The brown macroalga  Fucus vesiculosus  is a foundation species in temperate rocky shores, subjected to seasonally fluctuating environmental conditions. To obtain a more complete picture of the seasonality of  F. vesiculosus  ecophysiology in the northern Baltic Sea,  in situ  photochemistry, elemental ratios and chlorophyll  a  and  c  content of the alga were investigated in field campaigns conducted in different months throughout the year during 2017. Carbon, nitrogen, carbon to nitrogen ratio and chlorophyll  a  and  c  content of the alga varied substantially throughout the year, with highest carbon content observed in summer, and highest nitrogen content in winter. C:N ratio in  F. vesiculosus  apical tissue ranged from 8.6 in February to 48.3 in July. Chlorophyll  a  and  c  content followed inversely the seasonal patterns of ambient irradiance. High chlorophyll  a  and  c  content in winter was associated with higher maximum photosynthetic efficiency of energy conversion (Fv/Fm), but not with efficiency of photosynthetic energy conversion under light limitation (α). Electron transport rate correlated strongly with seawater temperature, and the highest electron transport rates were observed in summer and correlated with highest internal carbon content of the alga. Redundancy analysis conducted on measured environmental variables against physiological responses identified day of year, temperature and macronutrients in seawater as the most important variables driving the observed seasonal patterns in  F. vesiculosus  ecophysiology. The results suggest elevated temperatures may increase  Fucus  growth and photosynthesis rates in the study area. HighlightsTwo distinct physiological states of  Fucus vesiculosus  were identified.The most important variables driving responses were season, temperature and macronutrients.Fucus  ecophysiology shows substantial seasonality in the northern Baltic Sea.
