April Weather

Question

Our Hong Kong trip is a week away. Seems like April will have lots of rainy weather. Does it usually rain for the full day, or does it usually rain for a short period in the morning and then clear up for the rest of the day? For those in HK now, how is the weather lately?

Thanks

Answer

Heading to Hong Kong in April is generally a good choice—spring is underway and you’ll find milder temperatures compared to winter. That said, rain is more frequent in this month than in earlier spring, so it’s wise to plan with some flexibility. Below is a detailed overview of what to expect and how to prepare:

What the weather will likely feel like

In April the daily high temperatures in Hong Kong are typically around 24–26 °C (75–79 °F), with lows in the evening around 18–20 °C (64–68 °F). The humidity is beginning to ramp up as spring transitions into summer.

How frequent and long the rainfall tends to be

The chance of having a “wet day” (i.e., measurable rainfall) rises through April—from about 31 % early in the month to about 40 % towards the end.
The average rainfall for the month is moderate—around 150–175 mm over the month, with about 10–12 days of rain.
Importantly: the rain doesn’t usually mean full-day downpours in April. Many rainy days will involve morning or afternoon showers, drizzle, or overcast skies, and then clearing later in the day. The sub-tropical climate means showers can appear and disappear fairly quickly.

Recent conditions

According to the Hong Kong Observatory’s recent monthly summary, April 2025 was “dry and rather warm during the day.” That suggests favourable conditions with less extreme rain than in heavier monsoon months.

What this means for your trip

You should be prepared for some rain—carrying a compact umbrella or light rain jacket is wise.
Much of your outdoor exploring is still very much viable—even if you encounter showers, they will likely be short-lived rather than an all-day wash-out.
If a light morning rain occurs, you might still get clear or improving weather in the afternoon, so don’t cancel your plans immediately when rain appears.
Choose clothing in layers: a T-shirt or short-sleeve for the warmer afternoon, plus a light jacket or cardigan for evenings when temperatures drop a bit. The humidity will make it feel warmer during the day, but evenings can feel cooler after rain or cloud cover.
Be flexible with your schedule: if you have outdoor plans in the morning and rain is heavy then, you could adjust to move indoor or sheltered activities to that period, and keep outdoor sights for when it clears. Many tourist attractions in Hong Kong have indoor alternatives or nearby sheltered paths.

Suggested packing list

Compact umbrella or rain jacket (water-resistant).
Layered clothing: short-sleeve + light long-sleeve or jacket for evenings.
Comfortable walking shoes (with good grip in case of wet pavements).
Sunglasses/hat for when the sun comes out—UV index starts to climb in April.

In short: yes, rain is more likely in April than earlier spring months, but it does *not* mean you’ll be stuck indoors the whole time. Many days will have showers or drizzle, especially in the morning, with clear or improving conditions later. Enjoy your Hong Kong trip—and having your flexible schedule and appropriate gear will go a long way!
