The UK is set for a sizzling 10-day heatwave, with highs of 33°C in some parts of the country.
However, reports of very high levels of pollen and UV, means it could be bad news for hayfever sufferers.
This is due to dry spells and lights winds building up during the spring period.
Speaking to Sky News, a Met Office spokesperson said: "As we go to the weekend, particularly Saturday, we will start to see very high levels across the whole of England.
"It's a combination of two factors.
"Towards the end of spring we had perfect conditions for pollen growth - warm and wet - and since then we've had pretty cool conditions for plants to shed and release pollen.
"Spells of dry weather, fairly light winds if any winds, that allows the pollen levels to build up.
"We're also right in the middle of the grass pollen season."
What are the symptoms of hay fever?
The symptoms of hay fever, according to the NHS:
- sneezing and coughing
- a runny or blocked nose
- itchy, red or watery eyes
- itchy throat, mouth, nose and ears
- loss of smell
- pain around your temples and forehead
- feeling tired
If you have asthma, you might also have a tight feeling in your chest, be short of breath or wheeze and cough.
How can I treat it?
Tips on how to treat hay fever, according to the NHS:
- put Vaseline around your nostrils to trap pollen
- wear wraparound sunglasses to stop pollen getting into your eyes
- shower and change your clothes after you've been outside to wash pollen off
- stay indoors whenever possible
- keep windows and doors shut as much as possible
- vacuum regularly and dust with a damp cloth
- buy a pollen filter for the air vents in your car and a vacuum cleaner with a special HEPA filter
You can also buy eye drops and antihistamines from most pharmacies to relieve your symptoms.
In some cases your GP might prescribe steroids.
If steroids and other hay fever treatments don't work, your GP may refer you for immunotherapy.
This means you'll be given small amounts of pollen, as an injection or tablet, to slowly build up your immunity to it.
This kind of treatment usually starts in the winter about three months before the hay fever season begins.
The Met Office monitors the pollen count on a daily basis, using weather data. You can check it here .
