The best time to go to Cos is during the shoulder seasons, specifically May, June, and September, to enjoy pleasant weather without the peak summer crowds.During these months, the weather is typically warm and sunny, with average temperatures ranging from 20°C to 25°C, making it ideal for exploring the natural beauty of the region. You'll find the popular hiking trails, such as those around the Gorges du Tarn, less crowded, allowing for a more serene experience. The local markets are also in full swing, offering fresh produce and regional specialities.Families travelling with children will particularly appreciate late May and early June, or early September. The temperatures are comfortable for outdoor activities like kayaking on the Lot River or visiting the animal park in Gramat, but the larger crowds of the school holidays in July and August are avoided. Accommodation prices also tend to be more favourable outside of the absolute peak season.For couples looking for a romantic getaway, September is an excellent choice. The vineyards are preparing for harvest, offering tasting opportunities, and the evenings are still mild enough for al fresco dining in the charming villages like Saint-Cirq-Lapopie.
