Heat that stays with you after dark

Hong Kong is much warmer than London in June, with average daytime highs 9.6°C higher. Humidity of 88% makes that warmth a bigger consideration than the temperature alone suggests, especially when walking around. Choose loose, breathable clothing, keep water handy and leave room for indoor breaks around midday. Evenings offer little cooling, so do not assume that heading out later will mean comfortable UK-style summer temperatures. A light layer can still be useful for air-conditioned interiors, but warm outdoor clothing is not the priority. June suits travellers who tolerate sticky weather; if heat affects your energy, a packed outdoor schedule is likely to feel demanding.

Plan around rain, not uninterrupted sunshine

Rain is frequent enough that covered alternatives should be part of your daily plan, rather than a backup you rarely use. Pack a compact umbrella and footwear you do not mind getting wet, and avoid making the whole trip depend on dry outdoor days. There is plenty of daylight, at about 13.4 hours, but only around 2.2 hours of sunshine daily, so long days do not translate into long sunny spells. The figures do not mean it rains continuously, but they do make June a weak choice if clear skies are your priority. Flexible plans will serve you better than a tightly timed outdoor itinerary.
