UV Index Guide
for Golfers in Thailand
Thailand sits near the equator with UV levels that can burn unprotected skin in under 10 minutes. A 4-hour round demands serious sun strategy.
Typical Peak UV

What is the UV Index?
The UV Index measures the strength of ultraviolet radiation reaching the ground on a scale from 0 to 11+. It was developed by the WHO to help people understand when sun protection is necessary.
Thailand, located between 6°N and 20°N latitude, receives intense UV radiation year-round. Even on cloudy days, up to 80% of UV rays penetrate through, making sun protection essential for golfers regardless of weather.
Unlike temperature, which you can feel, UV damage is invisible until it's too late. You won't feel the burn building during your round — symptoms appear hours later.
Why Golf is High-Risk
- 4-5 hoursof continuous sun exposure per round
- Peak hoursMost rounds overlap 10am-2pm (highest UV)
- ReflectionSand bunkers and water reflect UV upward at your face
- SweatingWashes off sunscreen faster than normal
UVA vs UVB
UVB causes sunburn and directly damages skin DNA. UVA penetrates deeper, causing premature aging and contributing to skin cancer. Both are intense in Thailand. Use broad-spectrum sunscreen that blocks both.
UV Index Levels Explained
What each level means for your round of golf
Minimal protection needed. Enjoy your round freely.
Sunglasses on bright days. Sunscreen optional for sensitive skin.
Early morning (before 8am), late afternoon (after 4pm), heavy overcast.
Standard protection recommended. Comfortable for a full round.
SPF 30+ sunscreen, hat, and sunglasses.
Morning (8–9am), late afternoon (3–4pm), partly cloudy midday.
Take sun protection seriously. Seek shade between shots when possible.
SPF 50+ sunscreen (reapply every 2h), wide-brim hat, UV-blocking clothing, sunglasses.
Mid-morning (9–10am), mid-afternoon (2–3pm), overcast rainy season midday.
Avoid midday rounds. Play before 9am or after 3pm. Maximum protection required.
SPF 50+ (reapply hourly if sweating), UPF 50+ clothing, wide hat, quality sunglasses, seek shade constantly.
Standard midday (10am–2pm) most of the year. The Thai default.
Do not play midday. Early morning or twilight rounds only.
All of the above plus long sleeves, neck cover, and UPF arm sleeves.
Clear sky midday from March to May. UV can exceed 13 in April.
Thailand UV by Month
Peak midday UV index throughout the year
Hottest UV: March–May
The sun is nearly directly overhead, peak UV hits 12-13. Combined with 35-40°C heat, this is the most dangerous time for outdoor golf. Book 6am tee times or play twilight rounds.
Lower UV: Nov–Dec
The "cool season" brings slightly lower UV (peak 9), pleasant temperatures (25-32°C), and the best overall golf weather. Still protect yourself — UV 9 is "Very High" by global standards.

Sun Protection Kit for Golfers
Essential gear for every round in Thailand
Sunscreen
- SPF 50+ broad-spectrum — minimum for Thailand's UV levels
- Water/sweat-resistant sport formula — essential in 30°C+ heat
- Apply 30 min before your round, reapply every 2 hours
- Don't forget: ears, neck, back of hands, and lips (SPF lip balm)
Clothing
- Wide-brim hat or bucket hat — standard golf caps leave ears/neck exposed
- UPF 50+ golf shirts — lightweight, breathable UV-blocking fabrics exist
- UV arm sleeves — popular with Asian golfers, lightweight and effective
- Light colors reflect more UV and keep you cooler
Eye Protection
- UV400 sport sunglasses — blocks 99-100% of UV radiation
- Polarized lenses reduce glare from water hazards and sand
- Wrap-around style prevents UV from entering from the sides
- Long-term UV exposure causes cataracts and macular degeneration
Smart Play Strategy
- Book 6-7am tee times — finish before peak UV at noon
- Use cart shade between shots and during waits
- Hydrate aggressively — UV + heat = rapid dehydration
- Umbrella between shots — common in Asia, provides instant shade
The Long-Term Risk
Why sun protection on the golf course matters beyond today
of lifetime UV exposure occurs during outdoor recreation — golf is a major contributor
sunburns double your risk of melanoma. Regular golfers in Thailand can exceed this quickly
hours of annual sun exposure for a weekly golfer. That's a significant cumulative dose
This isn't meant to scare you away from golf. It's a reminder that consistent sun protection is an investment in your health. Professional golfers on the PGA Tour now treat sun protection as seriously as their swing — you should too. A wide-brim hat and SPF 50 take 30 seconds to apply and can prevent decades of skin damage.
