Britain is set for a mix bag of weather over the coming days with "heavy thundery downpours" predicted in some parts of the country.

With the weather so unpredictable at present most people will welcome being allowed inside pubs from Monday (May 17) even if summer is almost upon us.

The main issue arising over the coming days could in fact be the high levels of pollen that are predicted for certain areas of the UK bringing misery to those suffering from hayfever.

Most people will think high pollen levels and hay fever only effect people when it is hot and sunny but storms and downpours can also bring about the right conditions for pollen to increase

According to The Sun the wet weather over the coming days will "trigger a pollen bomb" which is when levels suddenly spike out of no where.

Over the next four days the highest pollen levels will be found in London, south-east England, south-west England and East of England.

In London high levels of pollen are expected on Wednesday, Thursday and Friday.

Around one in four people in the UK suffer with hay fever every year.

Hay fever is an allergic reaction to pollen, a fine, yellow, powdery substance that comes from plants which fertilise seeds. It typically comes into contact with your mouth, eyes, throat or nose.

According to The Sun from July 19, weather forecasters are predicting temperatures of 24C with no rain, and then in the following week seven days of temperatures at 25C.
