As GaKaye says, SXM is sub tropical so there is not a lot of difference in sunrise and sunset times across the year... With the island at 18 degrees north latitude, the sun is NORTH of you at noon time for almost two months in June and July. Your noontime shadow on the summer solstace actually points south.

In addition, you do not get the much longer daylight hours in the summer like in New England when the earth's tilt has the sunrise in the Northeast and the sunset in the northwest...

Twilight is very short...morning and night.

Also, St Martin stays on Atlantic Standard time year around..
