Agree with all the above, Allison. You can resume jogging when you return. After all, your on vacation with tons of great restaurants around! Average nightly lows in SXM in July and August range from 78 to 82 (or 26 to 28 celsius), so pack light. You won't need the sweats and the hoodie. We just got back last week from eight days in Mallorca and Ibiza and those islands are at a much higher latitude than St. Maarten and it never dropped below 72 on any night we were there. Hopefully, you won't experience 42 celsius like we did one day which translates into 108 fahrenheit. That was really hot!
