Just back from Wonder 4 day that left Feb 27 and returned March 3rd.
It rained the first day (very hard). Was cloudy the second day while we were in Bahamas and the temps were probably around 70 degrees. Rained again at night.
3rd day (to be our CC day) it was partly sunny with a cool breeze and 70 degrees (missed CC).
4th day Same weather, maybe a little warmer missed CC again (spend entire morning watching to see if we could get in).
If you like it warmer, I would suggest going in April or May. As a canadian 70 degrees was fine for us!
