You've probably heard the brochures call it the "Land of Eternal Spring." Honestly, it’s one of the few times travel marketing isn't lying through its teeth. But if you think that means every beach on every island is a scorching paradise 365 days a year, you’re in for a cold, windy surprise.
The weather in Canary Islands is weirdly diverse. You can be shivering in a mist-covered laurel forest in the morning and getting a sunburn on a sand dune by lunch. It's not just "hot" or "not." It’s a complex dance of African heat, Atlantic currents, and trade winds that locals call the Alisios.
Basically, the archipelago acts like a giant laboratory for microclimates.
Why Weather in Canary Islands Isn't What You Expect
Most people check the forecast for "Tenerife" and see 22°C. They pack flip-flops and a tank top. Then they land in the north, near La Laguna, and realize it’s 14°C, drizzling, and everyone is wearing a light down jacket.
This happens because the high islands—Tenerife, Gran Canaria, La Palma—act like massive walls. The moist trade winds hit the northern slopes, get stuck, and form what locals call the Panza de Burro (the Donkey's Belly). It's a thick, gray ceiling of clouds that keeps the north lush and green but definitely not "tropical beach" weather.
Meanwhile, just 45 minutes south, the sky is a piercing blue. The mountains have blocked all that moisture. It’s a totally different world.
The Sahara Factor: Enter the Calima
Every now and then, the wind flips. Instead of the cool Atlantic breeze, you get the Calima. This is a hot, dry wind blowing straight from the Sahara Desert.
- It carries fine orange dust.
- Temperatures can spike 10 degrees in hours.
- Visibility drops to almost zero, sometimes grounding flights.
- Your throat gets scratchy, and your eyes might itch.
In February 2020, a Calima was so bad it looked like Mars outside. Most of the time, though, it’s just a hazy couple of days where the air feels like a hairdryer. If you have asthma, keep your windows shut. Seriously.
Month-by-Month: The Reality Check
Don't trust a generic "average" chart. Here is how the weather in Canary Islands actually feels when you're standing on the pavement.
January and February
It's the "winter," but don't call it that to a Canadian. Daytime highs in the south of Gran Canaria or Tenerife usually hover around 21°C. The sea is about 19°C. Brisk? Yes. Swimmable? For the brave. At night, it drops to 14°C or 15°C. You need a hoodie for dinner. No exceptions.
March and April
Spring is when the islands truly wake up. You’ll see more flowers than you knew existed. Rain is still a possibility, especially on the western islands like La Palma or El Hierro. Temperatures start creeping toward 23°C. It’s peak hiking season because you won't melt while climbing a volcano.
May and June
This is the "sweet spot." The summer crowds haven't arrived, but the sun is consistent. Expect 24°C to 25°C. The water is finally warming up.
July and August
It gets hot. Not "Dubai hot," but a solid 28°C to 30°C. The trade winds are strongest now, which is why world-class windsurfing championships happen in Fuerteventura and Pozo Izquierdo (Gran Canaria) during these months. If you hate wind, stay away from the east coasts.
September and October
Locals love this time. The winds die down, the ocean is at its warmest (around 23°C), and the air is still a balmy 26°C. It’s the best time for diving or long swims.
November and December
While London is freezing, the Canaries are still hitting 22°C. It’s bizarre to see Christmas trees next to palm trees in short sleeves, but that’s the vibe. This is also when the "winter storms" can hit—usually just a day or two of heavy rain that turns the hills neon green.
Choosing Your Island Based on the Sky
If you want sun and nothing but sun, head to Lanzarote or Fuerteventura. They are flat. They don't have big mountains to catch the clouds. They are basically extensions of the Sahara.
Tenerife is the king of variety. You can go from the snowy peak of Mount Teide (3,715 meters) to the baking sun of Playa de las Américas in one afternoon. If you stay in the north (Puerto de la Cruz), expect it to be cloudier and more humid.

Gran Canaria is often called a "miniature continent." The south (Maspalomas, Puerto Rico) is a sun-trap. The center is rugged and cool. The north is a bustling, often overcast, urban hub.
La Palma, La Gomera, and El Hierro are for the people who want to sweat from walking, not from lying on a towel. They are wetter, greener, and much more temperamental.
Sea Temperatures and Swimming
The Atlantic isn't the Mediterranean. It never gets "bathwater" warm.
- Winter: 18°C - 19°C (Fresh!)
- Summer: 22°C - 24°C (Perfect)
If you’re planning on surfing, you’ll want a 3/2mm wetsuit in the winter. In the summer, you can get away with a shorty or just board shorts if the sun is out.
Actionable Tips for Your Trip
Stop obsessing over the 10-day forecast. In the Canaries, the forecast often shows a "cloud" icon every single day. This just means there might be a cloud in the sky at some point. It rarely means a washout.
Pack Layers
Even in August, if you go up into the mountains to watch the sunset, you will be freezing without a jacket. Altitude changes everything here. For every 100 meters you climb, the temperature drops significantly.
Check the AEMET Website
The Spanish State Meteorological Agency (AEMET) is much more accurate for local quirks than your iPhone’s default weather app. They track the Calima alerts and wave heights better than anyone else.
Follow the "Sun-Seeking" Rule
If it’s raining where you are, drive 30 minutes south. In 90% of cases, you’ll find the sun. The mountains are your friends or your enemies, depending on which side of them you stand.
Book the South for Winter
If you are coming between December and March for a beach holiday, do not book a villa in the north of any island. You’ll spend the week looking at the sun in the distance while sitting under a cloud. Stick to Costa Adeje (Tenerife), Maspalomas (Gran Canaria), or Playa Blanca (Lanzarote).
The weather in Canary Islands is predictable in its unpredictability. It’s a place where you can find exactly the climate you want, as long as you’re willing to drive a few miles to find it.
Next Steps for Your Trip:
- Check the AEMET forecast for the specific municipality you're visiting, not just the island name.
- If visiting between January and March, pack one heavy hoodie and one windbreaker—you'll use both.
- Download a star-gazing app; the clear skies over the peaks (above the clouds) offer some of the best views in the Northern Hemisphere.
