Embrace the Air Conditioning
Hong Kong's indoor spaces are notoriously well air-conditioned. Always carry a light layer, like a scarf or thin cardigan, to avoid getting chilly when ducking into malls, restaurants, or the MTR.
May in Hong Kong ushers in the true start of summer, bringing with it a vibrant energy, lush landscapes, and a unique set of packing considerations. Get ready to embrace the heat and humidity while still looking stylish for city explorations and enjoying the occasional refreshing downpour.
We'll tune the list to your exact trip — dates, activities, and weather.
Expect warm and very humid conditions in Hong Kong during May. Average high temperatures hover around 88°F (31°C), with lows rarely dipping below 78°F (26°C). It's technically the start of the rainy season, so brief, heavy showers are common, contributing to the high humidity levels, often exceeding 80%. You'll enjoy plenty of daylight, with over 13 hours of sunlight, perfect for exploring all that Hong Kong has to offer.
Lightweight, breathable fabrics are your best friends in May. Think cottons, linens, and moisture-wicking materials to combat the humidity. While Hong Kong is a modern city, it's still advisable to dress respectfully, especially when visiting temples or more traditional neighborhoods. Locals tend to dress smartly even in the heat, so smart casual attire will help you blend in.

Sunscreen (SPF 30+)
Even on cloudy days, the UV index can be high, and sunburn can happen quickly when exploring outdoors.

Mosquitoes can be present, especially in greener areas, and you'll want to avoid bites.

A quick refresh on a hot and humid day can make a big difference to your comfort.
Hong Kong's indoor spaces are notoriously well air-conditioned. Always carry a light layer, like a scarf or thin cardigan, to avoid getting chilly when ducking into malls, restaurants, or the MTR.
The high humidity combined with the heat means you'll sweat more than usual. Drink plenty of water throughout the day to prevent dehydration.
The MTR (subway) is efficient, air-conditioned, and will save you from excessive walking in the heat. It connects most major attractions.
Consider visiting museums, shopping centers, or enjoying a leisurely lunch indoors during the hottest part of the day to escape the peak heat.
Don't let a sudden downpour ruin your plans. Always have a compact umbrella or a light rain jacket with you, as showers can pass as quickly as they arrive.
While the official typhoon season in Hong Kong runs from June to October, May is generally considered the precursor. The likelihood of a direct typhoon hitting in May is relatively low, but you might experience increased rainfall and stronger winds associated with tropical depressions forming in the region. Always check local weather forecasts close to your travel date.
It can be quite hot and humid for extensive outdoor activities like hiking during midday in May. If you plan to hike, it's best to go early in the morning (before 9 AM) or later in the afternoon (after 4 PM) to avoid the peak heat. Always carry plenty of water and wear appropriate sun protection.
Comfort is key! Opt for breathable, comfortable walking sandals, lightweight sneakers, or espadrilles. Avoid anything too heavy or restrictive, as your feet may swell in the heat. Waterproof options would be a bonus for unexpected downpours.
For most parts of Hong Kong, casual and comfortable attire is perfectly acceptable. However, if you plan to visit temples, monasteries, or more traditional areas, it's respectful to have your shoulders and knees covered. A light scarf or pashmina is a versatile item for this purpose.
Evenings in May are still very warm and humid in Hong Kong, so you generally won't need a heavy jacket or sweater for outdoor activities. However, indoor spaces, particularly malls, restaurants, and public transport, are heavily air-conditioned, so a light scarf or thin cardigan is advisable to prevent getting chilly.
Hong Kong has an excellent public transportation system and many fantastic indoor attractions. If it rains heavily, duck into a mall for some shopping, explore a museum (like the Hong Kong Museum of History or Science Museum), or enjoy a meal at one of the city's countless restaurants. The showers often pass quickly, allowing you to resume outdoor activities soon after.
