Water temperature drops to around 11 degrees Celsius in winter, so a drysuit or thick wetsuit is worth arranging in advance through the on-site dive shop. Because visibility is variable, ask the guide on the day about current conditions before deciding whether to dive shallow or push toward the 26-metre range.
