HadSST3 Maps from earlier months

HadSST3 anomalies map for April 2018


Map of monthly average Sea surface temperature (SST) anomalies (relative to 1961-1990) from HadSST3. White areas represent gridboxes containing no SST data. Although the data have been quality controlled, the uncertainties in some grid boxes are larger than in others. Large uncertainties arise when the grid box average is based on only a small number of observations, or on measurements from a small number of ships or drifters. Where uncertainties are largest (see below) the variability of the observed SST anomalies will be higher with unexpectedly high or low values. When assessing the reliability of the SST anomaly fields it is helpful to refer to the estimated uncertainties shown below. Data can be found on the download page
