If you get hay fever, you probably don’t need reminding when pollen levels are high. You can feel it. The scratchy throat on the morning commute. The streaming eyes halfway through a meeting. The sudden need to check whether you packed antihistamines before leaving the house.
Pollen levels shift quickly. They change with the weather, the season and where you are in the country. A warm, dry, breezy day in one region can mean something very different in another. That’s why we’ve created the Patient.info pollen map – to give you a clearer picture of what’s happening where you live.

Why local matters
Headlines often talk about “high pollen” across the UK, but hay fever isn’t that simple. Tree pollen tends to peak in early spring. Grass pollen is usually the main culprit in late spring and early summer. Weed pollen becomes more common later in the season. On top of that, rainfall, wind and temperature all play a part in how much pollen is actually in the air.
If you’re planning a run, a school sports day, a picnic or even just opening the windows, it helps to know what the levels are locally rather than nationally.
What you’ll see on the map
Tillbaka till innehållThe map shows current pollen levels across different parts of the UK, graded from low to very high. It’s designed to be quick to check and easy to understand. You can see:
What the level is in your area
How it compares to surrounding regions
Whether conditions are likely to be manageable or more challenging
It’s not about causing alarm. It’s about helping you plan.

Using pollen information in real life
Tillbaka till innehållFor some people, checking pollen levels becomes part of their daily routine during spring and summer – a bit like checking the weather. If levels are high or very high, you might choose to:
Take antihistaminer earlier in the day
Avoid drying clothes outside
Keep car windows closed on longer journeys
Shower and change after spending time outdoors
Time outdoor exercise for after rain, when pollen can be temporarily lower
Small adjustments can make a noticeable difference.
If symptoms are hard to control
Tillbaka till innehållMost hay fever can be managed with treatments from a pharmacy, such as antihistamines, steroid nasal sprays or eye drops. But if symptoms are persistent, affecting sleep, or triggering asthma, it’s worth speaking to a pharmacist or GP for advice.
Keeping an eye on pollen levels won’t prevent hay fever, but it can help you understand patterns and feel a bit more prepared.

Frequently asked questions
Tillbaka till innehållWhat are pollen levels?
Pollen levels refer to the amount of pollen in the air at a given time. They are usually graded from low to very high. The higher the level, the more likely people with hay fever are to develop symptoms such as sneezing, itchy eyes and a blocked or runny nose.
Why do pollen levels vary across the UK?
Pollen levels are influenced by local plants, weather conditions and geography. Rain can temporarily lower pollen levels by washing pollen out of the air. Warm, dry and windy conditions tend to increase the spread of pollen.
When is hay fever season?
Hay fever season in the UK usually runs from March to September. However, the exact timing depends on which type of pollen you are sensitive to.
How can checking local pollen levels help?
Checking local pollen levels can help you plan your day. It can also help you understand patterns in your symptoms. For example, you may notice that your hay fever worsens on warm, windy days when pollen is more easily spread.
Can pollen levels trigger asthma?
Yes. For some people, high pollen levels can worsen asthma symptoms. This is sometimes called “hay fever asthma” or allergic asthma.
If you have asthma and notice that your symptoms worsen during high pollen days, it’s important to ensure your inhalers are used as prescribed and to seek medical advice if control is poor.

When is hay fever season in the UK - and how can you avoid the symptoms?
For one in five of us, the arrival of spring or summer after the long, cold winter months is a mixed blessing - and a microscopic powder is to blame. Hay fever is cause by an allergy to pollen produced by grass (hence the 'hay' in hay fever) or sometimes trees or weeds.

When should I start taking hay fever tablets?
Is it too early to start taking hay fever tablets? Experts reveal that these work best when started ahead of hay fever season - before the symptoms irritate 1 in 5 of us in spring and summer. Hay fever tablets are a popular fast-acting treatment option for immediate relief. We explore how they can also be used as a preventative measure before the weather warms, the flowers bloom, and hay fever season kicks in.
