Jersey is set to mark another year of rising temperatures by adding a new red stripe to the Jersey Climate Stripes wall at the Waterfront. The addition comes after 2024 was recorded as the island’s seventh warmest year on record, with an average temperature of 12.95°C, according to data from the Jersey Met Office.
The Maison Louis Observatory has been recording official temperatures in Jersey since 1894, and the latest data continues to show a warming trend. Paul Aked, head of meteorology, explained that the daily maximum temperatures in 2024 were 0.32°C above the long-term average, while night-time minimum temperatures were even higher at 0.81°C above the historical norm.
Aked emphasized the significance of these rising night-time temperatures, stating that they are contributing to an overall increase in annual temperatures. He further noted that warmer temperatures lead to a greater capacity for the atmosphere to hold moisture, which could contribute to wetter conditions and an increased risk of extreme weather events.
The Jersey Climate Stripes wall, a powerful visual representation of the island’s warming trend, will soon display 131 stripes, each representing a year from 1894 to 2024. The new red stripe will be added on 18 January 2025. The wall serves as a stark reminder of how the island’s climate has changed over time, transitioning from predominantly blue and light shades to darker reds and oranges.Aked emphasized the significance of these rising night-time temperatures, stating that they are contributing to an overall increase in annual temperatures.

Environmental Concerns and Call to Action
Environment Minister Steve Luce expressed concern over the increasing temperatures and their potential effects on biodiversity, food security, and rising sea levels—challenges that are particularly significant for an island like Jersey.
“With increasing temperatures come associated impacts on biodiversity, food security, and sea levels which, as an island, is greatly concerning,” Luce stated. He reiterated the government’s commitment to reducing Jersey’s carbon footprint and urged islanders to take action in their daily lives.
“We must ensure Jersey remains on a pathway to net zero by 2050, in line with the internationally recognized targets of the Paris Agreement,” he added.
The ongoing rise in temperatures highlights the urgent need for climate action. The Jersey Climate Stripes wall serves as a compelling visual reminder of the long-term trends affecting the island. As the government continues its push towards sustainability, the community will play a vital role in reducing emissions and preparing for the challenges posed by climate change.
