the water temperature: The coldest time of year is March at around 6-7 degrees rising slowly to reach 13-14 degrees by end of May and 14-15 degrees by the end of July. The sea temperature stabilizes and doesn’t start to drop again until November and it falls slowly to about 10 degrees by January. Cooling is more rapid after that until it reaches its low in March.
diving depths: range mostly between 15-35m although there are plenty of opportunities if you wish to peek over into the big blue abyss.
underwater visibility: is often spectacular, reaching up to 30 metres when sea temperatures are at their coldest, but visibility rarely drops below 8-10 m in the confined sea-lochs during a plankton bloom, usually induced by heat and sunlight. Visibility on the exposed tidal shores is most often 15 m+ or above.
tidal currents: Many of the sites are non-tidal, although there are a couple of wrecks where slack tide is required, reasonably reliable, and managed by most divers with a little care. We do have a number of dives that can be dived either on slack or as a gentle drift if preferred.
dive confidently: There is NEVER any pressure to dive any site. The skipper will advise of the dive conditions, but the ultimate choice to dive or not, lies with the individuals and collective group. It is ALWAYS possible to offer a different site with conditions that are in the collective groups 'comfort zone'. It is NEVER an inconvenience or too late to reassess the dive plan.
