Pretty much anything goes in dresswise in Tobago but one thing to note is that you must not go nude or topless on the public beaches. It is not allowed. It is always warm in Tobago and it is unlikely that you will need even a light cardigan unless you are in an air conditioned environment for dinner. These are rare but there is an air conditioned restaurant and a couple of air conditioned bars in La Magdalena. Most establishments just make use of the cooling breeze.
Things to Pack
insect repellent, plenty of sun cream and a wind-up torch for the occasional power cuts.
