The Met Office has issued a warning to people out and about in Bristol today due to the high levels of ultraviolet radiation hitting the city.
The sunny weather means the exposure to the radiation is 8 out of 11 on the exposure scale meaning it is relatively very high.
As a result the weather experts are urging people to avoid spending too long in the sun between 11am and 3pm today and say wearing a shirt, sunscreen and a hat as essential.
Bristol is forecast to have a UV index of at least 8 everyday this week during the middle of the day due to the heatwave that has hit the country.
UV radiation from the sun can have both positive and negative effects on human health.
A small amount of UV radiation is essential in the production of vitamin D, however too much exposure to the sun can have serious effects on your skin and eyes, according to the Met Office website.
It reads: "It is important not to be caught out by the sun so use our forecast, wear lightweight, light-coloured clothing, spend time in the shade and use a high factor sun cream with good UVA protection to protect yourself.
"Don't forget that UV rays from winter sun can actually be more damaging in alpine regions because you absorb both the direct UV rays from the sun and the diffuse UV rays reflected back from snow cover."
It comes as forecasters are predicting an absolutely scorching week in Bristol with temperatures reaching at least of the week.
Monday's forecast is sunshine throughout the day with temperatures reaching their peak between 3pm and 7pm.
Tuesday will be another blistering day with sunshine throughout and the max temperature hitting us at around 4pm.
Wednesday will again be sunny all day, according to current Met Office predictions with highs of 25C from around 4pm to 7pm.
Again temperatures will pick up to an estimated 27C on Thursday with more uninterrupted sun and the peak temperature reaching us at 4pm.
