Miami’s oceans are populated by jellyfish, which often float just below the surface and can have a nasty sting. Keep an eye out for life guard warnings and signs along the beaches and if you start to feel a sharp, burning sensation or muscle spasms, seek medical attention.
Southeast Florida is victim to hurricanes every four years or so, although major hurricanes occur less frequently. Florida receives about 60 inches of rain annually (around 3 times average rainfall in London, for example), so be prepared for all weathers, especially turing the rainy season between June and September.
Unlike in the majority of the US, tipping in Miami is usually added directly to the bill – usually it’s between 18 and 20%. You can ask for this to be lowered or raised at your discretion, although lowering your tip is generally considered rude by the service industry in the United States, so don’t do this unless your dining experience has been of particularly low quality.
