Weekly pollen forecast and summary


Forecast to 19th July:  Pollen: Grass pollen high, weed pollen moderate, sweet chestnut tree pollen moderate; Spores: High.

Grass Pollen Count - High

 Pollen forecast for grass with a high orange pollen count.

Grass pollen will continue at a high risk during any lengthy spells of warm, dry weather. The season is in the later stage but is lasting longer this year. This is due to cool temperatures reducing opportunities for the plants to exhaust their pollen stocks to the air

Tree Pollen Count - Moderate

 Pollen forecast for trees with a moderate yellow pollen count.

Sweet Chestnut currently airborne at moderate risk during warm, dry weather.

Fungal Spore Levels - High

Pollen forecast for spores with a high orange pollen count.

When the weather improves, Cladosporium & Alternaria will be at a high risk. Didymella, Leptosphaeria and allies will be high during warm and very humid conditions.

Weed Pollen Count - Moderate

Pollen forecast for weeds with a moderate yellow pollen count.

Nettle pollen at a moderate risk during dry weather, along with a few other weed pollen types.
