Around Helensburgh Rhu, Scots pine and birch are the dominant species behind local tree pollen, with counts higher near parks than in the centre. Surrounding Argyll and Bute farmland contributes substantial grass and tree pollen, moving into town when winds blow from the east. It's a pattern shared by plenty of similarly sized towns nearby, shaped more by geography than anything unusual locally.

Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

Are pollen levels in Helensburgh Rhu based on measurements or forecasts?
