Pollen is low in Bristol today.

Hayfever sufferers in Bristol should track all three pollen types from March through August.

Tree pollen here is dominated by oak, ash and hornbeam, 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. Mild winters bring tree pollen forward; coastal breezes can keep the grass count down on the worst days.
