Differences between regions exist, but they are not stark. The northern Adriatic tends to be a bit cooler than in Dalmatia.<\/p>\n<p>Sea temperatures in September depend on how hot the weather is. If there&#8217;s a heatwave outside, the temperatures are very close to July and August. Sea temperatures drop towards the end of September.<\/p>\n<p>To put some real numbers on it, here is what one morning measurement from <strong><a href=\"https:\/\/meteo.hr\/podaci_e.php?section=podaci_vrijeme&amp;param=more_e\" target=\"_blank\" rel=\"noopener noreferrer\">DHMZ<\/a><\/strong> (Croatian Meteorological and Hydrological Service) said in <strong>early September<\/strong> (during a heatwave that is uncharacteristic for September).<\/p>\n<table class=\"news-table\" style=\"height: 114px;\" width=\"837\">\n<thead>\n<tr>\n<th style=\"text-align: center;\">Station<\/th>\n<th style=\"text-align: center;\">Sea temperature <strong>(\u00b0C)<\/strong><\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"text-align: center;\">Pula<\/td>\n<td style=\"text-align: center;\"><strong>26,5<\/strong><\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\">Rab<\/td>\n<td style=\"text-align: center;\"><strong>25,4<\/strong><\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\">Zadar<\/td>\n<td style=\"text-align: center;\"><strong>25,7<\/strong><\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\">Split<\/td>\n<td style=\"text-align: center;\"><strong>26,0<\/strong><\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\">Dubrovnik<\/td>\n<td style=\"text-align: center;\"><strong>26,8<\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<div><\/div>\n<div class=\"custom-highlight-block\">Enclosed bays can be several degrees warmer than the open sea.

Most people agree that the sea becomes somewhat comfortable for swimming once it passes 20\u00b0C (some put this number at 22 \u00b0C). The range between <strong>22 and 26\u00b0C<\/strong> is the most <strong>ideal<\/strong>. The sea warms up slowly over summer, so it also <strong>loses heat slowly<\/strong> once the days get shorter. You&#8217;ll notice the air already cools in the evenings in September, but the sea temperatures don&#8217;t change as quickly.<\/p>\n<h2><strong>A few tips for beach days in September<\/strong><\/h2>\n<ul>\n<li>Make the most of mornings and afternoons, when the sun is warm and beaches are nearly empty.<\/li>\n<li>Do not skip <strong>sun protection<\/strong>, the UV index is still strong in early autumn.<\/li>\n<li>Pack a light jacket for the evening.
