Understanding the Calpe climate makes it much easier to plan the kind of trip you actually want on the Costa Blanca. While Calpe enjoys warm sunshine for most of the year, each season has its own feel, from lively summer days to quieter, milder winters.
In this guide, you’ll find a clear breakdown of what to expect month by month. From average temperatures and rainfall to sea conditions and the best times for different activities, it’s designed to help you decide when Calpe suits you best.
Calpe Climate Overview
Calpe has a classic Mediterranean climate, with hot, dry summers and mild winters that are generally short and comfortable. In January, daytime temperatures usually sit around 16 °C, while August often reaches around 30 °C. Winter evenings can drop to around 7 to 10 °C, whereas summer nights tend to stay warm at 20 to 24 °C.
Rainfall is relatively low across the year, averaging between 440 and 500 mm. July and August are typically very dry, while September and October can bring heavier showers, sometimes around 70 to 80 mm, often in short bursts rather than long periods of rain.
Sunshine is one of Calpe’s biggest draws, with around 2,800 to 3,000 hours annually. In summer you can expect up to 10 or 11 hours of daylight, while winter still offers around 5 to 6 hours, which keeps the days bright and usable.
Sea temperatures follow a similar pattern. In winter, the water sits around 14 to 16 °C, rising steadily to 25 or 26 °C by late summer. That means swimming is comfortable for much of the year, especially from late spring through early autumn.
Winter in Calpe (December–February)
Winter in Calpe is mild, especially compared to much of northern Europe. Daytime temperatures usually range from 15 to 17 °C, with evenings cooling to around 6 to 10 °C. A light jacket is generally enough during the day, with an extra layer after sunset.
Rainfall is moderate rather than heavy. December is typically the wettest month at around 50 to 55 mm, while January and February average closer to 30 to 35 mm. Snow is extremely rare, and frost is uncommon.
Sea temperatures sit around 14 to 16 °C, and you can expect roughly 5 to 6 hours of sunshine per day. It’s a quieter time of year, ideal for walking, sightseeing, and enjoying the coastline without the summer crowds.
Spring in Calpe (March–May)
Spring in Calpe brings warmer days and longer evenings. Daytime temperatures rise from around 18 °C in March to 23 or 24 °C by May, while nights become milder, moving from 9 or 10 °C to around 13 or 14 °C.
Rainfall is generally light and short-lived. March and April see around 35 to 40 mm, with May often a little drier at 20 to 30 mm, usually falling in brief showers rather than long periods of rain.
Daylight increases quickly through spring. March brings around 12 hours of daylight, rising to roughly 14 to 15 hours by late May. The sea begins to warm too, starting at around 15 °C and reaching 19 or 20 °C by the end of spring.
Spring temperatures are also well suited to more active coastal excursions, including boat trips to hidden coves and quieter swimming spots before peak season begins.

Summer in Calpe (June–August)
Summer in Calpe is hot, dry, and reliably sunny. Daytime temperatures rise from the mid twenties in June to around 30 °C by August, while nights stay warm at roughly 17 to 23 °C.
Rain is rare during these months. July is usually very dry, and August may see a brief shower, but long spells of sunshine are the norm. You can expect around 10 to 11 hours of bright sun each day, with long daylight hours stretching well into the evening.
The sea warms from about 22 °C in June to 25 or 26 °C by August, making it perfect for swimming.
These are also the best months for the catamaran cruises with swim stops around the Peñón de Ifach, when the water is warm and conditions are typically calm.
Beaches in Calpe, including Playa de la Fossa and Arenal Bol, are at their busiest during this period, with calm, warm water ideal for families and water sports.
It’s the liveliest time of year, with busy promenades, beach days, sailing trips, and summer events shaping the atmosphere across town.
Long summer evenings also lend themselves well to sunset boat tours from Puerto Calpe, when the coastline takes on a softer light and the sea remains calm into the evening.

Autumn in Calpe (September–November)
September still feels like summer in Calpe. Daytime temperatures average between 25 and 28 °C, with warm evenings around 19 to 22 °C. The sea remains at its warmest, around 25 to 26 °C, and sunshine is still generous, often eight hours or more per day. Rain can occur, but it’s usually limited to a few short-lived showers.
By October, the heat begins to ease. Highs settle around 22 to 24 °C, with cooler nights between 14 and 16 °C. Rainfall can increase slightly, sometimes arriving in heavier bursts rather than steady drizzle.
November feels noticeably calmer and cooler. Daytime temperatures drop to around 17 to 20 °C, with evenings closer to 10 to 12 °C. Rain becomes more frequent, though often light, and the sea gradually cools from the low twenties to around 18 or 19 °C by late autumn.
For many visitors, early autumn offers a comfortable balance of warm sea, softer sunshine, and fewer crowds along the coast.

Final Thoughts: Choosing the Best Time to Visit Calpe
Calpe’s climate is one of its biggest strengths. Sunshine is reliable, winters are mild, and the seasons shift gradually rather than dramatically.
Summer suits those planning beach days and long evenings by the sea. Spring and early autumn are often more comfortable for walking, exploring, and enjoying the coastline without peak season crowds. Winter remains pleasant and quieter, making it a good time for hiking and sightseeing.
The best time to visit depends on what you want from your trip. For swimming and beach-focused holidays, June through September works well. For cooler temperatures and a slower pace, March to May and October to November are often a better fit.
At any time of year, Calpe offers steady weather and a relaxed coastal setting that makes both short visits and longer stays easy to enjoy.
