His main opponent Jaroslaw Kaczynski, an ex-prime minister who now leads the conservative Law and Justice party, was second with 36.46% of the vote.
As of 15:00 Moscow time (11:00 GMT) on Sunday, 30.6% voted in Polish capital of Warsaw, 27.92% - in Gdansk, 28.45% - Wroclaw.
The turnout forecast for the runoff is about 54%.
Preliminary voting results and exit polls are set to be announced at 22:00 Moscow time (18:00 GMT), soon after the last polling stations close.
Polish Central Election Committee is set to sum the results of the election on Monday, July 5.
