When is the Fiesta de Playa San Juan?

[SuzyQ]

I noticed from a banner on the street that we are well into the fiesta at Playa San Juan, does anyone know if tonight (Monday) is a major night (fireworks etc)? Thinking of dropping my son and his friend there on the way to Los Gigantes tonight.... TIA
