The air quality on the Isle of Wight is often much cleaner than other locations in the South of the UK, and this all due to the winds frequently blowing from the Atlantic Ocean and making their way up the English Channel. However we do see occasional spells of poor air quality, usually due to stagnant air sitting over the UK from a large anticyclone (high pressure area) or sometimes from Central,  Southern and occasionally Eastern Europe when the winds blow in from the East or Southeast. 

We rate the air as GOOD, MODERATE, UNHEALTHY FOR SENSITIVE GROUPS, UNHEALTHY, VERY UNHEALTHY  and HAZARDOUS, although we rarely reach “unhealthy” levels here on the island.

We believe that a Pollen Forecast is an essential part of any forecasting system as around 20% of islanders suffer with Pollen Allergies to some degree! However, our Forecast is rather unique as it covers 6 different areas (5 coastal locations and 1 “inland” area), often allowing you to find an area on the island for some allergy relief.










Pollen levels vary throughout the season, this can be influenced by many things, including wind strength and direction, temperature, humidity, whether it is cloudy or sunny as well as the time of year.

On our small island the Pollen season usually starts sometime in mid/late March although during a mild winter it can start as early as late February.

MARCH often starts off on a rather positive note for allergy sufferers with only a handful of trees types producing pollen locally, although as the month goes on we start to see increasingly large amounts of tree pollen along with the beginnings of flower pollen from various wild plants and weeds.

APRIL is another tree pollen month, in fact can be quite a bad time for pollen allergy sufferers, especially towards the end of the month. We also see a moderate amount of weed and wild flower pollen locally. Rapeseed often starts to show itself early in the month too and this can reach high levels by the end of the month.

MAY is a rather mixed month for pollen with both tree pollen (albeit starting to wane) along with increasing amounts of grass pollen and locally wild flower pollen. Rapeseed is often out until at least mid month in most years.

JUNE still sees moderate amounts of tree pollen to start the month although falling rather quickly as the month goes on but grass pollen can be extremely high, this includes crops such as wheat, oats etc. We also start to see weed pollen coming back in to play, with plants such as Nettle producing significant amounts. Wild flowers are still in full swing in more rural areas and produce varying amounts of pollen.

JULY sees tree pollen levels drop significantly, but grass pollen is still high. Weed pollen often soars in July along with various wildflowers in rural areas. 

AUGUST usually sees grass pollen dramatically dropping off, but weed pollen is now reaching its maximum, especially around the middle of the month.

SEPTEMBER is another month of weed pollen, possibly at its height early in the month if the summer has been cold and wet.

OCTOBER is a much less problematic month, with weed pollen dropping off significantly as the month goes on, although in some years the weed pollen may linger on until the end of the month, but this is only likely if the summer has been very poor along with the start of autumn being warm and dry.

This Pollen Calendar was written for the Isle of Wight only. Other areas in Southern England often see Pollen peaks at slightly different times throughout the season. The information is based upon a mixture of national statistics, visual observations and photographic evidence.
