Short answer
October to early December is the best window. The summer rains have stopped, humidity drops, daytime temperatures sit in the mid twenties and the city spends its days outdoors. November is the single strongest month.
Avoid late June to September if outdoor plans matter to you. About 80% of Hong Kong's roughly 2.4 metres of annual rain falls between May and September, and typhoon season runs June to October with the peak from July to September. August is the wettest month, with rain on around four days out of seven.
Crowds follow a different calendar from weather. The two weeks that hurt most in 2026 are the Lunar New Year period (15–23 February) and National Day Golden Week (1–7 October). Book October and December hotels six to ten weeks ahead.
Hong Kong by month
Temperatures are typical daytime highs and lows, not forecasts. Expect any given year to run a couple of degrees either side.
| Month | Typical temperature | Rain | Crowds | Verdict |
|---|---|---|---|---|
| January | 14–18°C | Lowest of the year | Medium | Cool, dry, good value — but check the Lunar New Year date |
| February | 15–19°C | Low | Extreme during Lunar New Year | Cheapest outside the holiday; the holiday itself is the worst week |
| March | 18–22°C | Rising | Medium | Mild, occasional fog and drizzle |
| April | 22–26°C | Moderate | Medium–high (Easter) | Warm and green; Easter week is busy |
| May | 26–30°C | High | Medium | Humidity arrives; hotel discounts at their best |
| June | 29–32°C | High | Medium | Typhoon season opens; plan flexible days |
| July | 30–33°C | Very high | High (school holidays) | Hot, humid, storms — indoor-heavy itinerary |
| August | 29–34°C | Wettest month | High | The hardest month for outdoor plans |
| September | 28–32°C | Very high early, easing later | Medium–high | Late September turns a corner |
| October | 25–29°C | Low | High (Golden Week) | Best weather, busiest first week |
| November | 21–26°C | Low | Medium–high | The best all-round month |
| December | 17–21°C | Low | High over Christmas | Clear and cool; festive crowds late in the month |
October to early December: the window to aim for
This is why everyone recommends autumn. Rain totals collapse, humidity falls away, and the hiking trails, ferry islands and harbourfront all become comfortable for a full day rather than an hour.
The one thing to plan around is the first week of October. Mainland China's National Day Golden Week runs 1–7 October 2026, and Hong Kong's own National Day holiday falls on 1 October. Hotel rates climb, and the border crossings into Shenzhen turn into long queues. Arriving on 8 October instead of 1 October gets you the same weather at a materially lower price.
Late November is the sweet spot for anyone who wants the weather without the crush. The Mid-Autumn Festival lands in late September and the Chung Yeung holiday in mid-October, so November has almost no holiday pressure at all.
January to March: cool, dry and festival-heavy
Winter in Hong Kong is mild by northern-hemisphere standards and genuinely dry. January averages the fewest rain days of the year. The catch is that buildings are built for cooling, not heating, so a 15°C day feels colder indoors than the number suggests.
The 2026 problem month is February. Lunar New Year's Day falls on 17 February, and the three statutory Hong Kong holidays run 17–19 February. On the mainland, the Spring Festival rest period runs 15–23 February 2026 — nine days, the longest in the calendar. That is the single biggest inbound travel week of the year. Book flights and hotels months ahead, or travel in the second half of the month once the crowds have gone.
April and May: warm, green and underrated
April is comfortable, and May brings the Dragon Boat Festival and rising humidity at the same time. Rain totals climb sharply in May, and the first typhoon warnings of the year can appear late in the month.
May and the early part of June are not peak season, and hotel discounts in this window are the deepest of the year outside February. Afternoon thunderstorms are common but usually short.
June to September: heat, rain and typhoons
Be honest with yourself about this stretch. Daytime temperatures run 29–34°C with humidity above 80%, which makes midday walking genuinely draining. Rain arrives in heavy bursts rather than drizzle. The trade-off is lower prices outside the July and August school holidays.
Typhoon season runs June to October with the peak from July to September. Most systems pass without affecting a trip, but one direct hit can shut ferries, cancel flights and close outdoor attractions for a day or two. Build a spare indoor day into any summer itinerary.
Hong Kong's 2026 public holidays and the crowd spikes
Hong Kong observes 17 statutory public holidays, and it does not use the mainland's swapped working-weekend system. A holiday that lands on a Sunday simply moves to the next weekday, which extends a few weekends unexpectedly.
| 2026 date | Holiday | Effect on travel |
|---|---|---|
| 1 January | New Year's Day | Countdown crowds on 31 December; one-day spike |
| 17–19 February | Lunar New Year (3 days) | The biggest spike of the year, plus a nine-day mainland holiday |
| 3–7 April | Good Friday, Easter and Ching Ming cluster | A long weekend; regional visitors fill hotels |
| 1 May | Labour Day | Mainland holiday 1–5 May in 2026 — border queues |
| 19–21 June | Dragon Boat Festival | Beach and harbour events; a busy weekend |
| 1 July | HKSAR Establishment Day | One-day spike, ceremonies on the harbourfront |
| 25–27 September | Mid-Autumn Festival period | Lantern events; the Mid-Autumn day after falls on 26 September |
| 1–7 October | National Day and Golden Week | The second-biggest spike; peak hotel pricing |
| 19 October | Day after Chung Yeung Festival | Long weekend, hiking trails crowded |
| 25–26 December | Christmas Day and the first weekday after | High-season pricing and festive crowds |
What to pack, season by season
- November to February: layers. A light jacket, sweater and long trousers handle almost every day. One warmer layer for harbour nights or Victoria Peak, which runs a few degrees cooler than the streets.
- March to May: a thin waterproof shell and a compact umbrella. Fog can sit on the harbour for a morning and burn off by noon.
- June to September: one set of clothes you can get soaked in, plus a dry bag for phone and passport. Quick-dry fabric beats cotton. Two pairs of shoes that can dry overnight.
- Any season: a power bank, since you will be scanning QR codes and checking transport apps all day. Your Octopus card covers the MTR, buses, ferries and most convenience stores, which removes a lot of small-change friction.
Mistakes that make a Hong Kong trip feel worse than it is
- Judging the month by temperature alone. Humidity and rain decide whether a day outdoors works, not the number of degrees.
- Booking the first week of October. Golden Week is the most expensive and most crowded non-holiday week of the year here.
- Planning only outdoor days in summer. Build in museums, malls and temples so a storm does not wipe out the day.
- Ignoring mainland holidays. Chinese New Year, Labour Day and Golden Week push mainland visitors across the border and into the hotels.
Frequently asked questions
What is the best month to visit Hong Kong?
November. Rain has stopped, humidity drops, daytime temperatures sit in the mid twenties and skies are clearer than at any other point in the year. Late October and the first half of December are nearly as good and slightly cheaper.
When is typhoon season in Hong Kong?
Roughly June to October, with the highest risk between July and September. Storms rarely last more than a day or two, but a typhoon signal of 8 or above suspends ferries and outdoor attractions. Check the official weather service during your stay.
How much does it rain in Hong Kong?
Annual rainfall averages about 2.4 metres, and roughly 80% of it falls between May and September. August is the wettest month, with rain on about four days out of seven. January is the driest.
Which Hong Kong holiday weeks should I avoid?
Chinese New Year and National Day Golden Week. In 2026 the mainland Spring Festival rest period runs 15–23 February and Golden Week runs 1–7 October. Both push hotel prices up and fill the border crossings, the Peak Tram and the Star Ferry.
Is Hong Kong too hot in July and August?
It is hot and humid rather than unvisitable: daytime temperatures usually run 29–34°C with humidity above 80%. Plan indoor blocks in the middle of the day, carry water, and treat outdoor plans as movable because of afternoon thunderstorms.
What should I pack for Hong Kong in winter?
Layers rather than a heavy coat. January daytime temperatures sit around 14–18°C and buildings are not heated, so a light jacket, a sweater and long trousers cover most days. Add one warmer layer if you plan a night on the harbour or a trip up to Victoria Peak.
Does Hong Kong have a rainy season?
Yes, from May to September. It does not rain all day every day; the pattern is heavy showers and thunderstorms that pass, plus occasional multi-day wet spells. A compact umbrella and a dry bag for electronics handle it.
What is the cheapest time to visit Hong Kong?
February outside the Lunar New Year period and the deep summer months of July and August, when heat and storms cut demand. Hotel rates drop most in these windows. Avoid the weeks immediately around the public holidays, when prices jump back up.
