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.
