Cilaos enjoys a unique tropical highland climate in Reunion Island. Located at an altitude of 1,200 meters / 3,937 feet in a volcanic cirque, the town benefits from cooler temperatures than the coast, with marked variations between the dry and wet seasons, influenced by trade winds and the mountainous terrain.

Cilaos Town Center: The most protected area of the cirque with moderate temperatures
Cilaos Highlands: Cooler sector towards hiking trails, frequent fog
Route des Makes: Access zone with climatic variations depending on altitude

The 1,200-meter / 3,937-foot altitude creates a unique microclimate with temperatures 8-10°C / 14-18°F cooler than at the seaside. Altitude variations within the cirque (from 1,000 to 2,000 meters / 3,280 to 6,562 feet) generate very different weather conditions over short distances, with frequent cloud and fog formation at higher elevations.
