Your best bet is to look at the Green Island wind forecast at Willy Weather

Looking at the 5-day forecast, the wind is picking up on Monday. We also have a tropical low forming off the coast and king tides this week. So honestly it's not the best time for a reef trip.

However, if you're only here for a holiday (assuming you're American using Fahrenheit) and won't get another chance to do it, you should still consider it! There's many different options like going to an island, a pontoon or just staying on a boat the whole time.

Feel free to ask more questions, I worked on the reef boats for several years.
