An unusual alignment of the sun, moon and Earth means the gravitational pull on oceans will be higher than usual five more times this year. The first, on 22 January, caused no damage.
A department spokeswoman said the tides should not cause any significant problems for the island, and its staff would monitor them as and when they happened.
'In 2014 there were nine tides predicted at 10m or more. In 2015 there are 24 such high tides, with the highest tides of 10.3m on 21 February, 22 March and 29 September.
'Barometric pressure also affects the height of the tide, if the pressure is low the tide will be higher. Wind speed and direction is also a prime factor on how such tides will affect the island's coasts.
'The details of all high spring tides are noted by the department's staff as soon as tide tables are issued each year.'
