Southampton Pollen Count Forecast

Data from Open-Meteo / CAMS European pollen model • Last checked: 23:46 on Wednesday 28 October 2026

⚠ A note on accuracy: this page uses a free automated European pollen model (CAMS), which is known to sometimes read lower than reality for UK grass pollen compared with the Met Office's own UK-calibrated forecast. If today's figures below look low but your symptoms say otherwise, check the Met Office's official regional pollen forecast for a second opinion.

Understanding Your Symptoms

Use the pollen calendar to identify which pollen types trigger your symptoms:

Symptoms in January–March are likely alder or hazel pollen. Symptoms in March–May suggest tree pollen, especially birch or oak. June and July are the peak of grass pollen season — the most common cause of hay fever in the UK. Late summer symptoms point to weed pollens such as mugwort, while autumn symptoms may indicate fungal spores.

Some people are allergic to more than one pollen type, and several types cross-react. Alder, hazel, hornbeam and birch share similar allergens — if you react to one, you are likely to react to the others.

Pollen Avoidance Tips

Outdoors

  • Avoid going out during peak pollen hours — for grass, that is 7–10am and 4–7pm.
  • Don't dry washing outside on high pollen days — it will collect pollen from the air.
  • Wear wrap-around sunglasses and a broad-brimmed hat.
  • Avoid high-pollen locations such as areas of uncut grass, woodland during tree pollen season, and inland lowland areas which tend to have higher grass pollen counts than coastal areas.
  • After being outside, shower and change clothes to remove pollen from hair and skin.

Indoors

  • Keep windows and doors closed during peak pollen hours.
  • For some respite indoors, close all windows, sit still, and after about 25 minutes most airborne pollen will have settled — you will then be breathing much cleaner air.
  • Cover beds and surfaces when not in use — pollen is heavy and settles quickly.
  • Brush or wash pets regularly — cats and dogs can carry significant amounts of pollen in their fur.

Driving

  • Keep car windows closed in high pollen conditions.
  • Service your car air filter regularly.
  • If possible, choose a car with a good pollen filter.

Treatment

Talk to your GP or pharmacist about antihistamines, nasal sprays and eye drops. Most symptoms can be well controlled with the right medication — ideally started a couple of weeks before your personal pollen season begins, rather than waiting for symptoms to appear. It is best to combine medication with avoidance measures.
