For travelers

Know the UV before you land

Sun strength changes dramatically from one destination to the next. A trip toward the equator or up a mountain can mean far stronger UV than you're used to. Suntic tells you before it catches you out.

Suntic 10-day UV forecast for planning trips

The sun behaves very differently depending on where you go. Travel closer to the equator and UV is stronger year-round; head to altitude and it intensifies further; cross into the other hemisphere and the seasons (and the peak UV months) flip entirely.

What changes UV when you travel

Latitude

The closer to the equator, the higher the typical UV.

Altitude

UV rises roughly with elevation, so mountains and high cities are stronger.

Season & hemisphere

Southern-Hemisphere summer runs December to February.

Reflection

Snow, water and sand all bounce extra UV onto you.

Plan your trip around the sun

Before you travel, check the destination's typical UV with our UV index by city guides, and use Suntic's 10-day forecast to plan excursions. Suntic Pro lets you save multiple places, so you can watch UV at home and at your destination at once.

Don't get caught out abroad

A common holiday mistake is assuming a cool or breezy destination has gentle sun, yet many high-altitude and southern destinations have intense UV. Go by the live index, pack broad-spectrum SPF 30+, and remember a tan is your skin reacting to UV, not a sign of safety. See what UV means for your skin.

FAQ

FAQ

How do I check the UV index for a destination?
Read our city UV guides for typical patterns, and use Suntic for the live reading and 10-day forecast at your location once you arrive.
Why is the sun stronger in some countries?
Mainly latitude and altitude: places nearer the equator and higher above sea level receive more intense UV. Clear skies and reflective surfaces add to it.
Is UV stronger in the mountains?
Yes. UV increases with altitude, and snow reflects much of it back up, so mountain trips can mean surprisingly high exposure even when it's cold.
