The analysis of the phytoplankton and environmental parameters of the time series in Alfacs and Fangar bays time series (north western Mediterranean) from 1990 to 2009 reveals certain trends. There is an increase in the average water column temperature by 0.11, 0.01, 0.80 and 0.23 ºC for spring, summer, fall and winter respectively in Alfacs Bay and 1.76, 0.71, 1.33, 0.89 ºC for spring, summer, fall and winter in Fangar Bay. The trends in phytoplankton populations show a shift in the timing of occurrence of Karlodinium spp. blooms and an increase of the Pseudo-nitzschia spp. abundance. There is no correlation between the average seasonal temperatures and toxic phytoplankton abundance
