The Costa Blanca consists of 200 kilometres of coastline belonging to Alicante in the country of Spain. Its name means literally the “White Coast” and it is home to a typical Mediterranean climate with long and hot summers and brief and quite mild winters.
You can expect around 3,000 hours of sunshine per year and an average afternoon temperature in excess of 20°C for most of the year. The temperature is cooled in the summer by sea breezes and the surrounding mountains protect the resort from cold northerly winds in the winter. You can expect up to 325 of sunshine days per year. Summers are very long, hot and dry, while winters are cool to mild, with very scarce precipitation in the course of the whole year. Although there have been extreme weather conditions here, such as flooding and storms, the weather is generally extremely enjoyable the majority of the time.
The topography is mountainous to the north and west, then mostly flat to the south. The white sandy beaches and clear blue waters make it a beautiful destination to holiday in—in summer, the weather is nothing less than spectacular; in winter, pleasant temperatures make a popular escape for people from western and northern Europe. If you’re planning on spending your holiday in the Costa Blanca, you can check the detailed and up-to-date weather forecast before choosing your preferred holiday dates.
When you visit the Costa Blanca in summer, you can expect temperatures to range from average highs of 27°C in June to 32°C in August. Even at night, temperatures in this season are not likely to drop below lows of 17°C. In July and August, they don’t even fall below 20°C, which makes the evenings wonderfully pleasant. August is the warmest month of them all, with an overall average temperature of 29°C. July comes in second, with 27°C on average. Both June and September are 25°C and warm.
This season receives the least rainfall for the whole year, with the driest months being July and August. Those two months both receive no more than 6mm of rainfall in total and have merely one day on which it rains. June is the third driest month of the whole year, receiving only 10mm of rainfall. September, on the other hand, marks the beginning of the wetter part of the year and gets 39mm of precipitation—a number which is still not too high whatsoever.
You can expect between 9 and 12 hours of daily sunshine during this season. September has 9 hours, June and August have 11 hours, and July has 12 hours of sunshine per day.
Sea temperatures are at their highest as well in summer. In August, you can enjoy Mediterranean waters that are 25°C warm on average. The sea is one degree cooler in both July and September. June, the beginning of summer, has the “coolest” water, at an average of 20°C.

In autumn, temperatures start decreasing. While October reaches average highs of 25°C, November is significantly cooler with its average highs of 19°C. The nighttime low temperatures also decrease rapidly throughout this season, from 14°C to 9°C. The overall average temperature falls from 21°C to 16°C in the course of autumn—16°C is still quite warm for this time of year, particularly when considering the temperatures in the UK. Sea temperatures become gradually cooler, too, falling to 18°C in November.
This season is also quite wet with between 4 to 6 days of rain each month. The most rain falls within this season, with November receiving more rain than any other month of the year. A total of 42mm of precipitation is spread out 6 days during November, numbers that shouldn’t worry you at all, as they are still very, very low. Even in autumn, the Costa Blanca is a great destination
The numbers of sunshine hours per day decreases steadily, down to 7 hours in October and 6 hours in November. Once again, this is still amazing weather. When you take into consideration the fact that the region lacks the huge numbers of tourists that come with summer, you realise this is a spectacular place to be in October or November.
In winter, the afternoon temperatures range from 16°C to 17°C and the nighttime temperature from 5°C to 7°C. January, with an average temperature of 11°C, is the coldest month of the year in the Costa Blanca. December and February, both averaging 12°C, are slightly warmer. With these temperatures, swimming in the Mediterranean Sea is out of the question. If you try it, you’ll soon decide otherwise after feeling the chilly water. The sea temperature averages 14°C to 15°C in winter, much too chilly for swimming!
You can expect around 4 or 5 days with rainfall per month in this season. Total rainfall amounts range between 23mm and 25mm this season, which are delightfully low.
The amount of sunshine is at its lowest during the winter season, due to more cloud cover and shorter days. Winter days have between 6 and 7 hours of sunshine hours on average.
In spring, temperatures slowly start rising once again. March is the coolest month with an average temperature of 15°C; May is the warmest with 20°C on average. April finds itself in between those two, with an average of 17°C. Evenings and nights may still be chilly—between 8°C and 13°C—but the afternoons quickly warm up and you’ll be able to enjoy 24°C temperatures in May.
Rainfall, surprisingly, increases throughout spring. March is one of the driest months of them all, receiving only 15mm of rainfall. The month of May is the wettest month in this season, with a total amount of precipitation of 30mm, but then precipitation starts to decrease quite a lot in the lead-up to the hot, dry summer.
Daily sunshine hours begin to increase again and you can expect between 9 and 10 hours of daily sunshine hours in April and May. Sea temperatures also rise again, making their way up to 17°C by the end of the season.
