Late spring and early summer bring grass pollen. This often happens from May into July. Many grasses around fields, parks, and roadsides release it. Ryegrass is common in Ireland. On dry, breezy days, grass pollen can spread far and wide.

Summer is also a time for weed pollen. It often appears from June through August. Plants like nettle, plantain, and dock can release pollen. These plants grow in rough ground, gardens, and along paths. Their pollen is usually strongest in warm, still weather.

Autumn brings much less pollen in Dalkey. By September and October, most tree and grass pollen has faded. Some late weeds may still release small amounts. The air feels cleaner as the year cools. Winter is usually the quietest time for pollen.
