Keelung is a compact port city on Taiwan's northern coast, just 45 minutes from Taipei by train, yet it feels like a different world. Mountains crowd in on three sides while the harbor cuts deep into the city center, giving every hilltop a view of container ships and fishing boats. The real draw is Miaokou Night Market, where roughly 200 numbered stalls serve some of Taiwan's most celebrated street food: crab thick soup, oyster omelets, charcoal-grilled sandwiches, and pao pao shaved ice, all beneath rows of photogenic yellow lanterns. Beyond the food, Keelung rewards explorers with wind-sculpted rock formations at Heping Island GeoPark, the rainbow-painted houses of Zhengbin Fishing Harbor, hillside temples in Zhongzheng Park, and one of Taiwan's most extraordinary cultural events, the Mid-Summer Ghost Festival.
Your best window for visiting Keelung runs from mid-October through late April, except for a stretch in late October when conditions can dip briefly. This period delivers the city's mildest temperatures and the lowest rainfall odds, making it ideal for wandering the night market lanes and hiking coastal trails at Heping Island without battling oppressive heat or typhoon threats. Winter, from December through February, sits at the heart of this window with comfortable highs around 67°F (19.4°C), perfect for eating your way through steaming bowls of soup at Miaokou. If you'd rather catch warmer days, March and April offer a strong secondary option as spring settles in with pleasant afternoons before the summer humidity takes hold. Avoid June through September, when intense heat, heavy rain, and typhoon season make outdoor sightseeing considerably less enjoyable.
Spring in Keelung, Taiwan
Spring eases Keelung out of its cool winter months and into warmer, greener territory. March and April sit squarely within the ideal visiting window, and you'll find affordable accommodation as tourism stays relatively slow through this stretch. Afternoons warm to highs of 77.2°F (25.1°C), comfortable for climbing the steps to Zhongzheng Park, where colorful temples and pavilions are spread across the hillside of Dashawan Mountain with panoramic views over the harbor. Morning lows of 67.5°F (19.7°C) mean you won't need much more than a light jacket for early strolls along the waterfront.
Showers become more frequent as the season progresses, with rain appearing roughly two to four days in a typical stretch, particularly in April and May. Bring a packable rain shell, and consider timing your visit to the night market for a Friday or Saturday evening when the famous yellow lanterns above the stalls are switched on. The L-shaped market around Dianji Temple comes alive after 5pm, and every stall is numbered with its specialty labeled in English, making it easy to hunt down the charcoal-grilled sandwiches and dingbiancuo (potside scrapings) that locals swear by.
By May, humidity starts climbing and the city edges closer to its rainy summer pattern, so the early spring weeks are your sweet spot. Use Keelung as a base for day trips along the north coast: the otherworldly rock formations at nearby Yehliu Geopark and the atmospheric alleys of Jiufen Old Street are both within easy bus range. Pack sunscreen and a hat for afternoon walks, but save the heavy-duty rain gear for later in the year.
Summer in Keelung, Taiwan
Summer in Keelung is intense. Seasonal highs average 91.1°F (32.8°C) with lows that barely dip below 80°F (26.7°C), wrapping the city in sticky, relentless warmth. Early July brings peak heat, with highs reaching 93.7°F (34.3°C) and overnight lows hovering at 81.3°F (27.4°C). This is the most precipitation-heavy season too, with rain likely two to five days in a given stretch, and August ranking as one of the wettest months of the year. Typhoons can sweep through northern Taiwan from July through September, occasionally disrupting ferries, trains, and outdoor plans with little advance notice.
Tourism peaks in June, making this the most crowded and expensive time to visit. Hotel rates climb, and the night market lanes around Miaokou feel especially packed. That said, the long summer evenings do make for atmospheric visits to the harborfront, with the sun lingering past 6:30pm. If you brave the heat, the seawater pools at Heping Island GeoPark offer some relief, and the dramatic coastal rock formations look especially vivid under strong summer light.
The one compelling reason to visit during this period is the Keelung Mid-Summer Ghost Festival, Taiwan's largest, which typically falls in August following the lunar calendar. This month-long cultural event, dating back to 1855, features elaborate float parades through the city streets, a dramatic water lantern release ceremony at Badouzi fishing port, and the spectacular illumination of Zhupu Altar overlooking the harbor. It draws thousands of visitors, so book accommodation well in advance if this is your target. Bring a compact umbrella, breathable clothing, and plenty of patience for both the weather and the crowds.
Fall in Keelung, Taiwan
Fall delivers the quietest months of the year in Keelung, with September being the least visited period overall. September still carries the tail end of typhoon season and retains summer-like warmth, so don't expect an immediate cool-down. But by mid-October conditions improve noticeably, bringing you into the start of the ideal visiting window. Highs average 81°F (27.2°C) for the season, with lows settling around 73.4°F (23°C), warm enough to enjoy the coastal scenery comfortably without the punishing heat of the previous months.
Rain arrives a few days per week, though October stands out as one of the driest months of the entire year. That makes it an excellent time to explore Heping Island GeoPark, where wind-eroded rock formations line the coast and ocean-view trails wind past sea caves and tide pools. The rainbow-painted houses at Zhengbin Fishing Harbor are especially photogenic in the softer autumn light. Accommodation is priced affordably, and you'll have considerably more breathing room at the night market stalls compared to summer's shoulder-to-shoulder crush.
As November arrives, daylight hours shorten and breezes pick up along the coast, a light wind jacket will serve you well during seaside walks. The Fairy Cave Temple, a small shrine built inside a naturally eroded sea cave on the western side of the port, is worth the short bus ride: follow the steps beyond it to catch sweeping harbor views from the hillside above. For a quieter, more personal experience of Keelung, fall is hard to beat on value and atmosphere.
Winter in Keelung, Taiwan
Winter sits at the heart of Keelung's ideal visiting window and delivers the most comfortable conditions for exploring this food-focused city on foot. Highs average a mild 67°F (19.4°C) with lows around 59.1°F (15.1°C), a welcome contrast to the sweltering summer months. The cool air makes eating your way through Miaokou Night Market far more enjoyable: steaming bowls of crab thick soup and four gods soup taste even better when the temperature cooperates. Keelung's famous rain still shows up several times a week, so keep a compact umbrella in your bag, but January records one of the lowest significant rain chances of the year.
December draws the second-highest visitor numbers, partly from cruise ship traffic through the port and partly from travelers making day trips from Taipei during the holiday season. Despite the uptick, winter crowds are manageable compared to the June peak. The shorter days, with sunset arriving around 5pm, mean you'll want to plan outdoor sightseeing for the morning and save the night market for after dark. Climbing to the Keelung Tower for a panoramic view of the harbor works well in the crisp morning air, and the hillside temples of Zhongzheng Park are far more pleasant to tackle without summer heat bearing down.
Layer up with a sweater and a waterproof outer layer for the occasional chilly drizzle. The Shen'ao Rail Bike, a short bus ride from the city center, offers a scenic ride along a converted railway track above the coast, and winter's clear days make for sharp ocean views. Pair it with a visit to the National Museum of Marine Science and Technology nearby before heading back to the harbor for an evening of night market grazing.

Travel Tips & Safety for Keelung, Taiwan
Getting to Keelung from Taipei is simple: local trains run from Taipei Main Station in about 45 minutes, and you can pay with an EasyCard (Taiwan's rechargeable transit card) without booking in advance. Buses from Taipei City Hall Bus Station are even faster, taking roughly 25 minutes. Once in Keelung, the Tourist Shuttle 99 bus connects most major attractions, from Heping Island to the night market, and the compact city center is easily walkable from the train station. Bring cash for the night market stalls, as many vendors don't accept cards.
Keelung is a safe city for visitors, but standard precautions apply: keep an eye on your belongings in crowded night market lanes, and watch for scooters when crossing streets. Typhoon season runs from roughly July through September, so if you visit during that window, monitor local weather alerts and be prepared for sudden changes to ferry and train schedules. The rain that Keelung is famous for can arrive any time of year, making a compact umbrella the single most useful item in your bag regardless of season.
