About Maui Winds: Wind on Maui is
dominated by trade winds, and Local wind effects such as that
Venturi, Bernoulli, and sea-breeze effects, which can drastically
affect the wind-scape across the island. Each location on Maui will
have a specific wind profile, and syndrome. The island's local
geography interacts with the trade wind flow, and drastically alters
its direction and strength. The wind often blows from two or more
different directions at once. Airflow is sometimes divided by the
mountains, or funneled and channeled along the valleys. The position
and proximity of neighboring islands will affect the winds also. The
best guesses of wind conditions will come from a combination of good
weather data, local knowledge and eye witness accounts.
Wind? Wind is the result
of unequal heating of the earth's surface. The equator receives the
most sunshine, and heats up more than the polar regions. The land
heats faster that the ocean etc. When the heat rises it warms the
air expands changing its density and causes it to rise. Rising air
creates a drop in air pressure. Descending air increases the air
pressure. Differences in air pressure at the earth's surface are
what cause the winds at the surface. Wind is the movement of air
flowing from a high pressure area to a low pressure area. The
greater the difference between the high and the low pressure, the
stronger the resulting wind will be. We can see the highs and the
lows on the weather maps. Extreme lows are called tropical storms or
cyclones. Weather systems move across the earth's surface, generally
from west to east.
Trades in the northern hemisphere blow from about 30degrees north of
the equator toward the equator in a north easterly direction. The
trade winds blow typically between 11-13mph, and can be stronger
depending on localized effects such as land forms. When a high
pressure system is north of Hawaii, it creates northerly winds in
the islands. When there is an especially low pressure cell south of
the islands the wind will be extra strong. When a High pressure cell
is parked directly over the islands, the trade winds will shut down.
When the trades are absent, there will still be light winds caused
by convection (heating of the land). The convection wind is called a
sea-breeze. The sea breezes are present during trade conditions but
are usually dominated by the stronger trade winds. Trade Winds, and
sea breezes can work together to compliment the wind, or can work
against each other to cancel the wind.
Sometimes the position of the high and low pressure cells are
reversed, and we have a high to the south and a low to the north.
This will cause the wind's direction to reverse. The winds will then
blow from the southerly direction. In Hawaii the southerly winds are
called Kona winds. The word "kona" means leeward. So the kona winds
are blowing onto the (usually) leeward sides of the islands. Kona
winds often bring rain and stormy conditions. Konas are associated
with tropical storms and can become quite intense and devastating.
Effects: Hawaii is a mountain range in the middle of a flat
ocean. The islands are the mountain tops protruding from the sea
surface. Some peaks reach over ten thousand feet above sea level and
up into the air. These peaks and ridges create a major obstacle for
the wind. Where possible the wind will go around the peaks, and will
tend to flow along valleys. The heights of peaks and the topography
of the land, and in particular the orientation of the peaks and
valleys will determine where the wind will flow. On Oahu there are
two mountain ranges directly across the path of the trade winds.
These act as a barrier to the wind. The north shore is protected
from the trade winds, and this creates ideal no-wind surfing
conditions there. The north shore of Maui has two large mountains,
one at each end, and a large valley in the middle. The north
easterly trade winds are forced to go between the two mountains and
flow along the valley and across to the other side of the island.
This creates that ideal conditions on Maui's north shore for
windsports, like windsurfing and kiteboarding. This also creates
extreme offshore winds on the south shore that can be dangerous to
unwary sailors, especially small craft.
offshore winds: On any island you can find one side with onshore
winds, and one side with offshore winds. Choosing one location over
another will depend on the conditions you are seeking for your
particular sport. Strong offshore winds are potentially hazardous to
windsurfers, kayakers, and kiteboarders. Never sail in offshore
winds unless you have dedicated support boats with you. Also strong
Onshore winds can be dangerous to kiteboarders. Kiteboarders should
not attempt to ride when the wind is blowing directly onto the land.
Any mishap could potentially cause the kiter to crash onto the land.
The ideal conditions are side-onshore, or side shore winds.
