You see, I live in some northern country, so your photo gives me bright associations with a southern port, a taste of a cheerful and leizure life under the hot sun, swimming in tropical seas, dancing, drinking ... Therefore, there is a lot of music that will be a perfect soundtrack for your photo. For example, this track from the Planet Squeezebox accordeon music compilation (1995) : 'Hospitaleira Vacaria' by Renato Borghetti.
( I also thought about 'Calor la Vida' by Marie Laforet, but then chose the track without lyrics at all.)
