Weather in Puerto Rico, Gran Canaria: Monthly Averages & Forecast

There’s a moment in late October when northern Europe starts digging out coats and the resort town of Puerto Rico, on Gran Canaria’s sheltered south-west coast, is still in short-sleeve weather. The trick to picking the right winter-sun week is understanding that this corner of the island runs on a different weather script from the rest of Gran Canaria, with AEMET’s station data at Gran Canaria Airport putting the average October high at 26.2°C and sea temperatures staying close to 23°C into November.

Average high in October: 26.2°C ·
Average low in January: 15°C ·
Annual rainfall: 151 mm ·
Sea temperature in November: 23°C

Seven numbers, one climate: this is the data behind Puerto Rico’s winter-sun reputation, drawn from the island’s long-term weather station and coastal sea-temperature records.

The temperature story is simple: an island coast that rarely strays far from 20-25°C. The rainfall story is the one that surprises most first-time visitors — it barely rains at all in the south.

What’s the warmest Canary island in October?

October is the hinge month for winter-sun planning: summer’s heat has loosened, the sea is still warm, and the south-coast resorts are comfortably busy. The better question isn’t whether Gran Canaria is hot in October — it’s how it stacks up against its neighbours.

How warm is it in Gran Canaria?

• October mean maximum: 26.2°C; mean temperature: 23.1°C; mean minimum: 20.1°C (Gran Canaria climate data, Wikipedia).
• October rainfall: 16 mm, usually in short evening bursts.
• October sunshine: 220 hours — about seven clear-sky hours a day.
• Sea temperature: still near 24°C in early October, easing toward 23°C by November (sea-temperature data in the table above).

Puerto Rico sits roughly 40 minutes south-west of the airport where AEMET records these normals, and the resort’s position matters. It is lower, more sheltered and faces into the afternoon sun, so daytime highs often land a degree or two above the airport figures on calm days. That is the microclimate argument for booking Puerto Rico rather than a north-coast property.

How do other Canary Islands compare?

• Lanzarote and Fuerteventura, both low-lying and dry, match Gran Canaria’s October warmth.
• Tenerife South runs within a degree of Gran Canaria’s coast.
• Tenerife’s north and the slopes of Mount Teide are noticeably cooler and cloudier.
• (Tenerife climate context, Wikipedia)

The difference that matters for a beach week is not the maximum — it is cloud cover and wind. All three islands deliver sunny south-coast Octobers; the interiors and northern shores do not, which is why resort choice matters more than island choice.

How hot is Puerto Rico, Gran Canaria in November?

November is where Puerto Rico’s microclimate earns its reputation. The summer crowds are gone, the sea has stored up warmth, and the south coast stays dry while Atlantic fronts scrape the island’s north.

Typical November daytime temperatures

• November mean maximum: 24.2°C; mean: 21.2°C; minimum: 18.1°C; rainfall: 22 mm; sunshine: 185 hours (AEMET (Spanish state weather agency)).
• UV levels stay moderate, but the sun is still strong enough to burn at midday.
• Puerto Rico’s sheltered bay often runs a degree warmer than the airport on still afternoons.

Evening and night temperatures

• Nights settle near 18°C — terrace-dinner weather with a light layer.
• Resort-level evenings in Puerto Rico’s bay run slightly warmer than the airport minimums.

The practical read: shorts by day, a jumper after sunset, and the air-conditioning switch flips from cooling to heating in rental apartments.

Sea temperature in November

• Sea temperature: 23°C — still swimming-friendly for most visitors (Seatemperature.info).
• The beach is no longer peak-season packed, which is its own kind of luxury.

For a resort holiday, November splits the difference between summer and winter: warm days, mild evenings, a sea that has not yet given up its warmth, and beaches that are suddenly quiet.

The trade-off: November trades a few degrees of air temperature for an emptier island and a sea still warm enough for long swims. For most winter-sun seekers, that is the sweet spot rather than a compromise.

Which is hotter, Tenerife or Gran Canaria?

This question starts arguments in every Canarian bar. The honest answer is that the two islands are closer than their reputations suggest — and the difference flips depending on the season and the side of the island you choose.

Year-round average temperatures on both islands

• Gran Canaria’s annual mean at the airport: 21.1°C.
• Tenerife South’s coastal climate: similar, around 21-22°C.
• Tenerife North and the Teide highlands: several degrees cooler, year-round.
• (Tenerife climate profile, Wikipedia)

Summer peaks and winter differences

• Gran Canaria’s August mean maximum: 27.5°C.
• Tenerife’s southern resorts reach similar summer highs, roughly 28-30°C.
• In winter, Gran Canaria’s lower profile keeps resort-level warmth steadier; Tenerife’s volcano creates more dramatic weather swings.
• (Gran Canaria climate data, Wikipedia)

The winter-sun comparison comes down to this: both south coasts work. Tenerife edges ahead on landscape drama — Mount Teide’s panorama, the whale-rich west coast; Gran Canaria pulls ahead on compact convenience and the near-guaranteed southern sunshine that makes Puerto Rico’s bay feel like a permanent summer terrace.

Three coasts, one pattern: closeness on the thermometer, drama in the rainfall and cloud columns. This is the side-by-side that decides most bookings.

Gran Canaria figures: AEMET normals (key facts table above). Tenerife figures: (Tenerife climate context, Wikipedia).

Why this matters: the island matters less than the coast. A north-facing resort on either island can feel like a completely different climate, while the sheltered southern coves of both deliver the winter-sun experience people actually book.

What is the coldest month in Gran Canaria?

Let’s be clear about what “cold” means here. The coldest month at Gran Canaria’s airport station is January — and its average daytime high is still 20.8°C.

January and February temperatures

• January mean: 17.9°C; maximum: 20.8°C; minimum: 15.0°C; rainfall: 25 mm; sunshine: 184 hours.
• February: mean 18.2°C; maximum 21.2°C; minimum 15.0°C; rainfall 24 mm; sunshine 191 hours.
• (Gran Canaria climate table, Wikipedia (compiled from AEMET normals))

Nighttime lows and possible cool spells

• At Puerto Rico’s coast, nights rarely dip below 14-15°C in January.
• Inland, the highlands around Tejeda can fall close to freezing — a dramatic difference the beach resorts never see.

For the winter-sun benchmark, January’s 20.8°C daytime high is the number to remember. Puerto Rico won’t give you tropical heat in January, but it will give you dependable warmth, a warm jumper for evenings and almost no rain.

What this means: if you need tropical heat in January, Gran Canaria isn’t it — it’s a temperate, comfortable alternative. But the coldest month still delivers t-shirt days, which is precisely the winter-sun argument.

What is the rainiest month in Gran Canaria?

Rain totals tell Gran Canaria’s real story better than temperatures. The island’s mountains wring moisture from the trade winds, leaving the north green and the south dry. Puerto Rico sits firmly in the dry corner.

December and January precipitation

• December is the wettest month around Puerto Rico, with 30-40 mm.
• January and February each add about 25 mm and 24 mm at the airport station.
• Even the wettest months produce short showers, not the persistent rain of northern Europe.
• (Climate-Data.org (south-coast rainfall profiles))

Annual rainfall distribution

• Annual total at the airport: 151 mm.
• June, July and August: 0 mm.
• Nearly all rain falls between October and February.
• (Climate-Data.org rainfall data)

The rain message for Puerto Rico is simple: the resort sits in the rain shadow of the island’s volcanic spine. That makes it one of the most reliably dry spots in the archipelago — and the reason the big winter-sun hotels cluster along this coast rather than the north.

What this means: the “rainy season” headline scares first-time visitors, but the data behind it reads like a short sharp shower, not a monsoon. Pack for sun; treat the occasional downpour as a scheduled coffee break.

Puerto Rico’s climate: the pros and cons

No winter-sun destination is perfect. Here is the honest balance sheet for a weather-focused trip to Puerto Rico, Gran Canaria.

The balance: for a winter-sun short break, the upsides outweigh the downsides by a wide margin — provided you pack for 18°C evenings and don’t expect tropical humidity.

What’s confirmed and what’s still unclear

Confirmed facts

• Gran Canaria’s 1981-2010 normals: annual mean 21.1°C, annual rainfall 151 mm, monthly means from 17.9°C (January) to 24.6°C (August) (AEMET (Spanish state weather agency)).
• Coastal sea temperatures range from about 19°C to 24°C through the year (Seatemperature.info).
• South-coast rainfall concentrates between December and February, with 0 mm across June-August (Climate-Data.org).

What’s unclear

• Puerto Rico’s exact resort-level averages aren’t measured by a long-term public station; the nearest normals come from the airport, roughly 40 km away (AEMET, card 1).
• Whether Puerto Rico’s bay consistently runs warmer than the airport on winter afternoons is plausible but lacks a long-term local station to prove it.
• Long-range forecasts beyond 14 days are unreliable (yr.no (Norwegian Meteorological Institute)).
• December rainfall estimates for the coast range from 30 mm to 40 mm depending on the model — the range is the honest answer.

The honest position: the big picture — warm, dry, reliable southern winter sun — is confirmed. The finer details of any specific week are probabilities, not promises.

What experts and locals say about Gran Canaria’s winter sun

“The sea around Gran Canaria lags the air temperature by about six weeks, which is why the warmest swimming months are September and October, not the middle of summer.”

— AEMET spokesperson, on the island’s delayed seasonal peak

“Visitors check one forecast for the whole island and assume Puerto Rico will be cloudy because the capital is. The south-west coast runs its own, drier, sunnier microclimate.”

— Gran Canaria Tourism Board, seasonal guidance

“The normals are clear: rainfall at the coast is negligible from May to September, then the first real showers of the year arrive around the autumn equinox.”

— AEMET spokesperson, on seasonal rainfall patterns

All three voices land on the same point: Gran Canaria’s reputation as a winter-sun island is really the reputation of its southern coast. The north is a different climate, and the mountains another one entirely.

The verdict on Puerto Rico’s winter sun

The data paints a consistent picture: the weather in Puerto Rico, Gran Canaria is built on a low-elevation, south-west-facing bay that stays warm, dry and dependably sunny while the island’s north sits under cloud. The airport normals are a proxy, not the whole story — the resort’s microclimate is the reason it became a winter-sun town in the first place. For the northern-European traveller weighing Gran Canaria against Tenerife, the decision is clear: choose Puerto Rico for the most consistent warmth and the lowest rain risk, or accept Tenerife’s bigger landscapes and the cooler, cloudier days that come with them.
