Pollen is moderate in DT (Dorchester) today.

DT covers part of South West England and follows its regional pollen pattern closely.

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.
