Rhyl sits in Denbighshire and takes its pollen pattern from the Wales forecast region. Around 25,900 people live here. Hay fever sufferers should track all three pollen types from March through August.
Tree pollen here is dominated by oak, birch and alder, with grass led by ryegrass and cocksfoot and weeds by nettle and dock.
Tree pollen typically peaks in April. Grass counts are highest from June. Mountain rain can clear the air quickly but valley pockets see persistent grass counts in June.
