Abstract Aquatic heatwaves are increasing in frequency, intensity, and duration worldwide. While increases mean water temperatures linked to enhanced phytoplankton biomass, it is unclear how alter dynamics lakes at an ecosystem scale. We investigated changes surface chlorophyll during 29 summer between 2008 2019 3 north temperate lakes. These vary staining were either references or manipulated with nutrients top predator additions. The manipulations provided a variety of nutrient, grazing, light conditions heatwave non‐heatwave conditions. Surface concentrations increased 24 out heatwaves. In the low‐nutrient reference lake increase was 57% while two experimental 127% 183%. Overall, effects whole‐lake experiments variable but still context for possible patterns amid diverse set food web nutrient
