Harwich sits in Essex and takes its pollen pattern from the East of England forecast region. Around 20,700 people live here. Hay fever sufferers should track all three pollen types from March through August.
Tree pollen here is dominated by oak, ash and silver birch, with grass led by ryegrass and timothy and weeds by nettle and plantain.
Tree pollen typically peaks in April. Grass counts are highest from June. The dry, flat farmland tends to give grass pollen a long run from late May through July.
