good afternoon -
follow this link to weather averages for st. john:
http://www.weather.com/weather/wxclimatology/monthly/graph/USVI0005?from=36hr_bottomnav_undeclared
may will be an awesome time to visit! i think if you look at the
monthly averages it is pretty easy to see why st john is referred to
as paradise. with average daily highs and lows fluctuating only 5 to 6
degrees year round you can count on the weather to be consistent. the
most noticeable change in weather is september through november when
temps and humidity combine to make it a very warm time to visit and
there likely is an increase in afternoon rains.
regarding room availability in may, i would not be surprised. peak
visitor season is november through the end of april. may through
august is still very busy though.
send us some pictures after your trip and we will post them in the
photo album at cinnamonbay.com... enjoy your visit!
