Health experts are advising people not to watch the big match indoors because of increasing Covid infection rates amid the spread of the Delta variant.
But experts are concerned large groups will gather around screens indoors due to the heavy rain and thunderstorms predicted across England this weekend.
Public Health England's medical director, Yvonne Doyle, told The Sun: “Many of us will be joining friends and family to watch England in the Euros on Saturday night.
“But please follow the guidelines in place to reduce the risk and enjoy the match safely, watching the game outside will always be safer than gathering indoors.”
Heavy thunderstorms and showers are forecast for the weekend in the capital, although it is forecasted sunshine will be back later this month.
Met Office forecaster Alex Deakin said: “If you are looking for warm, sunny skies make the most of the short term because we are going to see a shift in weather patterns are we go through the weekend with the potential for heavy, thundery downpours.”
It comes as the coronavirus reproduction number, known as the R value, in England has dropped slightly.
R represents the average number of people each Covid positive person goes on to infect.
Now it is between 1.1 and 1.3, according to the latest Government figures.
In comparison, it was between 1.2 and 1.4 last week.
When the figure is above 1, an outbreak can grow exponentially but when it is below 1, it means the epidemic is shrinking.
