This study of upwelling off Cape Frio (Africa) provides new insights using daily high resolution satellite and ocean-atmosphere reanalysis datasets in the period 1985–2015. The annual cycle of SST follows two months behind the net heat balance and wind stress curl, reaching a minimum in July–September. Ranking the daily SST record, an intense upwelling event stands out: 26–29 August 2005 is studied. A coastal wind jet >10 m s−1 and cold plume < 14C develops west of Cape Frio, co-located with cyclonic wind stress curl. Daily time series 1985–2015 reveal warming SST +.035C/yr and diminishing winds −0.025 m s−1/yr.
