Yes - it is one of the better months: hot days, little rain and long sunny days. The best months for Costa Blanca on our scoring are July, June, August; months averaging 25°C or more: Jun, Jul, Aug, Sep.
Warm days, with room for hotter spells
Pack mainly for summer: light clothing for the day, sun protection and a light layer for sitting outside late. June's average high makes it well suited to travellers who want reliable warmth rather than cooler walking weather. Days reach 25°C on 75% of occasions, so warmth is the usual pattern, not just a lucky break. Plan more active outings for the morning and leave room for shade or a slower pace at midday. Nights are generally mild, but the cooler end of the range falls to around 16°C or below, so leaving every extra layer at home would be optimistic.
Good swimming weather and little rain
The sea averages 22°C, putting June on the swimming side of the line, though it will not feel like bathwater. The year-to-year range is 21°C to 23°C, so your comfort on entry may vary. Rain is unlikely to dominate a holiday: there are about 2 rainy days during the month, making a flexible outdoor plan more useful than a packed wet-weather itinerary. Sunshine averages about 10.6 hours a day, giving plenty of scope to enjoy the coast outside the hottest part of the day. This combination suits travellers who want swimming and time outdoors, provided they are happy to seek shade when the heat builds.
