Pandan kondisyon nòmal, oswa ki pa El Niño, van yo komès soufle nan lwès nan Pasifik la. Van sa yo anpile dlo sifas cho nan Pasifik lwès la pou sifas lanmè a apeprè yon mwatye mèt pi wo alantou Endonezi pase alantou Ekwatè. Montre zonn nan lanmè rive nan zòn Pewou ak Ekwatè yo ki pote dlo frèt ki rich anpil nan eleman nitritif sou sifas la epi ogmante aksyon lapèch. Bò lwès la nan pasifik Ekwatoryal la karakterize pa cho, mouye, move tan presyon kòm imidite a kolekte jete nan fòm lan nan siklòn ak loraj.

During normal, or non-El Niño conditions, the trade winds blow west across the Pacific. These winds pile up warm surface water in the west Pacific so that the sea surface is about one-half meter higher around Indonesia than around Ecuador. Ocean upwelling occurs off the coasts of Peru and Ecuador bringing nutrient-rich cold water to the surface and increasing fishing stocks. The western side of the equatorial Pacific is characterized by warm, wet, low-pressure weather as the collected moisture is dumped in the form of typhoons and thunderstorms.
