Average humidity for 2004 was 74% with the highest monthly average of 78% in
+
-
August and the lowest of 71% in November.
+
-
The highest recorded humidity was 89%, and the lowest 59%.<br>
+
-
One of the consequences of this high humidity is that wet clothes can take
+
-
longer to dry than you were expecting; pack an extra set of swimming gear!

During 2004, the most rainfall in a 24 hour period was 3.50 inches (88.9m) on 21st August,
+
-
but 12.14 inches (273.64mm) fell in a 36 hour period during Hurricane Ivan on
+
-
12/13th Septembe.  In 2004, there were 220 days free of rain, and rain
+
-
was recorded on 142 days. There were 54 days on which thunder occurred.<br>
+
-
The average barometric pressure was 29.98 inches (1015.2 mb). The
+
-
highest reading of 30.23 inches (1023.7Mb) on 12th January 2004. The lowest
+
-
pressure recorded during Hurricane Ivan was 29.67 inches (970mb). Average wind
+
-
speed for the year was 10 knotts from the East.
+
-
 
+
-
Peak tourist season is mid-December to May.
+
-
 
+
-
The rainy season runs from mid-May to November. It is not uncommon for it to
+
-
be raining at one end of the island, but have brilliant sunshine elsewhere, so
+
-
it can be worth going for a drive to see another part of the island and find
+
-
the sun. Usually when it rains, it rains heavily for a couple of hours and
+
-
then stays clear for the rest of the day. However, if a tropical depression
+
-
settles over the island, it can rain for days on end, with flooding causing
+
-
severe problems.
+
-
 
+
-
==Hurricanes==
+
-
The hurricane season runs from June to November -
+
-
it tends to be the hurricanes that start in the Caribbean waters
+
-
(at the end of the season) as opposed to those that develop of
+
-
Africa (earlier in the hurricane season) that cause most damage to
+
-
the islands. The most recent brushes with hurricanes, were Hurricane Ivan
+
-
which hit in September 2004 and
+
-
caused damage estimated at CI$2.8 billion - see the news reports for
+
-
[[News2004#September_2004_-_Hurricane_Ivan|News from Cayman - September 2004]] onwards.
+
-
The islands were also hit by Hurricane Gilbert in September 1988, which
+
-
passed 30 miles south of Grand Cayman, and Hurricane Mitch in
+
-
October/November 1998 passing about 200 miles to the south.
+
-
 
+
-
Hurricane Michelle
+
-
in November 2001 caused considerable damage on the south and west sides from
+
-
South Sound all the way round to Northwest Point. (See [[News2001#November_2001| 
+
-
News from Cayman - November 2001]] for more details.)
+
-
 
+
-
However, a couple of tropical storms have also caused damage in Cayman in recent years.
+
-
 
+
-
During the 2003 storm season,
+
-
only one storm, Tropical Storm Claudette, moved through the northwest Caribbean.
+
-
Claudette passed 160 miles southwest of Grand Cayman on 10th July. The storm
+
-
produced cloudy skies, fresh winds and rough seas on 10-11 July and 2.89 inches
+
-
of rainfall was recorded.
+
-
 
+
-
Even though the hurricane season was fairly uneventful, the Cayman Islands did
+
-
experience some severe weather events in 2003. Heavy rain caused major
+
-
flooding on 19 January and 27 June in Grand Cayman. The very high rainfall
+
-
total in January was particularly unusual and included the highest 24-hour
+
-
total since records commenced in 1957. This single 24-hour total on January
+
-
18th also exceeded any previous January total on record. Flooding in both
+
-
cases was localized to southwestern Grand Cayman.
+
-
 
+
-
During the 2002 storm season,
+
-
Tropical Storm Isidore passed 9 miles north of Cayman Brac, 12:00am on 19th
+
-
September. Peak wind speed was recorded at 61 knots or 67 mph in the Brac.
+
-
Rainfall accumulation of 21.74 inches was recorded between 7:00pm on 18th
+
-
September and 6:00pm on 19 September in Cayman Brac and 13.10 inches were
+
-
recorded in Grand Cayman 17-21 September. The storm knocked down a few light
+
-
poles and caused minor damage to buildings with total damages estimated at
+
-
$30,000-$35,000. Isidore became a hurricane north of the Cayman Islands,
+
-
eventually becoming a category III hurricane in the Gulf of Mexico.
+
-
 
+
-
Tropical Storm Lili passed 4 miles north of Cayman Brac 9:00am 30th September.
+
-
In the Brac a peak wind speed of 51 knots or 57 mph and rainfall of 3.91 inches
+
-
were recorded between 7:00pm 29th September and 7:00pm the following day.
+
-
Locals also reported a few twisters. Damage costs for this system were
+
-
estimated between $312,500 and $500,000, mostly in the Sister Islands.
+
-
Lili became a hurricane northwest of Cayman Brac and eventually became a
+
-
category IV hurricane in the Gulf of Mexico.
