Alicante
Costa Blanca with an old town, a castle on a rock, and reliable late-summer sea. Cheaper than Mallorca, similar hours of sun, one of the easiest cheap-flights from northern Europe.
Sunny every day, no rain, no heat spikes. The week to book.
Days 1–5 are usually reliable, 6–10 drift, 11–14 are the model guessing. Check again the day before you fly — more on what this can and can't do.
When to go
From the 2026 climate study, not the live forecast.Structural odds, not a verdict — the live forecast can still surprise either way.
Sea crosses 22°C in late June, peaks at 28°C in August, still 24°C through October. Old town (El Barrio) climbs to Santa Bárbara castle; Postiguet beach is the main strip but the better swimming is at Playa San Juan. The Costa Blanca summer is among the most stable Mediterranean weather you can book — heat-cliff days above 35°C still happen but rare.
Cheapest return we found: 14–21 Sept · 1+ stops. Live search on Kiwi.
Common questions about Alicante
When is the best time to visit Alicante?
May–July and September–October are when we'd go. Skip December–February: a sea still too cold for most people. The live forecast on this page shows what the next two weeks look like.
Is Alicante worth visiting in June?
Yes. June sits inside the best stretch (May–July and September–October). Once your dates fall within the next two weeks, the forecast above gives you the real picture.
Is Alicante good in December?
We'd go another month: December means a sea still too cold for most people. Locked dates? It still works if you treat the sea as scenery, not swimming.
Dates settling? Compare hotels on Booking and flights on Kiwi — both open with the forecast's best window pre-filled.
