rigger 47 Posted November 8, 2016 Share Posted November 8, 2016 Local weather conditions can play a big part in actual recorded tide levels. Global warming probably does play a part but probably a lot less than most people think.Tidal predictions for Auckland have remained pretty constant at around 12ft (3.6m) over the the last fifty years but in recent years we have seen predicted 3.6m tides go as high as 3.85 due to local weather, however large tides are nothing new. The 1930's saw a tide go over 13ft (4.00m). Two roads that are most susceptible to flooding, Tamaki Drive and the Northwestern motorway between Waterview and Patiki Rd both suffered the same problem and that was the roads sinking into the mudflats both roads have dropped around on metre since built. The Councils are also allowing people to built in flood prone areas so these flooding problems are becoming more prevalent. for what it is worth 1936 - 3.99m - 13ft 1&3/32" 2011 - 4.12m - there was a deep depression coinciding with a spring tide Quote Link to post Share on other sites
