Long Sunlight Hours & Highest UV Index

There is a large difference in daylength between early July and the end. At the beginning, the sun rises at 04:58 and sets at 21:09, thus bringing the daytime of around 16 hours; it decreases to about 15 hours by the end of July with later sunrise at 05:29 and earlier sunset at 20:43. However, visitors still have long enough daytime for day activities. Besides, their most visits are bathed in sunshine because the average sunlight duration keeps as long as 10 hours per day. However, in view of the very high UV index of 8, you need to take both physical and chemical sun-protective measures to prevent sunburnt and heatstroke especially around midday.

Shoes: The shoes should be light-weight, breathable and comfortable; otherwise, you feel your feet stuffy and painful after trudging for a long time. Water-resistant sneakers are most recommended; if normal ones, you’d better also pack rainproof shoe covers.

Raingear like umbrellas, raincoats or rainboots can help you continue the visit when it rains lightly. Also, you should bring mosquito repellent sprays or pastes to avoid bug stings.
