The morning was partly cloudy with near calm conditions and a light NW breeze at the swim start. Visibility was excellent and the outline of the hotels in Salthill could be seen across the bay. The main concern was some sightings of Lions Mane jellyfish but fortunately, there were no major incidents reported.
Low tide in Aughinish at 6.41am meant that the tide had turned and was filling by the time the first wave of swimmers entered the water at 8.30am. The tide was coming in for the duration of the swim but as these were neap tides, the current flow was not significant. High tide in Salthill was at 1.12pm which allowed the swimmers to swim right into the steps for the finish and a great reception from the large crowd gathered at Blackrock.
The wind dropped in the middle section of the bay with near calm conditions which were as good as have been experienced in recent years. In the afternoon, due to the sunny weather, a strong sea breeze kicked in. This meant that swimmers that were in the water from 1.00pm onwards saw a big increase in wind speed (12 Knots) and wave height.
141 swimmers crossed Galway Bay – (55 solo swimmers, 29 relay teams (86 relay team swimmers).
