The Arabian or Persian Gulf is recognized as one of the warmest estuaries globally. The sea surface temperature (SST) has been utilized in several studies to gauge the global warming associated with climate change. In the current investigation we present detailed in situ SST measurements for five consecutive years (2016, 2017, 2018, 2019, 2020) in the northwest of the Gulf, specifically in Kuwait Bay. Results of data analyses were compared with the historical records for the region, revealing that the SST reached an extreme level never previously recorded either in the Gulf. The extreme SST in Kuwait Bay reached 37.6 °C, recorded by the offshore station KISR01 located in the middle of the Bay. The event was associated with heatwave, neap tides, and an extended period of Kous winds which are characterized by high humidity levels and accompanied by large-scale intermittent fish kill incidents that extended the full length of the Kuwait coastline. Several fish kill incidents were reported also at the northern edge of the Gulf along Shatt Al Arab stretch in Iraq. The species found dead during the incident varied considerably, unlike those found in the frequent summer incidents. The records presented in this study may provide evidence to the effects of global warming, aid further research, and encourage the concerned international government bodies to deliver urgent environmental policies.

阿拉伯或波斯湾被公认为全球最温暖的河口之一。海面温度（SST）已用于多项研究中，以评估与气候变化有关的全球变暖。在当前的调查中，我们提供了墨西哥湾西北部，特别是科威特湾连续五年（2016、2017、2018、2019、2020年）的详细原位SST测量结果。将数据分析的结果与该地区的历史记录进行了比较，发现海表温度达到了海湾地区从未有过的极端水平。位于海湾中部的近海站KISR01记录到，科威特湾的极端SST达到37.6°C。该事件与热浪，潮汐，一段高湿度的高风，伴随着大规模的间歇性鱼类致死事件，延长了科威特海岸线的全长。据报道，在伊拉克北部沙特阿拉伯河沿岸的北部边缘也发生了几起鱼类死亡事件。与在夏季频繁发生的事件不同，在事件发生期间发现的死亡物种差异很大。本研究报告提供的记录可能为全球变暖的影响提供证据，有助于进一步研究，并鼓励有关的国际政府机构提出紧急的环境政策。据报道，在伊拉克北部沙特阿拉伯河沿岸的北部边缘也发生了几起鱼类死亡事件。与在夏季频繁发生的事件不同，在事件发生期间发现的死亡物种差异很大。本研究报告提供的记录可能为全球变暖的影响提供证据，有助于进一步研究，并鼓励有关的国际政府机构提出紧急的环境政策。据报道，在伊拉克北部沙特阿拉伯河沿岸的北部边缘也发生了几起鱼类死亡事件。与在夏季频繁发生的事件不同，在事件发生期间发现的死亡物种差异很大。本研究报告提供的记录可能为全球变暖的影响提供证据，有助于进一步研究，并鼓励有关的国际政府机构提出紧急的环境政策。
