Pollen is low in NR (Norwich) today.

NR covers part of East of England and follows its regional pollen pattern closely.

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.
