October SSTs Warm Slightly

The longer term look on the oceans is well worth a read

Science Matters

October Sea Surface Temperatures (SSTs) are now available, and we see a slight upward response after a steep drop in September.  The rise was led by anomaly increases of about 0.06 in both the Tropics and SH, compared to drops of about 0.2 the previous month. NH was virtually the same as September. Global average anomaly changed as much as the Tropics and SH, but remains lower than the three previous Octobers.

HadSST is generally regarded as the best of the global SST data sets, and so the temperature story here comes from that source, the latest version being HadSST3.

The chart below shows SST monthly anomalies as reported in HadSST3 starting in 2015 through October 2017.
