The Canary Islands, known for their year-round pleasant climate. Pristine beaches, and dramatic volcanic landscapes, have recently been facing increasing occurrences of weather warnings. These alerts range from extreme heatwaves to sudden torrential rain events driven by meteorological phenomena like DANA (Depresión Aislada en Niveles Altos). Understanding Canary Islands weather warnings is crucial not just for residents but also for tourists who visit the archipelago throughout the year. In this article, we’ll explore the different types of weather warnings issued in the Canary Islands. Their causes, potential impacts, and how residents and travelers can stay safe. We’ll also look at recent incidents and forecasts, especially those related to Canary Islands weather warnings DANA and Canary Islands extreme heat alerts.
The Climate of the Canary Islands: A Quick Overview
Situated off the northwest coast of Africa but belonging to Spain, the Canary Islands enjoy a subtropical climate, making them a year-round destination for sun seekers. The islands typically experience mild winters and warm summers, with average temperatures ranging between 18°C (64°F) in winter and 30°C (86°F) in the summer. The pleasant weather, combined with relatively low humidity, makes it ideal for outdoor activities. However, in recent years, the islands have faced abnormal weather patterns, resulting in an increase in Canary Islands weather warnings. These changes are often attributed to climate change and other global atmospheric shifts, contributing to a rise in extreme weather conditions across the region.
What Are Canary Islands Weather Warnings?
Weather warnings in the Canary Islands are issued by AEMET (Agencia Estatal de Meteorología), Spain’s national meteorological agency. These alerts are color-coded (yellow, orange, and red) to indicate the severity of the weather event. Yellow warnings are issued for potentially dangerous weather, orange for more severe conditions, and red warnings for extreme weather that poses a significant threat to life and property. These warnings may be issued for a variety of reasons including heavy rainfall, strong winds, sandstorms (known locally as calima), and extreme heat alerts. In recent years, more frequent and intense occurrences of DANA storms have been a growing concern, leading to widespread disruptions across several islands.
What Is DANA and Why It Matters?
DANA, short for Depresión Aislada en Niveles Altos, is a weather phenomenon that occurs when a mass of cold air separates from the main jet stream and settles in higher layers of the atmosphere. When this cold air interacts with warmer surface air, it can cause severe storms, torrential rainfall, and flash flooding. In the Canary Islands, DANA storms are particularly disruptive because the islands’ rugged volcanic terrain can cause heavy water runoff, leading to landslides and flooding in low-lying areas. These storms are unpredictable and can occur rapidly, making Canary Islands weather warnings DANA essential for public safety. The last few years have seen multiple DANA incidents, causing significant damage to infrastructure and prompting evacuations in affected regions.
Canary Islands Extreme Heat Alert: Rising Temperatures and Their Impact
While DANA storms bring heavy rain and flooding, the Canary Islands extreme heat alerts are equally concerning. Issued when temperatures are forecasted to exceed safe thresholds, these alerts are becoming more frequent due to climate change. During the summer months, particularly in July and August, temperatures can soar above 40°C (104°F), especially in inland and southern parts of islands like Tenerife and Gran Canaria. Such conditions are not only uncomfortable but also hazardous, increasing the risk of heatstroke, dehydration, and wildfires. In recent years, AEMET has issued multiple red-level extreme heat alerts, urging residents and tourists to avoid outdoor activity during peak hours, stay hydrated, and follow public health guidelines. The government also prepares by opening cooling centers and restricting activities like barbecuing in forested areas to prevent fires.
How Calima Events Worsen Weather Conditions
In addition to DANA storms and heatwaves, the Canary Islands are occasionally affected by calima—a weather event where dust-laden winds from the Sahara Desert blow across the islands. These winds can significantly reduce air quality, affect visibility, and exacerbate respiratory problems for sensitive individuals. During a calima, the sky turns a hazy yellow or orange, and the temperatures can feel even more oppressive due to the dry, dust-filled air. When calima coincides with a Canary Islands extreme heat alert, the impact can be particularly severe. Combined, these phenomena often lead to Canary Islands weather warnings being upgraded and emergency services being put on high alert to assist those in distress and to mitigate potential fire hazards.
Recent Weather Disruptions in the Canary Islands
In the past couple of years, the Canary Islands have experienced a string of weather-related emergencies. In early 2024, a significant DANA storm hit the islands of La Palma and Tenerife, causing widespread flooding, power outages, and travel disruptions. Roads were closed, schools were shut down, and emergency crews were deployed to help residents evacuate low-lying areas. Meanwhile, the summer of 2025 was marked by an extended extreme heat alert period where temperatures reached record highs, particularly in the islands of Fuerteventura and Lanzarote. Several cases of heatstroke were reported, and authorities were forced to cancel public events and issue stay-at-home advisories. These incidents highlight the growing importance of Canary Islands weather warnings and the need for both residents and tourists to take them seriously.
How the Government Responds to Weather Warnings
When a Canary Islands weather warning is issued, the regional government activates its emergency response protocols. This includes deploying the military emergency unit (UME), firefighters, and local police to monitor and manage the situation. Public transport may be suspended, schools may be closed, and public gatherings may be cancelled to reduce risk. Additionally, authorities use various platforms—TV, radio, social media, and emergency SMS services—to keep the public informed. In the case of DANA storms, residents are advised to avoid riverbeds and areas prone to flooding. For extreme heat alerts, shelters with air conditioning are opened to help vulnerable populations. Including the elderly and those without access to cooling systems at home.
Tips for Tourists During Weather Warnings in the Canary Islands
If you’re planning a trip to the Canary Islands, it’s essential to stay updated on weather conditions. Tourists are often unaware of how severe weather events can affect their travel plans and personal safety. Here are some important tips:
- Always check the AEMET website or app for the latest Canary Islands weather warnings.
- Avoid hiking or exploring mountainous regions during DANA storms due to landslide risks.
- During heatwaves, stay indoors between 12 PM and 5 PM, drink plenty of water, and avoid alcohol.
- Keep emergency contact numbers handy and follow the guidance of local authorities.
- Subscribe to alert systems or hotel notifications that can provide real-time updates during your stay.
Being prepared and cautious can ensure that you enjoy your vacation safely, even when the weather doesn’t cooperate.
Environmental Impact of Extreme Weather in the Canary Islands
The increase in extreme weather events is also taking a toll on the Canary Islands’ environment. Flash floods from DANA storms erode soil and damage delicate ecosystems, especially in forested national parks. Prolonged heatwaves stress native plant species and reduce agricultural yields, impacting local farmers and the economy. Wildfires have also become more frequent during summer months, with entire tracts of land burned. Displacing wildlife and threatening rural communities. These consequences underline the importance of proactive environmental and climate policies. The local government has initiated reforestation programs and improved water management systems. But experts warn that more needs to be done to address the root causes of climate instability affecting the islands.
Role of Climate Change in Intensifying Canary Islands Weather Warnings
Scientists and meteorologists agree that climate change is a significant factor behind the increase in Canary Islands weather warnings. Rising global temperatures lead to more evaporation, which in turn feeds into extreme weather events like DANA storms. Similarly, the warming of oceans contributes to more intense heatwaves and shifts in atmospheric pressure systems. According to recent climate studies, the Canary Islands are expected to see a 15–20% increase in severe weather events by 2030 unless drastic measures are taken to reduce greenhouse gas emissions. Public awareness, combined with stronger environmental policies, is essential to mitigate the long-term risks posed by this trend.
The Economic Cost of Weather Warnings and Disasters
Weather-related disruptions in the Canary Islands also have a significant economic cost. Tourism, which is a major industry in the region, is particularly vulnerable. Flight cancellations, hotel evacuations, and damaged infrastructure can lead to millions of euros in losses during a single extreme event. Local businesses, especially those in agriculture and hospitality, also suffer. For instance, during a prolonged heatwave in 2025, crop yields dropped by nearly 30% in some areas. The government has been working to improve infrastructure resilience and emergency response funding, but balancing economic recovery with climate preparedness remains a challenge.
Forecast for the Rest of 2025: What to Expect
Looking ahead, weather forecasts for the remainder of 2025 indicate a continued risk of extreme heat events, particularly in November and December, which traditionally have been milder months. Meteorologists also warn of another potential DANA storm forming in the Atlantic, which could affect the western islands. The public is urged to monitor updates from AEMET and local authorities as these predictions develop. Climate experts emphasize the importance of planning ahead, especially during peak tourist seasons, to avoid getting caught in sudden weather changes. Preparedness remains key as the Canary Islands weather grows increasingly unpredictable.
