It was the latest in a long series of acts of civil disobedience that they have staged to highlight the need to tackle the climate crisis.
One of the protestors ran onto the court where American Madison Keys and Romanian Sorana Cirstea were in action, throwing white liquid onto the surface.
Two other protesters tried to glue themselves to the stands.
Other protestors disrupted play on another court where a men’s doubles match was taking place.
Police removed the activists and play resumed after the mess was cleared up, with Keys completing a 6-2, 6-1 victory.
“With today’s act of civil disobedience, we want to remind everyone that last year 62,000 people died from the heat in Europe,” UG said in a statement.
“This is just one of the many effects of the climate and ecological crisis.
“Profound change in our system is essential to safeguard our territory and its citizens.
“Non-violent resistance is an alternative to political apathy.”
