Evaporative cooler filled with water, takes 20+ litres. Running the fan/pump on the lowest setting. We had another hot night, temps didn't drop below 24˚C & I had a desk fan running flat out all night for some relief, the evap cooler is more effective, though.
Looking like another warm night, expecting 20˚C.
Must remember that option-k is the shortcut for ˚.
