Weather in Iloilo in December

Shoulder season. December is shoulder season in Iloilo — cheaper, quieter, and a genuine gamble. You should expect rain on 22 days of the month, which is more days wet than dry.

December ranks 11 of 12 — near the bottom of Iloilo's year. February is the month that works, and the swing between the two is 22 points, which is a different holiday rather than a slightly better one.

Rain on 22 of the month's 31 days, 5 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Natural fibres and a second shirt for the day. At 86% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: the day barely swings — 3 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest December day reached 31 °C and the coldest night fell to 23.2 °C, and the wettest single day dropped 143 mm — roughly 82% of the month's rain in one day.

December is moderately variable: 30 mm in the driest year against 522 mm in the wettest, around an average of 175 mm. Roughly two Decembers in three land near that average, and the third does something else entirely.

Wind sits around 16 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity at 86% is the real story though — it is the number that decides how the day feels, not the 28.9 °C.

How December sits in the year

Temperatures hold steady either side: 29.2 °C in November, 28.9 here, 28.6 in January. Nothing about the timing within the month matters much. Rain is the thing that moves: January brings 6 days less of it, so pushing the dates later buys drier weather.

Daylight in December

Iloilo sits close enough to the equator that daylight barely moves all year — 11.5 hours in December, 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

Shoulder. The value months — prices ease off and you get the place closer to itself.

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

December 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, 2 days more rain. Cagayan de Oro is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

So: December works, with February the better month by 16 points if the dates can move. If they cannot, nothing here should stop you booking.
