Winds and waves brought tide levels above the highest tides of the year (HAT) and this was particularly evident at Cooktown where a 0.4 m storm surge was recorded on the morning high tide (0.3 m above HAT) on 19 March. Many boats were upturned in the harbour and washed away. Further south storm surges caused the flooding around the northern beach suburbs of Cairns and required the closing of some roads.
