A steady downpour at lunch meant the match could not resume at the scheduled time in the second session.
Post-lunch play has now been extended to make up for the lost time.
Sri Lanka were 108-3 when rain stopped play to gain an overall lead of 247 with seven wickets in hand.
The hosts had scored 421 in their first innings before bowling out South Africa for 282.
South Africa are 1-0 up in the series after winning the opener in Galle by 153 runs.
