Long wetsuits needed all year round - although people were seen in shorties some times. Air around 30°C in the summer, down to 15°C in the winter. The water is pretty cold, around 10-15°C in the summer and 13-17°C in the winter. The longer the South Easter (prevailing summer wind) blows, the colder the surface water gets. Doesn't matter much in summer though.
The winds is a bit gustier with SE. In the summer, the wind is mostly S to SE, but of which are pretty exactly sideshore; this is the perfect wind (called Cape Dr.) and can get very strong at times - up to 40 knots. The wind tends to pick up in the mornings and get stronger. So if super strong winds are predicted, get there early! NW is mostly a bad weather or winter wind. Less reliable, but often associated with big waves.
From Cape Town drive south towards Simon's Town and keep driving south following signs to Cape Hope. You need to turn right, about 0.2 miles before a round about to get to Cape Point. Follow that road almost to its end and you will pass by the launch, just where the waves are the nicest.
