Nicaragua has two distinct seasons, invierno (winter) or rainy season, and verano (summer), the dry season.
The rainy season traditionally starts around May 15 and is typically characterized by clear blue skies in the morning, clouds gathering in the afternoon, and rain in the late afternoon and evening. The rainy season usually continues through November except for a break known as "veranillo" (little summer) or the "canicula" that occurs for two weeks between July and August.
In the marina basin, consistent off-shore breezes, even during the "dry months" provide a welcome respite from inland heat.
Tides & Currents
Tides in El Estero de Aserradores will commonly be in the 5 to 7 feet range. These tides can generate currents of 4 to 5 knots so for sailboats, plan your arrival and departure to take advantage of favorable tides.
Wind and Sea
The period from December through March can be windy with 15 to 30 knot winds common. During this time however, wind waves seldom exceed one foot inside the lagoon. From dusk through the evening hours, the lagoon is typically a shimmering glass palette, protected from sea surge by the peninsula and deep estuary.
