Weather in Kastellorizo

The climate on the island of Kastellorizo can be described as typical Mediterranean, with hot, dry summers and mild but humid winters. The weather here is conducive to relaxation for most of the year, although the choice of season depends on the purpose of your trip.

Summer is the ideal time for a beach holiday. In July and August, the average temperature holds around 27°C, with daytime highs often rising above 30°C. Rain is practically unheard of during these months; for instance, July typically sees only one rainy day on average.

The shoulder season and spring are excellent for excursions and long walks. In September, the water is still warm, and the air warms up to a comfortable 24°C. May and June also delight visitors with sunny weather, temperatures ranging from 19°C to 23°C, and minimal rainfall.

In winter, tourism on the island quiets down. January and February are the coolest months with an average temperature of about 10°C. This is also the wettest period of the year: in January, the number of rainy days can reach 16, so travellers should be prepared for changeable weather.

Kastellorizo, also known as Megisti, is a tiny yet incredibly picturesque island serving as the easternmost point of Greece. Located at the very edge of Europe, just a few kilometres from the Turkish coast, it stands apart from noisy tourist routes, preserving an atmosphere of genuine seclusion and tranquillity.

The island's hallmark is its unique architecture, which differs noticeably from the familiar Cycladic style. Instead of white cubes, travellers are welcomed by elegant neoclassical mansions with tiled roofs and tall windows. The facades of the houses, painted in vibrant ochre, terracotta, and blue colours, are built like an amphitheatre around a deep natural harbour, creating the impression of a colourful theatrical set.

This corner of the Mediterranean is perfect for history enthusiasts and those seeking a leisurely holiday. There is almost no car traffic here, and the rhythm of life has remained unchanged for decades. Guests of the island can explore narrow cobbled streets, climb to the ruins of the Knights of St John castle for panoramic views, or take a boat to the famous Blue Cave — one of the most impressive natural grottos in Greece.

The climate in Kastellorizo is distinguished by pronounced seasonality, typical of the Mediterranean: hot summers and mild, wet winters prevail here. The coldest period of the year is January and February, when the average air temperature is around +9.5°C...+10°C. During this time, night-time readings may drop to +6.7°C, although severe frosts are not characteristic of the island, and during the day the air often warms up to a comfortable +12...+13°C.

Summer months bring genuine warmth and dry weather. July and August are the peak of the heat, when the average temperature reaches +26.8°C, and daytime maximums regularly exceed the +30°C mark. Notably, even nights at the height of summer remain very warm, with temperatures around +23°C, creating ideal conditions for long evening walks by the sea, although it requires getting used to the constant heat.

The shoulder season on the island offers the most pleasant conditions for those who prefer milder weather. In May and October, a "golden mean" is established: average temperatures hold at the level of +19...+20°C. In these months, the difference between daytime warmth (up to +23°C) and night-time freshness (around +16°C) is felt more strongly than in summer, ensuring a comfortable balance for excursions and outdoor recreation.

Precipitation on the island of Kastellorizo is distributed unevenly throughout the year, following a typical Mediterranean scenario. The wettest period falls during the winter months. January and December lead in the frequency of rainfall: during this time, statistics record from 14 to 16 rainy days per month, so travellers planning a visit in winter should carry an umbrella or raincoat.

Summer, conversely, is characterised by a distinct dry season. July and August are the driest months of the year, when rainfall approaches zero, and the probability of rain is minimal (only 1–3 days with precipitation per month). During this period, the sky above the island remains practically cloudless, guaranteeing ideal conditions for a beach holiday.

Spring and autumn serve as a comfortable transition between seasons. In April, May, and October, rains occur less frequently than in winter (on average about 5–6 wet days), and they are usually short-lived. By November, the amount of precipitation begins to gradually increase, preparing nature for the winter season.

When packing for Kastellorizo, it is important to consider the seasonality of this picturesque corner. Summer brings hot and dry weather, so your luggage should primarily consist of light clothing made from natural fabrics such as linen and cotton. Do not forget swimwear, sunscreen with a high protection factor, sunglasses, and a hat to protect against the bright Mediterranean sun during long walks.

If your journey is planned for the period from November to March, it is worth preparing for cooler days and frequent rainfall. At this time of year, a waterproof windbreaker or raincoat will be useful, as well as a warm sweater or fleece jacket for evening promenades by the sea. In spring and autumn, the weather can be changeable, so it is better to use the principle of layering in your clothing to easily adapt to temperature changes throughout the day.

Regardless of the time of year, pay special attention to your choice of footwear. The local terrain and cobbled streets require comfort, so comfortable trainers or flat, non-slip sandals will be much more practical than formal shoes. It is also recommended to bring a small backpack for water and necessary essentials during excursions around the island.
