Swan Upping Returns to Surrey: A Royal Census on the Thames
Medieval Tradition Draws Crowds to Sunbury and Beyond
This July, the historic tradition of swan upping has returned to Surrey’s waterways, transforming Sunbury Lock and surrounding areas into a spectacle of natural heritage conservation. The five-day event, taking place during the third week of July, sees six traditional rowing skiffs journey through familiar local landmarks including Shepperton Lock and Penton Hook Lock before concluding 79 miles downstream at Abingdon Bridge in Oxfordshire.
For locals and visitors alike, the sight of uniformed teams in distinctive scarlet rowing along the Thames represents far more than a quaint riverside activity. This royal census, dating back centuries, reflects Surrey’s deep connection to environmental stewardship and wildlife protection. Colin Thomas, an Epsom-born resident now living in Australia, made the medieval tradition a centrepiece of his recent visit home, describing it as ‘fantastic to see vital wildlife being protected like this.’
The event has become increasingly important to the community as awareness grows about river conservation. Schools from across the region bring children to witness the skilled teams at work, creating educational opportunities that connect younger generations to local natural heritage. For many Surrey residents, swan upping represents the kind of authentic, community-focused activity that defines life along the Thames corridor.
Local Wildlife Teams Count Growing Cygnet Population
Behind the pageantry lies serious conservation work. The King’s Swan Marker, David Barber, now on his 34th annual swan upping, leads teams through detailed examination of adult birds and cygnets for injury, disease, and overall health. Every young swan is ringed during the process, allowing researchers to track movements and population trends across years.
The results offer encouraging news for Surrey’s river ecosystem. After recording 86 cygnets in 2024, the count rose to 115 in 2025—a significant increase that Barber describes as ‘very positive.’ Organisers are targeting similar growth this year, despite ongoing challenges including winter bird flu outbreaks.
Cygnets face numerous threats during their early months, from predators like birds of prey and foxes to pollution and disease in the river itself. Local conservation groups working alongside the official teams emphasise that protecting these birds requires community awareness and participation. Barber highlights the dual importance of conservation work and public education: ‘We have a lot of school children who come along and they absolutely love it.’ This engagement builds grassroots support for Thames river protection initiatives that benefit the entire local environment. For Surrey residents, the rising cygnet numbers represent tangible proof that community-led conservation efforts are delivering real results.
What Locals Should Know and How to Get Involved
Swan upping takes place annually during the third week of July, making it an easily accessible community event for families and nature enthusiasts throughout Surrey. Watching the skiffs pass through Sunbury Lock, Shepperton Lock, and Penton Hook Lock costs nothing and offers genuine educational value. Whether you’re witnessing the colourful uniforms and skilled rowing or learning about ring-marking techniques, the event provides a window into practical conservation.
For local residents interested in broader Thames protection, the swan upping season offers a natural entry point into river conservation advocacy. Community groups and local environmental organisations often coordinate awareness campaigns during this period, highlighting water quality issues, pollution, and habitat preservation alongside the swan census.
Parents looking for summer activities with educational merit should consider bringing children to watch the teams at work—it’s the kind of authentic local experience that builds environmental literacy. If you’re involved in community organisations, schools, or local business chambers in the Guilford builders area or surrounding neighbourhoods, consider partnering with conservation groups to amplify awareness during swan upping season. Whether you’re undertaking loft conversion projects in riverside properties or managing other local development, understanding Thames conservation efforts helps ensure future projects align with environmental standards. Keep an eye on BBC Radio Surrey and local community calendars for specific dates and viewing locations for this year’s event.
