Benidorm May — the deeper picture
May's UV index climbs to 8 — the same as July on the Costa Blanca — despite the milder air temperature. It catches British visitors out every year: cooler feeling but the same burn risk as high summer. Any exposed skin gets sun cream, and midday shade is now genuinely necessary.
Compared to the UK: UK sits at 14–17°C. Benidorm delivers proper summer weather a full month before the UK does.
