Weather in Iloilo in January

Shoulder season. January is shoulder season in Iloilo — cheaper, quieter, and a genuine gamble. The heat itself is manageable at 28.6 °C, but 84% humidity is what you will actually feel.

January ranks 3 of 12 in Iloilo. Only February scores clearly higher, and the difference is small enough to be settled by price rather than weather.

This is persistent light rain rather than storms: 16 wet days but only 2 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Natural fibres and a second shirt for the day. At 84% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: the day barely swings — 3.6 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest January day reached 31.5 °C and the coldest night fell to 21.9 °C, and the wettest single day dropped 51 mm — roughly 54% of the month's rain in one day.

January is moderately variable: 23 mm in the driest year against 217 mm in the wettest, around an average of 95 mm. Roughly two Januarys in three land near that average, and the third does something else entirely.

Wind sits around 18 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity runs at 84%, high enough to notice on the warm days without dominating them.

How January sits in the year

Temperatures hold steady either side: 28.9 °C in December, 28.6 here, 29.3 in February. Nothing about the timing within the month matters much. Rain has already shifted: 6 days fewer than December had.

Daylight in January

Iloilo sits close enough to the equator that daylight barely moves all year — 11.6 hours in January, against a range of just 1.2 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

An inland climate

Despite being inland, the year stays fairly even: 7.3 °C between the year's warmest afternoons and coldest nights.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

January in Iloilo versus nearby

If Iloilo is one option among several, the nearby comparison is worth making. Cebu City is close enough to be a coin toss — within a degree on temperature, 4 days more rain. Cagayan de Oro is the weaker option in January — within a degree on temperature, 4 days more rain.

So: January is effectively as good as it gets here — 6 points behind February, which is inside the margin where the weather stops being the deciding factor and price starts being it.
