Knowledge of sea surface temperature (SST) behaviour is vital for long-term climate scenarios. This study highlights essential outcomes about the distinguishable and unsurprising warming of the SST along the southern border of the Levantine Basin. The analysis is based on monthly SST data for the period 1948–2018. The southern Levantine Basin has undergone SST increase, during the last 71 years. In this study, a consistent warming trend has been found for the analysed SST data series, with a rate of 0.04°C/a, i.e., 0.4°C/(10 a). From 1975 to 1991 the mean annual SST was 17.1°C, and this increased to be 19.2°C, over the period 2002–2018. Results revealed two opposite trends of variability: a decreasing trend (−0.06°C/a) over the period 1975–1991, and an increasing trend (0.2°C/a) from 2002 to 2018. Over the period 1948–2018, positive mean annual SST anomalies had an average of 1.8°C, and negative anomalies had an average of −1.1°C. The lowest SST total increase was found from January to April, with values about 0.03°C, while the highest warming appeared from June to September. The driving mechanisms behind the SST changes need to be more investigated, to understand the future trends and impacts of climate change in the Levantine Basin.

了解海面温度（SST）行为对于长期气候情景至关重要。这项研究突出了沿黎凡特盆地南部边界的海表温度明显升高和令人吃惊的变暖的基本结果。该分析基于1948-2018年期间的每月SST数据。在过去的71年中，南部黎凡特盆地经历了海温上升。在这项研究中，对于所分析的SST数据系列，发现了一致的变暖趋势，其升温速率为0.04°C / a，即0.4°C /（10 a）。从1975年到1991年，在2002-2018年期间，平均年SST为17.1°C，并且上升到19.2°C。结果显示出两个相反的变化趋势：1975-1991年期间下降趋势（-0.06°C / a）和2002-2018年期间上升趋势（0.2°C / a）。1948-2018年期间，SST的年平均正异常平均值为1.8°C，负的平均异常平均值为-1.1°C。1月至4月，SST的总增幅最低，约为0.03°C，而6月至9月则是最高的增温。需要进一步研究SST变化背后的驱动机制，以了解黎凡特盆地的未来趋势和气候变化的影响。
