In brief: Grass

Fall weed pollenation typically concludes by the end of sept however, late rains can result in a second wave of grass pollenation.
Rains and warm weather can also result in high mold in the air. Go to pollen.Com for local pollen counts in your area.

In brief: Weeds

Weeds tend to be a fall allergen.
...So weeds could also be the problem. Grasses and weeds are similar but different and definitely pollinate at different times.
