And that\u2019s without including October in the tally and with a wet El Ni\u00f1o winter ahead \u2014 a worrying sign for coastal homes and infrastructure.<\/p>\n<p>Researchers can\u2019t yet project how many more days of flooding we\u2019ll have in 2026 \u2014 but we\u2019re already well ahead of what the National Oceanic and Atmospheric Administration\u2019s models had forecast up to this point.<\/p>\n<p>NOAA oceanographer Karen Kavanaugh said models had predicted three to six flood days between May 2026 and April 2027. Those models took El Ni\u00f1o and sea level rise into account. She said that there have already been nine flood days in that window and added that the 12 flood days so far in the calendar year are \u201cabnormally high.\u201d<\/p>\n<p>The number of days of coastal flooding observed at <a class=\"Link\" href=\"https:\/\/tidesandcurrents.noaa.gov\/stationhome.html?id=9410660\" target=\"_blank\" style=\"text-decoration:none;\" rel=\"nofollow noopener\">NOAA\u2019s tide gauge in San Pedro<\/a> is the highest recorded since observations started being taken in 1923. The previous record was set at nine in 1983, during another El Ni\u00f1o event.<\/p>\n<p>When might we see more flooding?<\/p>\n<p>Kavanaugh couldn\u2019t say with certainty when flooding might occur, but noted that high-risk times ahead coincide with Thanksgiving and Christmas. Around then, the moon will be at its closest point to the Earth. The stronger gravitational pull from the moon causes what are commonly known as king tides, a <a class=\"Link\" href=\"https:\/\/www.coastal.ca.gov\/kingtides\/\" target=\"_blank\" style=\"text-decoration:none;\" rel=\"nofollow noopener\">nonscientific term<\/a> for the highest predicted tides of the year.<\/p>\n<p>In addition to these factors, the wide range of events affecting our tides this year, including storms, climate change, <a class=\"Link\" href=\"https:\/\/laist.com\/news\/climate-environment\/tides-coastal-flooding-el-nino\" target=\"_blank\" style=\"text-decoration:none;\" rel=\"nofollow noopener\">El Ni\u00f1o and related Kelvin waves<\/a>, could very well cause other flooding events or cause the existing ones to become stronger.<\/p>\n<p>Kavanaugh said a combination of factors \u2014 specifically Kelvin waves and astronomical high tides \u2014 was exactly what was responsible for the flooding seen this week.<\/p>\n<p>\u201cThat could happen, perhaps, again in November and December if we have another pulse of a Kelvin wave,\u201d Kavanaugh said.<\/p>\n<p>    <img decoding=\"async\" class=\"Image\" alt=\"A man paddleboards with his dog along a flooded street.\" data-image-size=\"articleImage\" width=\"672\" height=\"448\"  src=\"https:\/\/www.newsbeep.com\/us-ca\/wp-content\/uploads\/2026\/10\/1793419095_16_.jpeg\" loading=\"lazy\"\/><\/p>\n<p>Flooding inundated coastal communities around Southern California this week, including Orange County&#8217;s Sunset Beach.<\/p>\n<p>(<\/p>\n<p>Robert Gauthier<\/p>\n<p>\/<\/p>\n<p>Los Angeles Times via Getty Images<\/p>\n<p>)<\/p>\n<p>How high will the tides be?<\/p>\n<p>Unfortunately, Kavanaugh said, there\u2019s no way to predict the severity of upcoming king tide events at this moment in time.<\/p>\n<p>\u201cBut as we move closer to an event, there are good models that the National Weather Service uses to forecast flooding,\u201d she added. \u201cBut they need it to be within seven days, sometimes shorter timelines.\u201d<\/p>\n<p>      High tide resources<\/p>\n<p>These NOAA resources can help you plan for and monitor high tide events:<\/p>\n<p>How to prepare for high tide conditions<\/p>\n<p>Kavanaugh recommended keeping an eye on National Weather Service reports for the latest information and predictions.
