Best Month to Visit Kos

January in Kos is a mild winter, often sunny but with the expected chill in the air. Average temperatures hover around 56°F (13°C) during the day, dropping to 47°F (8.5°C) at night. The rainfall is significant, around 5.6 inches (143 millimetres). Kos rarely gets snow. January is considered low season with fewer tourists, thus resulting in lower hotel prices.

When we move into February, the weather remains fairly similar to January. Average day temperatures sit comfortably at 57°F (14°C) and fall to 47°F (8.5°C) at night. Rainfall sees a slight decrease to around 4.3 inches (110 millimetres). Again, February is ideal for enjoying off-peak hotel pricing, as there are typically no major events happening.

March begins to show a few signs of the impending spring. Daytime average temperatures increase to around 61°F (16°C) and fall to 49°F (9.5°C) after sunset. Rainfall continues to drop as we see averages around 3.2 inches (80 millimetres). The island begins to come to life with the local Almond Blossom Festival, bringing an authentic Greek experience with lower hotel rates.

Those unfazed by the heat may find July to be the best time to visit Kos. With temperatures hitting an average high of 88°F (31°C) and nights at 73°F (23°C), this is prime beach weather. Rain is virtually non-existent in July. Remember that hotel prices remain at the height of their range.

August keeps the July's weather pattern stable, with hot days averaging about 88°F (31°C) and nights at 73°F (23°C). You can expect no significant rainfall in August. Kos's annual Wine Festival attracts oenophiles this month. Keep in mind that hotel prices remain high.

September starts to mellow out the summer heat with daily averages down slightly to 82°F (28°C) and night temperatures around 68°F (20°C). Rainfall remains low at 0.3 inches (8 millimetres). Hotel prices start to reduce as the tourist crowd thins, making this a great time to experience the Olive Oil Festival celebrated in the local villages.

October brings in the autumn weather. However, it's still pretty warm, with average daily temperatures about 73°F (23°C) and nights cooling to 61°F (16°C). There's a slight increase in rainfall to 1.9 inches (48 millimetres). Hotel prices continue to fall, making it an economical choice.

November experiences a further drop in temperatures with 66°F (19°C) during the day and 54°F (12°C) at night. Rainfall levels increase to 3.5 inches (90 millimetres). There are fewer crowds around this time, leading to even lower hotel prices. This is a quiet month, with no notable events.

December carries the tranquillity of November into the holiday season. Temperatures range from an average of 59°F (15°C) during the day to 50°F (10°C) at night. Rainfall peaks at around 5.9 inches (150 millimetres). Hotels offer competitive prices to make for a delightful and affordable holiday escape.

Best Time to Visit Kos

From our month-by-month breakdown, it’s clear that the best time to visit Kos is subjective and depends on what kind of holiday you're after. For those who fancy the beach, consider the warm months of June through August.

However, if you prefer a cultural experience full of authentic Greek events, then visit during spring (March to May) or autumn (September to November). And, for the best deals at hotels, travelling during the winter months might be worth braving the colder Kos weather and heavier rainfall.

There’s no 'one size fits all' when it comes to identifying the best time to visit Kos. The island's vibrant festivals, historical highlights, and stunning coastlines have something to offer to all sorts of travellers year-round.
