This is a typical symptom that it might be just a little low on refrigerant.
Check your pressures against the chart below. Make sure you take your readings with:
Engine @ 2000 rpm
A/C in coldest setting
Fan at maximum speed
Both windows down
Thermometer in center air vent
When adding refrigerant, pay attention to both pressures, otherwise you might end up with the high side sky-high trying to get the low side to the chart's value.
