I was the flying pilot and [the] First Officer was Pilot Monitoring; landing Runway 28L in SFO. Wind approximately 010/20 G30 kts. VFR conditions; cleared for a visual approach. At approximately 1000 FT on approach a 737 passed us on our right landing 28R. At approximately 30 - 50 FT above threshold the right wing started to come up. I responded with right aileron to counteract the roll. It took full right input to stop the rising right wing. The right wing finally started to lower and I neutralized the control and added back pressure as the aircraft was losing lift. The aircraft had a firm touchdown. I feel like the crosswind and the wake turbulence from the 737 contributed to the event. Although I was on or very close to approach speed; the aircraft was at too low an energy state to counteract the above forces. I felt minimal control authority the final 2-3 seconds of flight until touchdown.
A320 Captain reported a firm landing occurred following a wake turbulence encounter on short final at SFO with a B737 landing on the parallel runway.
