Sunshine Hours and UV Index

How Summer Weather Affects Travel and Activities

Best Times for Outdoor Activities

This is the sweet spot for water sports. Surf Uluwatu, snorkel at Nusa Lembongan, or dive up on the northeast coast. The sea stays warm at 28–29°C, so you can leave the wetsuit at home.
If you head inland, mornings feel a bit cooler, which makes sunrise hikes up Mount Batur or wandering the rice terraces near Ubud really pleasant. July and August draw the biggest crowds because of those clear skies and lower humidity, so expect busy beaches and packed attractions.
Looking for fewer tourists but still want nice weather? Early June usually gives you a good mix of comfortable days and lighter crowds.
Packing Tips for Summer Visits

Don’t skip sun protection.
- Pack broad-spectrum sunscreen
- Grab a wide-brimmed hat
- Sunglasses with UV protection are a must
For footwear, toss in some sandals for the beach.
If you plan to hike or walk a lot, bring sturdy shoes too.
Rain doesn’t show up often, but honestly, a compact poncho or small umbrella can save the day if a shower surprises you.
You’ll want swimwear for beaches or water parks.
And if you’re out at night, especially outdoors, insect repellent comes in handy.
A light jacket or sweater helps on cooler nights in higher spots like Ubud or Kintamani.
