Spain is experiencing an unusual phenomenon: a second wave of abnormally “summer-like” heat this winter, with temperatures in some places rising to nearly 30 degrees Celsius. This event is a direct consequence of global warming. Despite a slight dip after the December heat, January temperatures remain high, creating an almost-summer feeling among residents and tourists. In many coastal areas, people actively visit beaches to sunbathe and swim in the sea.
Second “summer” warm spell this winter
Temperatures climb close to 30°C in some areas, especially noticeable along the coast.
AEMET: high pressure + warm air from Africa
Warm air masses and the lack of cloud cover boost daytime heating.
Weekly peak: 29.6°C in Cheste (near Valencia)
Average values run 5–10°C higher than usual across multiple regions.
Bigger trend: extreme warm periods are more frequent
Meteorologists link recurring extremes to broader climate-change patterns.
Coastal vibe: beaches, sunbathing, even swims
With spring-like conditions, many people head straight to the shoreline.
Why it’s so warm: AEMET’s explanation
Spain’s Meteorological Agency (AEMET) explains the phenomenon by the influence of a high-pressure system that transports warm air masses from Africa, as well as the absence of a cloud layer, which contributes to an additional rise in temperatures. This contrasts with the extremely cold weather and rains that have recently affected Spain and other parts of Europe.
Where the highs were recorded and how unusual they are
According to AEMET representative Marcelino Nuñez, Cheste—a small town west of Valencia—recorded the week’s highest temperature: 29.6°C. On average, temperatures across the country range from 10–15°C in northern and mountainous regions to 18–23°C in lowland areas, which is 5–10 degrees higher than normal values. Nuñez emphasizes that the elevated temperatures match a trend of increasing frequency of extremely warm periods associated with climate change.
Wider context: heat records across Europe
It is worth noting that 2023 was the warmest year in the entire history of observations, with the global temperature 1.35°C higher than in the pre-industrial era. Similar warmth was also observed in Ukraine, where December temperatures in Kyiv exceeded the previous record set in 1982.

What to do on a “summer day” in the middle of winter
If you catch an unusually warm spell by the sea, plan your day like a soft shoulder-season escape: a long promenade walk, viewpoints, a sunny café break, and a short beach session. Keep it flexible—conditions can change quickly. Check the forecast, use sun protection, and swim only where it’s safe and permitted.
Comfort tip
Evenings can feel much cooler—pack an extra layer.
Safety tip
Warm air doesn’t always mean warm water—enter gradually and stay cautious.
1-day itinerary (flexible, weather-first)
Morning: seaside stroll and a light breakfast. Midday: take shade breaks—sun can be surprisingly strong. Afternoon: beach time and, if conditions are safe, a short swim. Evening: dinner in town and a walk with a warmer layer ready for cooler temperatures.
2-day itinerary (sea + city balance)
Day 1: go full coastal—beach, promenade, viewpoints, and a relaxed pace. Day 2: go urban—museums, squares, pedestrian streets (especially helpful if wind or clouds arrive). Keep your plan adaptable: warm spells can flip to cooler air or rain.
How to get there (broad overview)
Fly into a major airport in your chosen region, then continue by train, bus, or a private transfer to the coast. During unusual weather swings, it helps to keep rescheduling options and check local alerts for wind, rain, and sea conditions.
FAQ — Spain’s unusual winter warmth
What does a “winter heatwave” mean?
It’s a period of temperatures well above the seasonal norm lasting several days, sometimes making winter feel like spring or summer.
Why can high pressure bring unusual warmth?
High pressure often means clear skies and stable air, which allows stronger daytime heating and can channel warm air into the region.
Is it safe to sunbathe in winter?
Usually yes, but UV can still be strong on clear days—use sunscreen and take shade breaks.
Can it cool down quickly after a warm spell?
Yes. Weather can flip to cooler air, wind, or rain—pack layers and keep plans flexible.
How should I dress for a warm winter on the coast?
Light layers for daytime, plus a warmer layer for evenings when temperatures often drop.
Do I still need sunscreen?
Yes. Clear skies can mean notable UV exposure, especially near the sea.
Why is climate change mentioned in this context?
Because unusual extremes are becoming more frequent and intense, and warm spells are often discussed as part of this broader trend.
Where can I check reliable local forecasts?
Use trusted forecast sources and local alerts, especially before sea activities or mountain trips.
What if the weather turns bad during my trip?
Keep a “Plan B”: museums, old-town walks, cafés, and indoor spots that don’t depend on perfect beach conditions.
Can I swim if it’s 20–30°C outside?
It depends on sea temperature, wind, and currents. Warm air doesn’t always mean warm water—enter gradually and stay cautious.
How do I reduce the risk of overheating?
Hydrate, take shade breaks, use sunscreen, and pay extra attention to children and older travelers around midday.
Can extreme weather affect transport?
Sometimes—especially with wind or rain. Check airline and local transport updates if conditions change.
Why are mountains cooler than lowlands?
Altitude, wind, and cloud patterns usually keep mountain areas cooler, even when the lowlands are unusually warm.
Why do clear skies make it feel warmer?
With fewer clouds, more solar radiation reaches the ground, boosting daytime heating.
Where can I find more travel news and guides?
Follow updates on the site and pick destinations with good “indoor alternatives” in case the weather shifts.
