•Ribosomal 18S/28S rRNA microarray was applied to improve the detection of HAB species.•Microarray was comparable with microscopy in detecting Pseudo-nitzschia spp. and HAB flagellates and dinoflagellates.•Seasonal upwelling induced by northerly winds was found to be the driving force of HAB events....
