South vs North Facing in Spain 2026: Orientation, Heat and Resale

The noon sun swings around 47 degrees between the solstices, everywhere on earth. Latitude decides where that range sits, and at 38 degrees north it runs from 75 degrees in late June down to 28 just before Christmas. At 75 degrees a balcony above projecting 1.2 m throws a shadow roughly 4.6 m down the wall, enough to cover a patio door. At 28 degrees it shades about 65 cm and the winter sun walks straight in. So a south flat with the terrace above overhanging is textbook passive solar, and a south flat with a flush facade is a greenhouse from June to September.

Spain keeps Central European Time on the Greenwich meridian, so solar noon here falls near 14:00 in summer. Every hour below is clock time.

South takes a steep sun in summer, so the facade absorbs heat but the openings shade cheaply with an overhang or a toldo. In winter it collects sun from around 08:30 to 17:45 and pushes it deep into the room. For winter use the rule is simply correct.

Southeast and east take sun from first light to around midday, then drop into shade: a sunny terrace at breakfast, a shaded one from 14:00 through the worst of the August heat. Southeast also catches the December sunrise almost square on, because the winter sun rises well south of east. Local architects favour it, and so do we.

West punishes you in high summer. Peak air temperature on an August day lands around 17:00 to 18:00, and by 18:00 the sun still sits about 33 degrees up in the west-southwest, aimed straight at the wall. At 19:00 it is 21 degrees up, at 20:00 about 10, low enough to come in under any awning, and it does not set until close to 20:50. A west terrace in August is furniture storage until nine in the evening. What you buy in exchange is the sunset and the best spring and autumn terrace on the coast, worth real money if April, May and October are your months.

North gets no direct sun on the facade between late September and late March. In June and July it takes a low, oblique sun soon after sunrise and again before sunset, because midsummer sun rises about 30 degrees north of due east. What you get instead is flat, glare-free light and a room several degrees cooler than the rest of the block, which is why remote workers ask for north more often than you would expect. The price is January and the heating bill.

Which months you use it decides everything

The south-facing rule comes from people short of sun. Here the problem is often the opposite. A buyer who comes only in July and August is fighting heat, not darkness: north, northeast and east all work, and a west living room opening onto a west terrace is the worst pick available. A snowbird here from November to March wants south or southeast outright. A full-time owner needs both, which is why the standard Spanish plan puts the living room south or southeast and the bedrooms north or east. North carries one drawback sellers skip past: a wall that never sees the sun collects condensation, and on ground floors mould behind the wardrobe.

The age of the building decides how much any of this matters. Most Costa Blanca resale stock went up between 1998 and 2007, before the energy sections of the Código Técnico de la Edificación applied, so orientation does the work the insulation is not doing. A west wall on a 2023 block is an annoyance; on a 2004 block it is why the owner sleeps in the back bedroom. Read the cooling demand figure on the certificado de eficiencia energética, not just the letter. The electricity gap is small, perhaps EUR 40 to EUR 60 a month in August, and the running costs that matter sit elsewhere, as we set out in villa versus apartment: the real annual cost.

The resale premium exists whether it is deserved or not

In the same block, south and southeast units ask more and go first, while north and northwest ones sit longest and take the offers. A spread of roughly 5% to 10% between the best and worst aspect in one building is normal on the southern Costa Blanca. If your months are July and August, that discount is yours to take. Be honest about what it is, though: you will sell into the same preference you bought against, so count it as cheaper comfort rather than a gain you realise on exit.

The terrace, the pool and what to check on a viewing

The flat's orientation and the terrace's are two separate facts, and the terrace usually matters more. A planta baja can have a north living room and a west patio. A wrap-around ático terrace has two or three aspects and nothing above it shading the glass, while a roof solarium takes sun from every direction at once and is unusable in August until eight. A pool on the south or west side of the plot stretches the swimming season into May and October.

What stands in front of the window can beat the compass outright. A five-storey block 15 m to the south cuts off everything below about 31 degrees, and the December sun only climbs to 28, so the second-floor flat behind it gets no winter sun at all. On hillsides the slope matters as much: above Benidorm on Sierra Cortina, where WES-2452D Sierra Cortina apartment, 3-bed 116 m2, EUR 495,000 sits, two units on the same bearing lose the evening sun an hour apart.

On the viewing itself:

• A February viewing tells you little about August: the noon sun sits nearly 30 degrees lower and rises well south of east.
• Look for a fitted toldo, bleached terrace plastic, warped shutters. If one side of the estate carries awnings and the other does not, you have found the hot side.
• Ask a neighbour, not the seller, what time the sun leaves the terrace in August.

Torrevieja is the best place to price this directly, because one block often holds units on three aspects at once: Torrevieja sale listings.

Frequently asked questions

Is a south-facing house always better in Spain?

No. South is best for winter, because the December sun sits about 28 degrees above the horizon and reaches deep into the room. In July and August it works against you unless the glass has a real overhang or an awning.

Why is west-facing worse than south-facing on the Costa Blanca?

Peak air temperature arrives around 17:00 to 18:00. At 18:00 the August sun still sits about 33 degrees up in the west-southwest, aimed at the wall, too low for an overhang to block. The terrace stays unusable until close to nine.

Do north-facing apartments in Spain sell at a discount?

Usually yes, roughly 5% to 10% below the best-oriented unit in the same block. Summer-only owners genuinely prefer north for the cool, even light. You buy at the discount and you sell into it, so treat it as cheaper comfort, not a resale gain.

How do I check orientation properly on a viewing?

Stand on the terrace with your phone compass, not in the living room, and note the clock time. Spain runs Central European Time from the Greenwich meridian, so summer solar noon falls near 14:00.
