Boracay in September: Weather and Sea Conditions

Boracay has no PAGASA station. The first rainfall column is the PAGASA climatological normal for Roxas City, Capiz, the nearest listed station, on a different coast of Panay¹. The second is NASA POWER’s 2001-2020 climatology, a reanalysis model evaluated at the island’s coordinates and multiplied from a daily rate to a monthly total². Temperatures and humidity are from that model. Sea-surface values are monthly means of hourly Open-Meteo model values for 2015-2024³.

Sources:¹ for the gauge column,² for rainfall and temperature in the model,³ for sea temperature.

Sources disagree Going into October the two rainfall sources move in opposite directions. The Roxas City gauge rises from 213.5 to 304.9 mm, the wettest month of its year; the model falls from 382 to 341 mm¹². In September the model figure is about 1.8 times the gauge figure. Roxas City is across Panay and the model is a smoothed grid-cell estimate, so neither is a measurement on the island. Plan for a wet month, and do not read September as the drier end of the season on the strength of either column alone.

The model’s mean daily high of 30.8 C is 0.6 C above August’s, and relative humidity is 84% against 85% in August². PAGASA places June to November in the rainy season⁴. The PAGASA normals page describes the values as 30-year averages but does not name the years or label the rainfall unit; the figures behave as millimetres of monthly rainfall¹.

Boracay has two monsoons. Amihan is the northeast monsoon; Habagat is the southwest monsoon. GMA News reported the 2025 Habagat start as 30 May⁵. On 7 October 2025 PAGASA said the Habagat had been weakening for weeks and that the country was moving toward the Amihan season, to be declared in the coming weeks⁵. The declaration came on 27 October 2025, citing a surge of northeasterly winds over Extreme Northern Luzon, and PAGASA said rough sea conditions and shear lines were also expected in the season⁶. GMA also reported, on 7 October 2024, that PAGASA had declared that year’s Habagat season officially ended⁷. The sources used here give no 2026 declaration.

A University of the Philippines study models the island as oriented northwest to southeast. White Beach faces the southwesterly winds directly and Bulabog the northeasterly ones, so under southwest conditions the study finds higher wind and wave setup at White Beach and lower at Bulabog, and the reverse in northeast conditions⁸.

Boats between Caticlan and Boracay have been limited at Public Storm Warning Signal No. 1¹¹ and stopped at Signal No. 2⁹¹⁰ in the cases found. Those storms fell in November and December; the sources used here date no September storm on the island. The signals and precedents are on typhoons and cancelled boats. The sources behind this page do not give a port for September: see the ports page.

The sources used for this page date no festival or programme on Boracay in September, so none is listed. Dated peaks elsewhere in the year are on Boracay peak dates.

No arrivals report in the sources gives a September figure. The Malay tourism office recorded 1,040,847 tourists from 1 January to 15 June 2023, and January was the busiest month of that period at 177,860¹². That says nothing about September, and this page does not call the month busy or quiet.

Late September sits just before the handover to Amihan, which PAGASA declared on 27 October in 2025⁶. For a trip at the end of the month, leave a spare day before any flight home from Caticlan; the Coast Guard decides on the day whether boats sail. Entry steps at the jetty port are in Boracay entry requirements.
