How Much Sun Can You Take?
Thailand's UV is strong enough to burn unprotected skin in under 15 minutes. A 4-hour round needs a plan. Here's yours.
The quick answer
The UV Index runs from 0 to 11+. In Thailand, midday UV hits 10–13 year-round. Here's what to do:
Early morning (before 9am) or late afternoon. Basic sunscreen is enough.
SPF 50+, hat, sunglasses, reapply every 2 hours. Use cart shade between shots.
Burns in under 10 min. Book 6am tee time or twilight round. No exceptions Mar–May.
The invisible trap: Unlike heat, you can't feel UV building on your skin. The burn develops during your round but you won't notice it until hours later. By hole 9, the damage is already done. That's why protection before you start matters more than anything.
UV through the day
Your tee time is the single biggest decision for UV exposure. Here's a typical Thai day:
4–5 hours continuous exposure
Most outdoor activities are shorter. A full round means sustained UV accumulation.
Reflection doubles it
Sand bunkers and water hazards reflect UV upward — hitting your face, neck, and chin.
Sweat washes off sunscreen
30°C+ heat means constant sweating. Your SPF 50 is reduced to nothing by hole 6 if you don't reapply.
Clouds don't save you
Thin clouds let 80% of UV through. You can burn on overcast days — especially deceptive.
UV by month
Thailand has intense UV year-round, but March–May is especially dangerous. Here's the peak midday UV by month:
Peak danger: March–May
Sun is nearly directly overhead. UV hits 12–13. Combined with 35–40°C heat, midday golf is punishing. Book 6am tee times or play twilight.
Best months: Nov–Dec
Cool season brings UV 9 (still "Very High" globally!) but 25–32°C temps make it manageable. Best overall golf weather — still wear sunscreen.
Your sun protection checklist
Ranked from most to least impactful. Do the top 3 at minimum.
Book an early tee time
6–7am start means you finish before peak UV. This single decision cuts your UV exposure by 60–70%. It's the highest-leverage move.
SPF 50+ sunscreen, reapply every 2 hours
Broad-spectrum, water/sweat-resistant sport formula. Apply 30 minutes before your round. Don't forget ears, neck, back of hands, and lips.
Wide-brim hat (not a cap)
Standard golf caps leave ears, neck, and face exposed. A wide-brim or bucket hat protects all of them. Your caddie has an umbrella too — use it.
UV400 polarized sunglasses
Blocks 99–100% of UV. Polarized lenses cut glare from water and sand. Long-term UV exposure causes cataracts — protect your eyes every round.
UPF clothing and arm sleeves
UPF 50+ shirts and arm sleeves are popular with Asian golfers for good reason. Lightweight, breathable, and they never need reapplying.
The bigger picture
of lifetime UV exposure comes from outdoor recreation
sunburns doubles melanoma risk
hours/year of sun for a weekly golfer
This isn't about fear — it's about habit. PGA Tour pros treat sun protection as seriously as their swing. A wide-brim hat and SPF 50 take 30 seconds. Do it every round and you're covered for decades.
