CLIMATE

The most misunderstood phenomenon of Shemya is its weather. People
who have stopped here a few hours in inclement weather obtain a wrong
impression and tend to exaggerate conditions. The following climato-
logical survey, 1944 - 1954, is factual and reliable for that period.

          TEMPERATURE                    PRECIPITATION

Mean Annual-----------38.7 Deg "F"       Mean Annual------------25.4"

     CLOUD CONDITIONS
It is cloudy 88.2% of the time.
Bright sunny periods are
frequent but of short duration.
Shemya and the blue seas are
beautiful in the sunshine.

          FOG
Fog occurs almost daily during
June, July and August. Ceilings
100 feet with less than 1/16
mile visibility are not uncommon.
However, conditions change
frequently and rapidly. Varia-
tions from 1/16 of a mile to
two miles visibility occur in a
matter of seconds.
