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.

The 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.

For 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.

Most 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.

What 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.
