We supply and produce the pollen forecast for the UK in conjunction with the Met Office.

Weekly pollen forecast and summary

 

Forecast to 3rd May: Pollen: Oak pollen peaking; Spores: Generally low.

Grass Pollen Count - Low

 

Grass pollen is now being released from a couple of early-season species (meadow foxtail & sweet vernal). Symptoms will occur on dry days above 16°C in those people sensitive to these types.

Tree Pollen Count - High

 Pollen forecast for trees with a high orange pollen count.

Oak pollen is the main allergen airborne now in many regions, with some birch and ash in the far north of England, Northern Ireland and Scotland. Plane tree pollen is present in London and other cities where these trees are planted.

Fungal Spore Levels - Moderate

Pollen forecast for spores with a moderate yellow pollen count.

An unexpected spike in penicillium/aspergillus at our Worcester monitoring station has continued since 16th April. Possibly this is due to the arrival of drier weather allowing spores to finally disperse after all the rain. It's unclear how long it will last or how widespread it is. Usually most spores are low during April, apart from Pleospora at moderate risk to those sensitized to this type.

Weed Pollen Count - Low

Pollen forecast for weeds with a low green pollen count.

Weed pollen species including plantain and dock are in flower but the risk will remain low.

Pollen forecasts are available on a regional basis to cover the whole of the UK including Northern Ireland and the Republic of Ireland. They can also be provided in detail for individual regions.

Daily pollen and spore forecasts are issued from mid-March to early October.

Daily pollen forecasts are featured in newspapers, on radio, on television and various web pages.

All the forecasts are based on information from the quality controlled data produced by the National Pollen Monitoring Network, combined with the information from weather forecasts, local vegetation and typography types and information about biological factors and the weather in the preseason period that influences the pollen count.
