Pollen grains from grasses (Family Poaceae) are the most common aeroallergen in Ireland, affecting approximately 95% of hay fever sufferers.  While tree pollen tends to cause hay fever in the early spring months, grass pollen is the main cause of hay fever in the earlier summer months.

Low Count
Pollen is classed as a low count when there are less than 30 grains/cubic meter.  At this level, the chance of symptoms developing are at a minimum.

Moderate Count
When there are 30-50 grains/cubic meter, the pollen count is classed as a moderate count.  Minor symptoms may occur at this level, meaning sufferers should at least take preventative medicines before going outside, especially if they have underlying conditions such as asthma.

High Count
When there are between 50-150 grains/cubic meter of air, the pollen count is considered as a high count.  The majority of hay fever sufferers will almost certainly show symptoms including swelling around the eyes and excessive mucus causing a runny nose.
