For a summer trip to Карнак, lightweight clothing is essential, but don’t forget a light sweater for cooler evenings.

A sun hat and sunscreen are also useful, as the coastal breeze can make the sun feel less intense than it is.

In winter, Карнак’s mild climate means you won’t need heavy winter gear, but layers are key. A waterproof jacket is practical for November through February, when rain is more frequent. Comfortable walking shoes are a must year-round, especially if you plan to explore the megalithic sites or coastal paths.

For spring and autumn visits, packing versatile layers will help you adapt to Карнак’s changeable weather. In April or October, mornings can be cool, while afternoons warm up to 15–17 °C. A scarf and a light jacket are handy for breezy days, particularly near the coast.
