•San Juan is celebrated by lighting bonfires on beaches.•The incidence of burns increases during these festivities.•Most patients are men between the ages of 20 and 40 years.•Burn incidents usually occur between midnight and 2 am.•No relationship was found between meteorological variables and burns.

AimSan Juan (Summer Solstice) is an annual festival celebrated in many parts of Spain on June 24 by lighting bonfires on beaches and in open air. The aim of this study is to analyse the patient profile of those sustaining burns the night before San Juan.Material and methodsThe data of 179 patients who sustained burns on June 23 and 24 between 2005 and 2015 were collected retrospectively.ResultsThe average age of the patients involved in this study was 27.33 years, with males constituting a higher proportion. Hands were the most affected area of the body, and the average burn area was 3.39%. No statistically significant relationship was found between the tidal times and the number of patients with burns, although the latter increased at low tide (p = 0.177).ConclusionsThe results of this study can guide prevention campaigns during these festivities in the future.
