For a trip to Касама during the rainy season (November to April), lightweight, quick-drying clothing is essential, along with a sturdy rain jacket and waterproof footwear. Mosquito protection is also important, as standing water can increase insect activity. A compact umbrella may come in handy for sudden downpours, though it’s best to plan outdoor activities for the morning when skies are clearer.

In the dry season (May to October), layers are key. Days are warm, so breathable fabrics work well, but evenings can be cool, especially in June and July, when temperatures drop to +11 °C. A light sweater or jacket will keep you comfortable after sunset. Sun protection—hats, sunglasses, and sunscreen—is a must year-round, as Касама enjoys plenty of sunshine even in the cooler months.
