อากาศมะนิลา เดือนกันยายน

Regulars call this one of the best-weather months of the year, driven by the cool, dry Amihan winds that push in from the northeast, though they're equally clear the rainy season has only just ended, so a late typhoon can still catch travellers off guard. Our row backs that transitional, still-warm read, 31C reading as a hot 34C, over 23.6C nights, with 158.7mm of rain still falling across 11.2 days. Regulars are specific that when a typhoon does hit this late, it can be a genuinely nasty one precisely because it's unseasonal, sometimes stranding ferry travellers elsewhere in the country for days. Humidity stays high even as temperatures ease. The sea sits at a warm 28.9C. The record: humidity 80 percent, 8.5 hours of sun, an 18.3 kph wind and AQI 43.

November is when the monsoon recedes here and the high season begins - cooler than the summer, drier than the rains, and our row's 102mm across 9.8 days is a fraction of what August brings. The catch the Philippine boards repeat is that this is still typhoon season, which normally closes around the 10th of December, and a typhoon does not mean a wet day but a halted one: ferries cancelled, flights grounded, plans rearranged. Their advice is to leave a spare day in the itinerary rather than to avoid the month. Heat holds at 32.1C reading as 36C over 24.1C nights, with a 29.7C sea. The record: humidity 81 percent, 9.4 hours of sun and AQI 53.

April is the hot end of the Philippine dry season - the rains have not started, the sun is overhead, and regulars warn that 34C reads far higher with the humidity. Our row says 34.3C feeling like 38C, with 22.8mm of rain across 2.8 days. The month's other event runs against the usual logic. Holy Week, whose date moves, is the biggest holiday in the country and fills every beach and every flight - but the better-off leave Manila for it, so the capital is quieter than usual and hotels discount to fill rooms. A crowd that empties a city is worth knowing about. The record: 24.6C nights, 11.4 hours of sun, a 30.4C sea and AQI 76.

March closes the good half of the Manila year. The forum's window is January to March, when it is a little cooler and a little less humid than the rest of the year, and their description of February and March is idyllic if what you want is very warm to hot days with virtually no rain - one regular's line is that you would be surprised to get enough rain to form a puddle on the street. Our row agrees at 8.9mm across 2.4 days. The caveat is the direction of travel: by the end of March it is sweltering, above 30C as a matter of course and touching 34C on a hot day, and April onwards is worse. The record: 33C days that feel like 36C, 23.4C nights, 11 hours of sun and a 28.4C sea.
