Pollen Count & Forecast for Oxford, Cherwell

Oxford’s spring (March-May) sees dominant Birch and Oak pollen, originating heavily from University Parks and Christ Church Meadow, leading to high urban concentrations; summer brings pervasive Grass pollen (May-July) from the Thames riverbanks and Cherwell valley floodplains.

The city’s bowl-like topography and river corridors can trap pollen, intensifying local exposure; late-season Mould spores (September-November) are elevated by damp leaf decomposition along the Oxford Canal and within wooded college grounds.
