Voters were already queuing at voting stations when the polls reopened at 8 a.m. on Thursday.
There are some 50 million eligible voters including 24 million women voters.
However, turnout was lower than an earlier parliamentary vote.
There are 13 candidates in the race. The Muslim Brotherhood said its candidate, Mohamed Mursi, was ahead after the first of two days of voting but he is not expected to get more than 50 percent of the vote.
If no candidate gets more than 50 percent of the vote a second round between the top two candidates will be held on June 16 and 17.
