Amihan and Habagat

Weather in Boracay is generally divided into two seasonal weather patterns known locally as the Amihan and Habagat seasons. In the Tagalog language, Amihan means a cool northeast wind, and Habagat means west or southwest wind; south-west monsoon. Amihan and Habagat seasons are generally associated respectively with the El Niño and La Niña global weather patterns. The Amihan season is characterized by moderate temperatures, little or no rainfall, and a prevailing wind from the east. The Habagat season is characterized by hot and humid weather, frequent heavy rainfall, and a prevailing wind from the west.
On Boracay, the main indicator of the switch between the Amihan and Habagat seasonal patterns is the switch in wind direction. In most years this transition is abrupt and occurs overnight. In some years there is a period of perhaps a week or two where the wind will switch between Amihan and Habagat patterns several times before settling into the pattern for the new season. As a general rule of thumb, Boracay will be in the Amihan weather pattern from sometime in September or October to sometime in May or June and in the Habagat weather pattern for the remainder of the year. These dates can vary in individual years, though.

Daytime temperatures on Boracay generally range from 77-90º F (25-32º C) from the beginning of the Amihan season into February or March, increase to the 82-100º F(28-38º C) range until the onset of the Habagat season, and moderate back to the 77-90º F (25-32º C) range with the return of the Amihan season. During Tropical Storm periods, temperatures can fall below 68º F (20º C). Tropical Storms can impact Boracay at any time of year, but are most likely to be seen during the Habagat seaso
