The Mediterranean climate is one of the biggest draws to this coast, but "sunny" doesn't tell you much on its own. Here's what the official climate data actually shows for Alicante, which sits at the heart of the southern Costa Blanca.
Average temperatures through the year
According to AEMET, Spain's state meteorological agency, Alicante's standard climate values show mean monthly temperatures ranging from around 11-12°C in January to the high 20s in July and August, with daytime highs regularly in the low 30s°C at the height of summer and rarely dropping below the mid-teens even in the coolest winter months. Rainfall is concentrated in short, sometimes intense spells rather than spread evenly across the year — autumn in particular can bring heavier downpours than people expect from a "dry" climate.
What this means season by season
- Winter (Dec-Feb): Mild by UK and Belgian standards — daytime temperatures commonly in the mid-teens°C — but evenings can feel properly cold indoors if a property isn't well insulated or heated, since many local homes are built with summer heat in mind rather than winter cold.
- Spring (Mar-May): Generally considered the most comfortable stretch — warming steadily, long daylight hours, before the peak summer heat arrives.
- Summer (Jun-Aug): Consistently hot, often 30°C+ in the day through July and August. This is when good air conditioning and shade genuinely matter, particularly for anyone not used to sustained heat.
- Autumn (Sep-Nov): Still warm into September and October, but this is also when the region's occasional heavy rain events are most likely — worth knowing if you're planning outdoor moving-in logistics for this period.
What this means if you're planning a viewing trip or a move
Many people visit in the shoulder seasons (spring or early autumn) specifically to see the area outside of peak summer heat and peak tourist season, which also tends to mean better availability for property viewings and removals bookings.
