Port Glasgow sits in Inverclyde and takes its pollen pattern from the Strathclyde forecast region. Around 14,200 people live here. Hay fever sufferers should track all three pollen types from March through August.
Tree pollen here is dominated by birch, alder and oak, with grass led by ryegrass and cocksfoot and weeds by nettle.
Tree pollen typically peaks in late April. Grass counts are highest from late June. Wet weather can suppress counts, but breaks of fine weather see sharp birch and grass peaks.
