The Canary Islands are one of Europe's safest, easiest places to take a holiday. Crime against tourists is low, the tap water is generally fine, the health care is good, and for the vast majority of visitors the biggest hazard is nothing more sinister than too much sun on day one. Still, a little local knowledge goes a long way — knowing why the sun bites harder here than it looks, how to read a beach flag, and what number to call if something does go wrong. This guide keeps things calm and practical so you can spend your time enjoying the islands rather than worrying about them.
The sun is stronger than it feels
This is the single most important thing to understand, and the one that catches out the most people. The Canaries sit at a subtropical latitude, far south of mainland Europe and roughly level with the Sahara, so the sun climbs high and the ultraviolet is genuinely fierce — often much stronger than the pleasant sea breeze makes it feel. You can burn badly on a hazy day, in the water, or after a cloudy morning, and the cooling trade winds mask the damage until it's done. Children, fair skin and bald heads suffer first.
Because of the subtropical latitude, UV levels here can be high even in winter and even when it feels mild. Treat the sun with respect year-round: a burn on the first afternoon can spoil a whole week.
The fix is simple and cheap. Use a high-factor, water-resistant sun cream and reapply it after swimming; wear a hat and sunglasses; seek shade in the middle of the day; and drink more water than you think you need.

Beaches, flags and rip currents
Canary beaches range from calm, sheltered bays to open Atlantic strands with real surf, so conditions vary hugely from one cove to the next. Lifeguarded beaches fly a simple flag system that you should always check before going in — it's the clearest, most reliable safety information you'll get.
| Flag | What it means |
|---|---|
| Green | Safe to swim — conditions are calm. |
| Yellow | Caution — swim carefully, stay near the shore, watch for currents. |
| Red | Danger — do not enter the water. |
The Atlantic is not the Mediterranean. Some of the loveliest wild beaches, especially on the exposed north coasts, have powerful waves and rip currents that can pull even strong swimmers out. If you're caught in a current, don't fight it head-on — stay calm, float, and swim parallel to the beach until you're free of the pull, then come in at an angle. Sheltered, family-friendly options such as Amadores and Las Teresitas are far gentler than the open ocean; our beaches guide flags which are calm and which are for confident swimmers.
A red flag is not advisory — it's a genuine warning that people drown ignoring. If in doubt, sit it out and enjoy the beach from dry sand.
Jellyfish and the odd man o' war
Jellyfish are occasional rather than constant, and most visits pass without a single sighting. Now and then, wind and currents push a bloom towards shore, and very occasionally the Portuguese man o' war — a striking blue-purple float with long trailing tentacles — drifts in. Its sting is painful, so never touch one on the sand, and keep children away, as the tentacles sting even when the creature looks dead. If you're stung, leave the water, rinse with seawater (not fresh water), carefully remove any tentacles, and seek help from a lifeguard or pharmacy. When a beach posts a jellyfish warning, take it seriously and stay out.
Water, food and everyday health
Tap water in the Canaries is treated and generally safe to drink, though much of it comes from desalination and the taste can be flat or faintly mineral, so plenty of visitors and locals prefer bottled water. Cooking and brushing teeth with tap water is fine. The food is a genuine highlight rather than a hazard — tuck into papas arrugadas with mojo and the rest of the local cooking with confidence. As anywhere warm, the usual sensible habits apply: wash hands, keep hydrated, and don't overdo the sun and sangria on the same afternoon.
Pharmacies, doctors and the emergency number
Spanish pharmacies — look for the green cross and the sign farmacia — are excellent and everywhere in the resorts. Pharmacists are highly trained and can advise on minor ailments, sunburn, stomach upsets, bites and stings, and many medicines are available over the counter that might need a prescription at home. Towns run a rota so there's always a duty pharmacy (farmacia de guardia) open out of hours; the roster is posted on every pharmacy door.
The all-purpose emergency number across the Canaries (and the whole EU) is 112. Operators speak Spanish and English, and it covers ambulance, police and fire. Save it in your phone on arrival.
For anything more serious there are modern hospitals on the main islands and clinics in the resort areas; on the smaller islands, care is good but a serious case may mean transfer to a larger island, another reason not to leave insurance to chance.
Insurance, EHIC and GHIC
As Spanish territory in the EU, the Canaries honour the European Health Insurance Card (EHIC) and the UK's Global Health Insurance Card (GHIC), which give EU and UK visitors access to state health care on the same basis as residents. Carry your card, but don't treat it as a substitute for travel insurance: it won't cover private clinics, repatriation, cancelled flights or lost baggage. Take out proper travel insurance as well, and make sure it covers any activities you're planning — hiking, watersports or diving — before you go.
Calima, asthma and air quality
Every so often an easterly wind carries fine Saharan dust across the islands. This calima brings a sudden jump in heat and a hazy, milky sky, and while most are mild and pass within a day or two, the dust can bother anyone with asthma, allergies or a chest condition. On a strong calima day, keep windows shut, stay indoors more, carry any inhalers you rely on, and go gently outdoors. For most people it's simply an unusually hot, dreamy-hazy interlude; we cover it in more depth under best time to visit.
Getting around safely
Roads are good but the terrain is dramatic — expect steep mountain routes, hairpins and the odd sea mist on high ground. Drive to the conditions, watch for fatigue after a day in the sun, and don't rush blind bends. Our getting around guide covers buses, hire cars and ferries in detail. Beyond that, the Canaries ask little of you: sensible sun care, respect for the Atlantic, and the number 112 in your pocket are really all you need to stay safe and relaxed.
