Spring is a busy pollen time in Clevedon. Oak, ash, and plane trees add more pollen as the weather warms. Grass pollen starts to appear by late spring too. This makes the air fuller with pollen from April into June.

Summer brings the strongest grass pollen season. Many fields, parks, and gardens in and around Clevedon release grass pollen from May through July. Dock and nettle plants can also add some pollen during warm weeks. Dry, breezy days spread it farther.

By late summer and autumn, pollen levels often change. Weed plants such as mugwort and plantain can release pollen from July into September. Tree pollen is mostly gone by then. Cooler weather and rain usually help clear the air.
