Last year we went in late June early July. Not much rain, not really that humid. (not like Florida!!!) It was 85-90 most days .... but didn't cool off much at night. Where our house was we always had a nice breeze off the ocean which helped allot! I enjoyed it!
Thanks for getting back to me we just started a family and I thought Eleuthera might be a perfect destination for us. I would probably be going around the same time June into July. I assume it's a fish early and late senerio that time of year before the flats heat up. Might I enquire as to were you stayed?
