Start by combining the sugar and water for the simple syrup and heat it on the stovetop while stirring until the sugar dissolves. This will make your simple syrup. Once the sugar dissolves, remove from heat to cool.
While the simple syrup cools, juice the lemons and puree or muddle the strawberries and acai.
Combine all ingredients in a large pitcher and stir until well mixed.
