Wimbledon's Green Oasis: Beating London's Record Heat

Despite London enduring a record-breaking heat wave last week, with much of the city's grass turning brown, the famed courts of Wimbledon remain vibrantly green. This feat is achieved through meticulous planning and advanced horticultural practices by Neil Stubley, the All England Club's head of courts and horticulture, and his team.

Stubley and his 31 groundskeepers constantly monitor weather forecasts, utilizing approximately 25 weather applications. Their success is attributed to decades of research into drought-tolerant and hard-wearing grass species, with perennial ryegrass being used on all tournament courts since 2001. Probes on key courts measure soil moisture, crucial for maintaining court surface integrity.

The preparations have been essential as Britain recorded its warmest June ever, with high overnight temperatures also exacerbating the heat. Although temperatures at Wimbledon this week have been below 26 C (79 F), hotter weather is forecast, with no rain anticipated during the tournament. This follows a drier-than-average spring in London.

Organizers also focus on water conservation, exploring options like recapturing and reusing water and potentially using boreholes. Wimbledon is unique among Grand Slams for being played on a natural grass surface, unlike the hard courts of the Australian and U.S. Opens or the clay of the French Open. The Sports Turf Research Institute independently verifies court conditions, providing data on moisture, hardness, and grass wear.

Beyond heat, player actions like sliding on court can also damage the grass. Groundskeepers use precise data to manage each court's microclimate, adjusting water levels to ensure consistent playing conditions. This detailed approach ensures Wimbledon maintains its iconic green spectacle despite environmental challenges.
