Pollen Station:. Reference: Adams-Groom et al. Below is a generalised pollen calendar to show when the main allergenic plants are in flower.
The timing will differ from south to north and also west to east and with height above sea level. The exact timing and severity of the pollen seasons will differ from year to year depending on the weather and on biological factors.
Though it is impossible to completely avoid pollen there are lower pollen holiday destinations that vary depending on the time of year. Low tree pollen holiday destinations. Low grass pollen holiday destinations. Pollen Calendars by area. Regional Pollen Calendars Map of pollen forecast regions and main pollen monitoring station location, per region red dots. Each pollen calendar ranges from: Light Green - Earliest to latest pollen appearance, low risk Darker Green - Range onset to end 2.

The common silver birch is a single-stemmed, deciduous tree up to about 25 metres tall, with distinctive silvery bark. Birch pollen is highly allergenic and is a significant cause of asthma and rhinoconjunctivitis. Pollination occurs from spring to early summer, peaking between April and May. The European ash is a broad, deciduous tree, growing up to 35 m in height. Ash trees are wind pollinated, with pollen travelling up to metres from the tree. They spread large amounts of pollen during the flowering season, which in the UK is from March to May, with the peak occurring in April.
The London plane tree is easily identified by its distinctive bark which peels in large flakes. It is commonly found in urban areas of the UK, planted along streets and in squares. Over half of the trees found in central London are of this species. London plane is wind pollinated and pollination peaks during May. Oaks are large deciduous trees with broadly spreading canopies, found throughout the UK both in rural areas and in urban or suburban parkland.
Flowering generally occurs in spring but may vary based on local temperatures and weather conditions, with pollination peaking around May. Oilseed rape is a common food crop in the UK, grown principally for oil production. Oilseed rape fields are easily recognisable by the bright yellow flowers which are characteristic of this species. It is partially wind pollinated, with peak pollen release occurring from May to June.
Pine is a coniferous tree growing up to 35m in height, with upward pointing branches and a narrow, tapering shape. The majority of species flower in spring and early summer in the UK, peaking around May.
While the pollen count is high, the individual pollen grains are relatively large, which can reduce sensitisation. Grass pollen is one of the most common causes of allergic rhinitis hayfever , and may also cause contact dermatitis in sensitised individuals. In the UK the grass pollen season runs from spring through to early autumn, with its peak in summer.
