PRELIMINARY April 2011 SST Anomaly Update

The April 2011 Reynolds OI.v2 Sea Surface Temperature (SST) data through the NOAA NOMADS website won’t be official until next Monday. May 8th. Refer to the schedule on the NOAA Optimum Interpolation Sea Surface Temperature Analysis Frequently Asked Questionswebpage. The following are the preliminary Global and NINO3.4 SST anomalies for April 2011 that the NOMADS website prepares based on incomplete data for the month. I’ve also included the weekly data through April 27, 2011, but I’ve shortened the span of the weekly data, starting it in January 2004, so that the variations can be seen.

PRELIMINARY MONTHLY DATA

Based on the preliminary data Monthly NINO3.4 SST anomalies are at -0.68 deg C.
