Early Hay Fever Season Alert: What to Expect in 2026

Millions of people across England are bracing for a potentially early start to hay fever season, with warnings issued by the UK Health Security Agency (UKHSA). Research suggests that warmer temperatures are causing pollen and other allergens to be released sooner and for longer durations, potentially impacting allergy sufferers as early as January or February.

What is Driving the Early Start?

Traditionally, hay fever season in the UK runs from the finish of March to September. However, climate change is altering this pattern. Rising temperatures are prompting earlier pollen release, meaning symptoms could begin months ahead of schedule. The UKHSA alert, posted on X (formerly Twitter) on March 2, 2026, highlights that some types of pollen and allergens may be released earlier in the year and for longer periods as the climate warms.

Who is Affected?

Approximately 10 to 18 million people in the UK suffer from hay fever, representing 20% to 25% of the population according to the Met Office. This condition, an allergic reaction to pollen, is becoming increasingly prevalent.

Understanding the Pollen Season

The UK pollen season is typically divided into three phases:

• Tree Pollen (March to May): The first phase, characterized by the release of tree pollen.
• Grass Pollen (Mid-May to July): The second phase, dominated by grass pollen, is often the most impactful for hay fever sufferers.
• Weed Pollen (Late June to September): The final phase, involving weed pollen.

The current alert specifically points to tree pollen as a key driver of the early season, with warmer temperatures amplifying symptoms.

How to Manage Hay Fever Symptoms

Whereas there is no cure for hay fever, several preventative measures can help reduce symptoms:

• Keep Windows and Doors Closed: Especially between 10 am and 3 pm, when pollen counts are typically highest.
• Check the Pollen Forecast: Stay informed about daily pollen levels.
• Apply Vaseline: A small amount of Vaseline around the nostrils can trap pollen.
• Wear Sunglasses: Wraparound sunglasses can prevent pollen from entering the eyes.
• Shower and Change Clothes: After spending time outdoors, shower and change clothes to remove pollen.
• Stay Indoors: When pollen counts are high, consider staying indoors or planning indoor activities.
• Dust and Vacuum Regularly: Employ a damp cloth for dusting and vacuum frequently to remove pollen from your home.

Looking Ahead

As the climate continues to change, the trend of earlier and longer hay fever seasons is likely to continue. Staying informed about pollen forecasts and taking preventative measures will be crucial for managing symptoms and enjoying the warmer months.
