Check the wind before the mountain
If the tablecloth's out, the cableway's shut
Cape Town's southeaster (the 'Cape Doctor') can gust hard enough to close the cableway and Chapman's Peak, and it drapes cloud over Table Mountain like a tablecloth. Check the wind forecast the night before, and if it's blowing, flip your plan — do Clifton or the False Bay side, which are sheltered.
