WEATHER/TIDES:
The climate is characterised as tropical marine. The weather is generally hot and
very humid with little seasonal temperature variation. The mean high temperature is
86°F (30°C) and mean low is 76°F (24°C) with an average annual rainfall of 96 in.
(2,180 mm.). The dry season runs from December to June. The remaining months (July
to November) constitute the rainy season. The months of January and February are considered
the coolest months of the year with night-time temperatures in the mid to low 70s
and generally lower humidity levels. The highest risk of typhoons is during October
and November. They can, however, occur year-round.
Guam is located in what has been nicknamed typhoon alley, and it is common for the
island to be threatened by tropical storms and possible typhoons during the wet season.
The most intense typhoon to pass over Guam in recent years was super typhoon Pongsona,
with sustained winds of 144 m.p.h. (125 knots), gusts to 173 m.p.h. (150 knots), which
slammed Guam on 8 December 2002, leaving massive destruction.
