Grenada is only about 12 degrees north of the equator, so the midday sun is high in the sky all year. On a clear day the UV index here commonly reaches very high or extreme levels, even in the drier months.
Cloud and haze lower the index, but thin cloud lets most UV through, and sand and water reflect it back at you. You can burn on an overcast afternoon at the beach.
