In this paper, the features of climate change over Xisha in recent 50 years have been systematically examined by using the basic meteorological data in 1958-2005. The results showed that annual mean surface temperature rose by about 1.0℃, with a warming rate of approximately 0.19℃/(10 a), which is close to the average value of whole country. The seasonal mean temperature was also on the rise, with the most obvious ascending trend in winter and spring. The annual precipitation had a big fluctuation and no significant trend was seen. For seasonal precipitation, only spring had obvious linear ascending trend. The surface wind speed had a significant trend to decrease, especially in recent 30 years the annual mean wind speed was smaller than the normal year. The wind speed in four seasons also had significant decrease, especially in autumn and winter. Also, the annual sunshine duration, total cloud amount took an significant decreasing trend, while the low cloud amount had a bit increase.
