Sea Temperature is a conventional subject of ocean research, and sea surface temperature (SST) research is the focus in the study of ocean temperature, which is the most valuable ocean hydrological element in the research of oceanographic physics and global climate change. With the observational data of SST from seven Marine Environmental Monitoring Stations (MEMS) along South China coast, Global average surface temperature, Pacific Decadal Oscillation (PDO), El Ni?o Southern Oscillation (ENSO), SCSH index and sea surface wind-speed during the period 1960-2013, we used the methods of linear regression,Yamamoto mutation test,wavelet analysis and correlation analysis to analyze the relationship between SST and global climate change, temperature of South China coast, SST of the South China Sea and SCSH index along the South China coast over the past 54 years, we also discussed the reasons for warming hiatus phenomenon in South China coast during the period from 1998 to 2013. The conclusions were as follows: 1) The annually averaged SST of all the MEMS showed a quasi-synchronous changes and significant warming trend over the past 54 years, the climate had an tendency rate of 0.08-0.17℃/10 a, with an average of 0.12℃/10 a, the most significant warming was in winter (0.20℃/10 a), secondly in autumn (0.14℃/10a), and minimum in spring and summer (0.09℃/10 a, 0.08℃/10 a); 2) The mutation of SST occurred in 1997/1998; 3) The character of SST variation was multi-spatiotemporal, with the main cycle of 2-4 years; 4) SST changes were influenced by ENSO events, and lagged behind MEI index by about 2-4 months; 5) We also found that the main factors affecting SST were global warming, PDO, enhancement of the subtropical high and sea surface wind-speed along the South China coast.
