Kuching is hot and humid every day of the year, and it rains a lot: expect daytime highs around 31-32°C, humidity that sits above 80% most afternoons, and roughly 4,000mm of rain annually spread across every month. There’s no typhoon risk here, but there’s also no dry season in the way a visitor from a temperate climate might picture one.
Kuching sits just north of the equator on the island of Borneo, which is the whole explanation for why the weather barely changes month to month. If you’re weighing up when to actually book a trip around this, the best time to visit Kuching breaks that down properly; this piece is about what the climate itself does, and why the rain here deserves to be taken seriously rather than waved off as “just a shower.”
TL;DR
- Daytime highs run 31-32°C year-round, nights around 23°C, with humidity commonly above 80%.
- Kuching is one of the wettest cities in Malaysia: annual rainfall runs on the order of 4,000mm.
- The Northeast Monsoon (roughly November-March, per MetMalaysia) brings the heaviest, most sustained rain and can flood low-lying parts of the city.
- June-August is the relatively drier stretch, but no month in Kuching is genuinely dry.
- Kuching sits below the typhoon belt, so it gets heavy downpours and the odd squall, not typhoons.
- Carry an umbrella every day, all year, since there’s no real “rainy season” separate from the rest.
How Hot and Humid Does It Get?
Kuching’s temperature barely moves through the year. Daytime highs sit around 31-32°C, nights cool down to about 23°C, and that pattern repeats in January the same as it does in July.
What changes the experience isn’t temperature, it’s humidity. Relative humidity commonly sits above 80% in the afternoons, and that’s the number that actually determines how a day feels. A 31°C day in Kuching is a different proposition to a 31°C day somewhere dry: the air holds onto heat and moisture in a way that makes the short walk from a Grab to the front door of a mall feel like a small event. Locals deal with this the obvious way, by moving slower in the middle of the day and treating air conditioning as a genuine utility rather than a luxury.
There’s no cool season to look forward to, either. Some parts of Southeast Asia get a noticeably cooler stretch for a month or two; Kuching doesn’t. The one or two degrees of variation you see across the year barely registers against the humidity, which is the dominant factor in how the climate actually feels day to day. If you’re used to distinct seasons, the adjustment isn’t to a new temperature range so much as to a climate that doesn’t really have a range at all.

Does It Rain a Lot in Kuching? (Yes, Genuinely)
Kuching is one of the wettest cities in Malaysia, and the annual rainfall total, on the order of 4,000mm, isn’t a number to gloss over. That’s not a “rainy season city with a few wet months.” It’s a city where rain is a structural part of every month on the calendar, and pretending otherwise does new arrivals no favours.
The Northeast Monsoon, which MetMalaysia places at roughly November through March, is when that rainfall concentrates hardest. This is the period that brings the heaviest, most sustained downpours, the kind that can run for hours rather than the twenty-minute afternoon burst you get in the drier months, and it’s also the period most likely to flood low-lying parts of the city. If you’re moving here and picking a neighbourhood, that’s a genuinely practical thing to factor in.
June through August is the relatively drier stretch, and it’s the closest thing Kuching has to a “good weather” window. But drier is a relative term here: you’ll still get rain most weeks, just less of it and with more gaps between downpours. No month on the calendar is what you’d call dry.
The pattern day to day is fairly consistent outside the heaviest monsoon weeks: mornings tend to start clear or lightly cloudy, and the rain arrives in the afternoon or early evening as the heat builds. It’s not universal, and the Northeast Monsoon months bring rain at more random hours, including overnight, but if you’re planning a walking tour or an outdoor visit, mornings are generally the safer bet.
Flooding is the practical downside worth naming plainly. Low-lying parts of the city, particularly areas near the Sarawak River and its tributaries, have a history of localised flooding during the heaviest monsoon rain. It isn’t a constant threat and most of the city functions normally through the wet season, but anyone renting or buying property here during the November-March stretch should ask directly about a specific area’s drainage and flood history rather than assume it isn’t relevant.
How Much Does the Rain Actually Disrupt a Day?
Less than the annual rainfall figure suggests, most of the time. A typical downpour outside peak monsoon season lasts somewhere between twenty minutes and an hour, hits hard while it’s happening, and then clears. Life in Kuching adapts around this rather than stopping for it: shops keep serving, hawker stalls under cover keep cooking, and Grab drivers keep moving, just more slowly and at a premium during the worst of it.
The exception is the sustained monsoon rain from November to March, where a single spell can run for several hours rather than clearing quickly, and where back-to-back wet days are common enough that outdoor plans need a backup. If you’re booking anything weather-dependent, a hike, a boat trip to Bako National Park, an outdoor event, that’s the window to build the most slack into.
Does Kuching Get Typhoons?
No. Kuching sits below the typhoon belt that hits the Philippines and parts of Vietnam and Taiwan, so it doesn’t get typhoons. What it does get is heavy monsoon rain and the occasional squall, sometimes referred to locally as a Sumatra squall, a sudden burst of wind and rain that can roll through quickly and hard, usually in the early morning.
That’s a genuinely useful thing to know if you’re comparing Borneo against other parts of Southeast Asia that do sit in the typhoon path. It doesn’t mean Kuching’s weather is mild, the rainfall numbers above make clear it isn’t, but it does mean you’re not planning around storm season the way you would in Manila or Hanoi.
Occasional haze is a separate issue worth a brief mention, since people sometimes confuse it with typhoon weather when they’re researching the region. Haze in Borneo is linked to land-clearing fires elsewhere in the region during drier stretches, most often around the June-August window, and it can affect air quality for a few days at a time in some years and not at all in others. It’s unrelated to the rain and monsoon patterns covered here, but it’s the other weather-adjacent thing worth knowing about if you’re planning an extended stay.
Planning Around the Weather, Month by Month
If you’re timing a visit, June to August gives you the best odds of stringing together a few dry days in a row, though “dry” here still means an umbrella in your bag. November through March is when to expect the heaviest, most disruptive rain, and it’s worth building slack into any outdoor plans during that window rather than assuming the forecast will cooperate.
Whatever month you land in, the practical habit is the same: carry a small umbrella every day, because Kuching’s downpours tend to arrive fast and heavy rather than build up with warning, even under a clear-looking sky. Showers are often short, sometimes clearing within thirty minutes, but they hit hard while they last. For a fuller breakdown of which months actually suit your trip best, the best time to visit Kuching covers that decision in more detail than a climate page needs to.
The Weather You Actually Need to Plan For
Kuching’s climate isn’t going to surprise you once, it’s the same hot, humid, wet pattern every single month, and the only real variable is how much rain falls in a given week. Pack for humidity, budget time for downpours, and skip the umbrella at your own risk.
