Weather in Zamboanga in January

Shoulder season. January sits in between. You will get good days and you will lose some. You should expect rain on 19 days of the month, which is more days wet than dry.

Zamboanga barely has seasons. January scores 57 out of 100 against a best of 68 in February — a gap small enough that the month you choose matters far less here than the week you choose.

This is persistent light rain rather than storms: 19 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 82% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: the day barely swings — 2.2 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest January day reached 30.7 °C and the coldest night fell to 24.4 °C, and the wettest single day dropped 46 mm — roughly 46% of the month's rain in one day.

January is moderately variable: 7 mm in the driest year against 207 mm in the wettest, around an average of 99 mm. Roughly two Januarys in three land near that average, and the third does something else entirely.

Wind is light at 13.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 82%, 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, 28.7 here, 28.9 in February. Nothing about the timing within the month matters much. Rain is the thing that moves: February brings 6 days less of it, so pushing the dates later buys drier weather.

Daylight in January

Zamboanga sits close enough to the equator that daylight barely moves all year — 11.8 hours in January, against a range of just 0.8 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 27.9 °C in January — warm enough that the water offers no relief from the heat. The sea peaks at 29.8 °C in May and bottoms out at 27.5 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

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

January in Zamboanga versus nearby

If Zamboanga is one option among several, the nearby comparison is worth making. Budta is the weaker option in January — 2.4 °C warmer, 2 days less rain. Cagayan de Oro is close enough to be a coin toss — within a degree on temperature, 1 day more rain.

So: January works, with February the better month by 11 points if the dates can move. If they cannot, nothing here should stop you booking.
