Have You Heard of Cold Water Shock?

August 11, 2020

A quarry lake can be very cold even on a hot summer's day. You could die from 'Cold Shock' in less than 2 minutes.

Last weekend the RNLI reported their highest ever level of incidents in one day, so we are taking this opportunity to help raise awareness of the dangers and the precautions you and your family can take.


During any time of the year, it is important to be aware of the dangers open water can bring, however, during the summer months, with hotter weather and more people heading to open water, it is even more critical to spread the awareness and make people aware of the safety tips. The RNLI and RLSS have both published safety guides, with the RNLI ‘Float to Live’ video, demonstrating how floating whilst the cold-water shock passes can increase the chances of staying alive. The RLSS also have a Water Safety Code reminding you to think twice before entering open water.


With people looking to local sites for a quick dip, for many this may mean quarry lakes. Even during hot weather, these remain extremely cold due to the depths of the water. For Quarry Operators, this is an important time to stay vigilant and check all safety measures are in place. If you know anyone that is tempted to head down for a quarry swim, be sure to pass on the MPA’s cold water shock which clearly demonstrates the risks of swimming in cold water. This will hopefully make people think twice.

World Day to combat Desertification and Drought 2025

By Rachael Plant • June 17, 2025
Desertification and drought are two of the most pressing environmental challenges of the 21st century. Exacerbated by climate change, the devastating effects of both can be felt across the globe, with an estimated 40% of the world's population impacted by water scarcity events. As global temperatures continue to rise, and severe weather events increase, regions across the globe face the potential for increased frequency and severity of droughts, often progressing rapidly and unexpectedly. As of 29th May this year, a drought was officially declared in parts of the UK, having experienced the driest start to Spring in over 130 years. Whilst the recent rainfall at the start of June has helped to stabilise concerns, uncertainty for the months ahead still remain. How is the UK landscape affected by drought?
