At certain times of year, particularly during the rainy season (August- October), the seas will be rougher, currents stronger and jellyfish can be a problem. Naturally, it is important to take care in these conditions, especially with children. If you are stung by jellyfish, the locals at beach restaurants will normally have some local remedies available that will take the initial "sting" out of things, but it is important to seek medical advice as quickly as possible afterwards to avoid any possible complications. Having said this, not many people are stung and there are warning signs placed on the beach when the "stingers" may have been washed close into shore.
