown "genuine remorse".
At the High Court in Glasgow yesterday judge Lord Turnbull sentenced Carney to seven years and two months and banned him from driving for 10 years.
Lord Turnbull said: "Should any road user choose to drive in a reckless manner, they must take responsibility for the consequences of that decision."
