Pollen Count & Forecast for Carlisle

Carlisle experiences significant spring Birch pollen (late March-April) from Bitts Park and urban tree-lined avenues; Oak pollen (late April-May) from mature trees in Rickerby Park and wider green spaces follows. Summer brings prevalent Grass pollen (May-July) originating from extensive River Eden riverbank meadows and Carlisle’s surrounding agricultural land.

Carlisle’s low-lying position within the Eden Valley often exacerbates pollen concentration, particularly during calm, warm periods; prevailing westerly winds from the Solway Firth also transport regional pollen. Late season and winter months present elevated Mould spore levels (September-February), intensified by damp conditions, leaf decomposition in urban parks, and riverine humidity.
