Temperatures vary little
from day to day and month to month, with average
high temperatures of 88 degrees Fahrenheit and average
low temperatures of 80 degrees Fahrenheit. Highs
occur in the early afternoon and lows occur with
showers at any time of the day, or in the early
morning if there are no showers.
Because of the low latitude,
there are only slight seasonal variations in the
length of daylight periods and the altitude of the
sun at Kwajalein. As a result, the variation of
the amount of solar energy received is small.
Severe storms and damaging
winds are uncommon in the vicinity of Kwajalein.
However, weaker depressions may form near the island
during any season. Some of these intensity and eventually
develop into typhoons after moving westward away
from the island. These depressions can cause heavy
rainfall in the Kwajalein Atoll.
The relative humidity
is uniformly high throughout the year, and is slightly
higher in the wet season than in the dry season.
The combination of high humidity and proximity of
the saltwater ocean presents a corrosion problem.
