Start of the warm season
The Galapagos Islands
The
climate in the Galapagos islands, though under the equator, cooled by
the Humboldt current, and is characterized by two main seasons: (1) the
warm, wet season (January to April), and (2) the cool, dry season (May
to December). December to May is the best season for visiting the islands
when the weather is pleasantly warm and the winds are light.
The rainy season, which lasts from January to April, is marked by decreased
winds and warmer sea currents. The days are warm and the seas are calm
during these months. Heavy rains in the upper elevations send streams
of water down the slopes to even the lowest island points.
From June to November the weather is overcast and cool. The water around
the islands is surprisingly cold and the meeting of the Humboldt current
and the warm air sometimes causes mist over the islands. Occasionally
the Humboldt current is replaced by the warm El Niño current, a
phenomenon which can affect weather conditions throughout the South Pacific.
From May to December, when the winds blow in a southeasterly direction,
the shores of the southern islands are bathed in cool waters, chilling
the air and creating unusually cold conditions for equatorial islands.
During this period, rain is scarce on the coastal regions. Only plants
that can survive long periods of time without water -- such as lichens
and cacti -- thrive in these areas. Higher up, however, clouds of moisture
support the thick vegetation.
