Emma,I have been a visitor to Tobago for many years,I have only once ever seen a thunderstorm and that was way out to sea.
Yes a cloud does develop over the bottom end of the Island.......but not every day and not all day.Cloud also develops over other parts.It may be fine in C'ville,raining in Castara,and fine at Crown Point.
Tobago is a tropical rainforest island so it can rain at any time,anywhere,but the difference is you get wet and five minutes later you are dry(and refreshed)!
