The UK Pollen Season, Month by Month
Pollen is not one season but three overlapping ones, which is why many people react at different times of year. Understanding the calendar helps you prepare before your trigger arrives.
| Pollen type | Typical UK season | Who it affects most |
|---|---|---|
| Tree pollen | Late March to mid-May | Early-season sufferers (birch, oak, plane) |
| Grass pollen | Mid-May to July | The majority of hay fever sufferers |
| Weed pollen | Late June to September | Late-season sufferers (nettle, dock, mugwort) |
Grass pollen is the most common trigger in the UK, affecting around 95% of hay fever sufferers. Counts are typically highest on warm, dry, breezy days and in the early morning and evening. Checking the Met Office pollen forecast for your region is the simplest way to plan ahead.
Why Air Filtration Helps
Pollen grains are small enough to stay suspended in the air and settle on bedding, carpets and soft furnishings, so symptoms often continue indoors long after you come inside. Reducing the amount of airborne pollen in the rooms where you spend the most time is one of the most practical, non-medical steps you can take.
A quality air purifier draws room air through a fine filter and returns it with far fewer particles. A MERV-13 filter captures around 93% of airborne particles, including pollen, dust and pet dander. Running one in the bedroom overnight means you are breathing cleaner air during the hours your body recovers, which many people find makes the biggest difference to morning symptoms. Filtration does not treat hay fever, but it lowers your exposure at home, and lower exposure means a lighter symptom load.
Start With the Bedroom
If you only tackle one room, make it the bedroom. You spend around a third of your life there, and overnight pollen exposure is a major reason people wake up congested and tired.
- Filter the air where you sleep - run a purifier sized for the room, ideally on a quiet overnight setting.
- Keep windows closed during high-pollen mornings and evenings, and ventilate at low-count times instead.
- Shower and change before bed to avoid carrying pollen onto your pillow.
- Wash bedding weekly at 60C and dry indoors during peak season to keep pollen off the sheets.
- Keep pets out of the bedroom if they have been outside, as fur carries pollen indoors.
Trusted, Independent and UK-Focused
Our guidance is written for British conditions and cross-checked against authoritative sources, so you can act on it with confidence.
- NHS-aligned advice - our symptom and self-care guidance follows established NHS recommendations.
- Met Office and DEFRA pollen data - our seasonal guidance reflects official UK pollen forecasting.
- No medical claims - we are clear that filtration reduces exposure and supports comfort; it is not a treatment or cure.
Prepare Before the Season Peaks
The best time to reduce your symptoms is before pollen counts climb, not after your eyes are already streaming. A few steps taken early make the difference between managing hay fever and being floored by it.
- Check the Met Office pollen forecast for your region and note your trigger's peak weeks.
- Set up local pollen and air-quality alerts so you know when to keep windows shut.
- Get bedroom air filtration in place before grass season begins in mid-May.
- Start any antihistamine routine early, following NHS or pharmacist advice.
Cleaner indoor air, a well-managed bedroom and early preparation give you the best chance of a comfortable spring and summer.
