The “calima” is a meteorological phenomenon characteristic of the Canary Islands that occurs when a warm and dry air mass laden with particles from the Sahara Desert moves towards the archipelago. Over the last 40 years, a decrease in the frequency of calima episodes in the Canary Islands has been observed, leading to a situation where, although less frequent, episodes are more intense.
This change in the frequency and intensity of the calima in the Canary Islands may have various causes, including global factors such as climate change. Scientific studies suggest that the rise in the temperature of the Atlantic Ocean and the weakening of the trade winds are contributing to the decrease in calima episodes in the Canary Islands.
Despite the decrease in the frequency of calima episodes, it is important to remember that this meteorological phenomenon remains part of the identity of the Canary Islands and can have a significant impact on people’s health and air quality. Therefore, it is essential for both residents and visitors to be informed on how to protect themselves during a calima episode.
If you find yourself in the Canary Islands during a calima episode, it is recommended to limit outdoor exposure, close windows and doors to prevent the entry of suspended particles, and use masks to protect the respiratory system. Moreover, it is important to stay hydrated and pay attention to any symptoms related to calima exposure, such as eye irritation or respiratory problems.
Despite the changes in the frequency and intensity of calima in the Canary Islands over the past 40 years, this phenomenon remains an important part of the Canarian experience. While it is impossible to predict with certainty when the next calima episode will occur, being informed and prepared can help minimize its negative effects. Enjoy your stay in the Canary Islands and stay safe during calima episodes!
