It is best to remove the bottom leaves anyway, they are the first to show signs of fungal disease and you don't need them. You have a large tomato on the plant and it is a short plant, so is this a determinate? What variety is it.

If it has been hot over 88 degrees, tomatoes leaves will curl upwards as a result of heat stress. It is called a physiological leaf roll and it is the plant just trying to reduce water loss from the leaves. Watch or cover your tomato. If you don't have enough leaf cover it could sun scald and the birds will go after the tomato. If it is hot you can put up some kind of shade cloth or lath to give the tomato some relief from the midday sun.
Happy gardening in Hawaii. Gardens are where people grow.
