Probably a low charge, but you'll want to get a set of gauges to figure that out. It could also be too much charge combined with high ambient temps, so don't just go putting in a can.
If you find that you've had a leak, I highly suggest that you follow the advice in the General AC Troubleshooting and Repair at the top of this forum (for the summer at least). If you simply put a can in, then don't be surprised if you have to do it again before the summer is out. Stop leaks can lock up your compressor if the leak is too large.
