What to do today
About Bali
Kuta and the beaches of South Bali sit at about 8° south of the equator, where the sun tracks high overhead for most of the year. Surfing, beach clubs and rice-terrace day trips in Ubud all mean long stretches outdoors with little shade.
Sand, water and your real UV
The chart above is UV arriving from the sky. Bali’s beaches add reflected UV from pale sand and from the ocean’s surface, so surfers and swimmers get dosed from below as well as above — a common reason people burn on the underside of the chin and the backs of the knees while surfing.
When UV is strongest here
Being so close to the equator, Bali runs high to extreme UV all year with only modest seasonal swing. The dry season (roughly April to October) brings the clearest skies; the wet season adds cloud cover that trims but doesn’t eliminate strong midday UV.
On the beach and in the water
Surf lessons and long boat rides to the Gili Islands or Nusa Penida keep you exposed for hours with the ocean reflecting light back up. Rice-terrace and volcano hikes inland add open, unshaded trail on top of that.
Sun protection tips for Bali
- Wear a UPF rash guard for surfing and snorkeling — sunscreen alone washes off quickly in the water.
- Reapply reef-safe, water-resistant SPF 30+ every two hours.
- Start volcano hikes (Batur, Agung) before dawn, both to catch sunrise and to be off the exposed summit before peak UV.
- A wide-brim hat beats a cap on the beach — it also shades the ears and neck.
