Althea Beach

It is characterized by its smooth sandy surface, which is occasionally interspersed with pebbles, and the clear, calm waters that surround it. The beach is somewhat secluded due to a staircase that provides the only access to it which, in combination with the serene environment it offers, contributes to its appeal.

Despite being considered unorganized, the beach is well-regarded for its natural beauty. It features a picturesque vegetated background and offers a captivating view of the small islet of Duni.

Althea Beach: Weather Today

📅 Wednesday, July 29, 2026
It is a challenging day to visit Althea Beach, primarily due to the strong winds sweeping across the shoreline. While the sky remains clear and sunny, the intense wind makes lounging on the sand uncomfortable as it kicks up loose grains. With a maximum air temperature of 32.3 °C and a sea temperature of 27.1 °C, the water is inviting and perfectly suitable for swimming, though you should exercise caution given the choppy surface conditions and moderate waves. The sun is exceptionally strong today with a UV Index of 8.25, so ensure you apply plenty of sunscreen and seek shade frequently. If you can manage the blustery environment, the water provides a refreshing escape from the heat, but consider whether the wind will hinder your relaxation before heading out.
