Overview of Winter in Penang
Winter in Penang doesn’t mean cold; it’s all about steady warmth, high humidity, and frequent rainfall. The tropical climate brings only small shifts in temperature and rainfall compared to other times of year.
Winter Months and Duration
Winter in Penang runs from December to February. You won’t see snow or frost here, unlike in temperate regions.
Daytime highs average 29–31°C (84–88°F), and nighttime lows hover near 23–24°C (73–75°F).
Rainfall stays common, especially in December, which sees the most showers. You might get 10–15 rainy days per month, but showers tend to be short and intense, not all-day affairs.
Day length barely changes, with about 11–12 hours of daylight year-round. You can plan outdoor activities without worrying about big swings in sunlight.
General Climate Characteristics
Penang’s winter weather feels hot and humid, with relative humidity usually above 80%. Mornings might feel a bit fresher, but afternoons get sticky with all the heat and moisture.
Sea temperatures stay warm, averaging 28–29°C (82–84°F). Swimming and water activities stay comfortable all season.
Winds usually stay light, though coastal spots might catch gentle breezes that help a bit with the heat. Thunderstorms pop up, especially in December, but they don’t last long.
Comparison to Other Seasons
Compared to the wettest months, September to November, winter in Penang tends to feel a bit drier, even though December can still bring heavy rain.
Rainfall drops off in January and February, which makes these months a bit more appealing for travel.
Unlike the mid-year months from May to August, which get really humid and unsettled from the southwest monsoon, winter brings more stable weather. You’ll still deal with humidity, but not as many long-lasting storms.
Temperatures hardly change throughout the year, so winter mainly stands out for its rainfall pattern. That makes it a pretty comfortable time to check out Penang’s beaches, markets, and cultural sites.
Typical Winter Temperatures
Penang’s winter doesn’t bring cold weather like temperate countries experience. Instead, you get warm tropical weather with only small differences between day and night.
Humidity, rainfall, and cloud cover matter more than any real drop in temperature.
Average Daytime Temperatures
In December, January, and February, daytime temperatures in Penang usually stay between 29°C and 32°C (84°F to 90°F). Penang’s spot near the equator keeps things steady.
Most afternoons feel humid, especially if clouds trap the heat. Sunshine hours drop just a little compared to mid-year, but honestly, you probably won’t notice.
There’s no “cold” period like in four-season places. Rain showers or overcast skies might drop the temperature by a degree or two, but it’s still warm by most standards.
Nighttime Temperature Range
At night, temperatures usually dip to 23°C–25°C (73°F–77°F). This small drop makes it easier to sleep, though humidity keeps the air feeling a bit damp.
Homes and hotels rarely need heating, and most just use fans or light air conditioning. Even before sunrise, you won’t see it fall below 22°C (72°F) under normal conditions.
The sea around Penang stays warm, so evenings near the coast often feel a bit warmer than inland. That effect keeps nighttime cooling mild.
Temperature Fluctuations
Winter in Penang brings minimal daily variation compared to temperate climates. The difference between the highest and lowest temperature in a day rarely tops 7–8 degrees Celsius.
Rain showers might cool things down for a bit, but temperatures bounce back quickly once the rain ends.
Cloudy days can feel a little less hot, but humidity keeps things from ever feeling truly cool.
This steady pattern makes it easy to plan outdoor activities. No need for heavy clothes—just pack lightweight, breathable fabrics to handle the heat and humidity.
Rainfall and Humidity Patterns
In winter, Penang gives you steady warmth with noticeable rainfall and high humidity. Even though temperatures don’t change much, rain and moisture shape your daily comfort and plans.
Average Precipitation Levels
Penang has a tropical rainforest climate, so rain falls year-round. In winter, rain doesn’t vanish, but it’s less intense than peak monsoon months.
February is usually the driest month, with about 122 mm of rain. December often brings higher totals, closer to 250–300 mm, but that’s still less than the heavy autumn downpours.
Here’s a rough idea of average rainfall in winter:
| Month | Average Rainfall (mm) |
|---|---|
| December | 250–300 |
| January | 180–220 |
| February | ~122 |
You’ll probably get some rain no matter when you visit, but totals are moderate compared to the wettest time of year.
Rainy Days Frequency
Rain in Penang’s winter usually comes in quick, heavy bursts, not all-day storms. December sees about 18–20 rainy days, January has 12–15, and February drops to around 9.
So, you’re likely to run into showers every few days, especially early in the season. By February, rain becomes less frequent, which makes it easier to plan outdoor stuff.
Since rain spreads out over many days, you’ll want to carry light rain gear or an umbrella. Showers often hit in the afternoon or evening, leaving mornings clearer for exploring.
Humidity Trends
Humidity in Penang stays high all year, and winter’s no exception. Average relative humidity runs from 75% to 85%, with December often feeling the stickiest thanks to more rain.
You might notice the air feels sticky in the evenings, especially near the coast. Breezes along the waterfront or in open spots can help a bit.
If humidity gets to you, plan indoor breaks during the hottest part of the day. Most hotels, restaurants, and malls have air conditioning, which helps balance out the dampness.
Sunshine and Daylight Hours
Penang’s tropical climate gives you steady daylight, even in winter. The number of sunshine hours shifts a bit with seasonal rains, but you’ll still get several hours of direct sun each day and nearly the same day length all year.
Average Daily Sunshine
During winter, Penang gets about 5 to 7 hours of direct sunshine per day. December and January usually bring clearer skies than October and November, which are rainier.
January is often the sunniest, sometimes topping 8 hours of sunshine daily. December sees closer to 6 hours because of passing showers and clouds.
Even on wetter days, you’ll spot breaks of sunshine between showers. Morning or early afternoon is often your best bet for outdoor plans before heavier rain rolls in.
Compared to other tropical spots, Penang’s winter sunshine is moderate. Here’s a quick look:
| Month | Avg. Sunshine Hours per Day | Notes |
|---|---|---|
| December | ~6 hrs | More cloud cover, scattered rain |
| January | ~8 hrs | Clearer skies, drier conditions |
| February | ~9 hrs | Sunniest winter month |
Daylight Duration in Winter
Daylight in Penang barely changes because it’s so close to the equator. In winter, you’ll get about 11 hours and 45 minutes to 12 hours of daylight each day.
The sun rises around 7:15 AM and sets near 7:20 PM. These times only shift by a few minutes across the season, so your daily rhythm stays predictable.
You don’t get those long winter nights or super short days like in higher latitudes. That makes planning outdoor activities a lot simpler.
Travelers often appreciate the steady daylight, since it pairs well with the warm weather for sightseeing, beach trips, and evening walks—no early darkness to worry about.
Sea and Water Temperatures
Penang’s coastal climate keeps the sea warm year-round, even in winter. Water temperatures stay steady, so you can swim or do water activities without worrying about cold snaps.
Average Sea Temperature
In December, January, and February, sea surface temperatures stay between 84°F and 85°F (29°C). That’s about as stable as it gets for a tropical destination.
December averages around 84.9°F, January is close at 84.5°F, and February nudges up to 85.0°F. The region’s humid, equatorial climate keeps things consistent.
Penang doesn’t get the sharp drops in water temperature that some places see in winter. Even at its coolest, the sea is still warm enough for long swims.
Penang’s spot near the equator and the South China Sea’s influence keep these temperatures steady. You don’t need to plan your trip around seasonal water changes.
Suitability for Water Activities
Since the water stays warm, you can swim, snorkel, or dive anytime in winter. The sea rarely drops below 27°C (81°F), which is great for casual swimming.
Most days are calm, though rain can sometimes mess with water clarity. December brings more rainy days (about 13), while January and February are drier, with only 8 and 5 rainy days. Less rain usually means clearer water for snorkeling or diving.
The warm sea temperature supports marine activities all year. Whether you like a quick dip by the beach or longer sessions in deeper water, you’ll find comfortable conditions—no wetsuits needed.
These steady temperatures make Penang a solid pick if you’re hoping to enjoy the sea during winter.
Wind and Atmospheric Conditions
Penang’s winter brings steady tropical weather, with light to moderate breezes and stable air pressure. You’ll usually get calm conditions, with only small shifts in wind or visibility that might affect your comfort or travel plans.
Typical Wind Speeds
In the winter months, winds in Penang usually stay pretty gentle. You’ll notice average speeds hovering around 4 mph, which is light enough that strong gusts rarely grab your attention.
This kind of breeze makes outdoor activities like walking, cycling, or just sightseeing a lot more comfortable than in places with harsher seasonal winds.
You’ll probably feel the most noticeable breezes in February, March, and April. During those months, wind speeds can climb closer to 8–9 mph.
Even then, the winds feel mild and don’t really disrupt daily plans. Penang’s spot as an island helps keep air movement more stable in winter, unlike some coastal regions that get battered by monsoons.
If you’re hanging out near the coast, you might catch slightly stronger breezes in the late afternoon.
Inland, especially around George Town, things usually stay calmer.
These patterns make winter a pretty easy time to enjoy both city and seaside activities without having to worry about the wind.
Air Pressure and Visibility
Penang’s air pressure in winter doesn’t really change much. Most days, you’ll see average readings around 757 inHg, which just means the tropical conditions stay steady.
You won’t run into big swings in pressure that could bring sudden, unsettled weather.
Visibility tends to be good, thanks to the steady atmosphere and the lack of extreme weather changes.
Fog almost never shows up, and skies are usually clear, especially in December and January when sunshine is more common.
Rain showers pop up now and then, but they’re quick and usually stick to one area.
After a bit of rain, the air feels fresher and visibility even improves a bit.
That makes it easier to plan sightseeing trips since you can count on decent weather most of the time.
Travel Tips for Visiting Penang in Winter
Penang’s winter brings slightly cooler days, lower humidity, and less rain than other seasons.
You’ll find it easier to enjoy outdoor activities and cultural events without feeling uncomfortable.
Best Activities for the Season
Winter’s lighter humidity and rain mean you can spend more time outside.
Strolling through George Town’s historic streets feels more pleasant, and you can check out street art, temples, and markets without worrying much about rain.
The beaches at Batu Ferringhi and Tanjung Bungah are also at their best, with calmer seas and clearer skies.
Swimming, parasailing, or just relaxing on the sand are all great options.
Nature lovers have a lot to look forward to.
Penang Hill offers cooler air and beautiful views, while Penang National Park is perfect for hiking to Monkey Beach or the lighthouse at Cape Rachado.

Recommended Packing List
Pack light, breathable clothes because the days get pretty warm, usually hovering between 25°C and 30°C. Cotton shirts, shorts, and dresses feel great in this weather.
Bring a light jacket or sweater for those cooler evenings, especially if you’re heading up Penang Hill or hanging out near the coast.
You’ll want comfortable walking shoes for exploring George Town or wandering the national park trails. Sandals work for the beach, but skip them if you plan on walking a lot.
Toss in a small umbrella or compact raincoat in case you run into short showers. Don’t forget sun protection—sunscreen, sunglasses, and a hat are must-haves.
If you’re visiting festivals, it’s respectful to wear modest clothing when you enter temples. A scarf or shawl makes it easy to cover your shoulders if you need to.
Insect repellent comes in handy in outdoor spots, especially parks or anywhere near water. It’s just one of those things that’ll help you enjoy your evenings without too much fuss.
