🏖️ Costa Blanca Weather by Town
Weather in Alicante
Alicante is one of the sunniest spots on the Costa Blanca, with over 320 sunny days a year. Summers are hot and dry, while winters are mild and rarely dip below 10°C. Being coastal, the sea breeze helps cool things down even in July and August.
What to expect: A reliable beach climate with very little rain and loads of sun.
Weather in Benidorm
Benidorm’s position between two mountains gives it a unique microclimate — warmer winters and slightly more humid summers than surrounding areas. It’s one of the warmest spots in winter, often reaching 18–20°C on sunny days.
Locals say: Benidorm’s climate is one reason it’s so popular year-round.
Weather in Calpe
Calpe enjoys typical Costa Blanca weather — hot summers and pleasant winters. Its two beaches and the iconic Peñón de Ifach mean you can usually find a sunny or sheltered spot year-round.
Our tip: Calpe is slightly less breezy than some nearby towns, making it ideal for early spring sunbathing.
Weather in Jávea
Jávea (Xàbia) sits in a small bay with a unique layout that creates slightly more humid conditions in summer. It also sees slightly more rainfall than towns to the south, especially in late autumn.
What to expect: A lush, green feel thanks to the extra moisture — and beautiful hiking in spring.
Weather in Dénia
Denia gets more wind than other towns thanks to its northern exposure and proximity to Montgó mountain. It’s also one of the greener areas on the coast and sees more rainfall in autumn.
Locals say: Denia is ideal if you like active holidays — good breezes for sailing and wind sports.
Weather in Altea
Altea offers classic Costa Blanca weather, with a peaceful seaside vibe. Summers are dry and hot, and winters remain sunny and pleasant. It gets slightly cooler at night due to its hillside layout.
Our tip: Bring a light jacket for the evenings, even in spring.
Weather in Torrevieja
Located in the south, Torrevieja enjoys some of the warmest sea temperatures along the coast. It also has a dry climate, influenced by the nearby salt lakes, and plenty of sunshine.
What to expect: Warm, sunny days well into autumn — and ideal conditions for year-round outdoor living.
Weather in Moraira
Moraira is nestled between hills and the sea, offering a calm and sunny climate with slightly less wind. It’s a favourite among expats for its pleasant year-round temperatures.
Locals say: Moraira’s microclimate keeps it cooler in summer and warmer in winter — just right.
Inland & Hilltop Towns (e.g., Benissa, Teulada, La Nucia)
These inland spots sit slightly higher up, which means cooler nights — especially in winter — and a bit more variation in temperature between day and night. They’re great if you prefer a slightly fresher climate without straying far from the coast.
Our tip: Expect fantastic views and quieter surroundings — perfect for spring and autumn stays.
Southern Edge (Pilar de la Horadada, Guardamar, Orihuela Costa)
In the far south, these towns enjoy some of the mildest winters on the Costa Blanca. Sea temperatures tend to stay warmer for longer into autumn, and the area enjoys a drier climate overall.
What to expect: A gentle winter sun destination with less wind and warmer sea.
