Wildfire smoke has returned to the Okanagan Valley. Air quality warnings are active across the South Okanagan including Penticton, Summerland, and Kelowna. For golfers booked in over the coming days, here is what you actually need to know about playing in smoky conditions and why UV protection still matters more than you might think.
Anyone who has spent a summer in the Okanagan knows the feeling. You wake up expecting the sharp blue sky the valley is famous for and instead find a hazy orange tinge on the horizon. The mountains have softened into silhouettes. The air smells faintly of campfire. Wildfire smoke has settled in again.
For golfers, the immediate questions are practical ones. Should I still play? Is the air safe enough for four or five hours outdoors? And with the sky looking the way it does, do I still need to worry about UV protection?
The answers are more nuanced than most people expect, and one of them might genuinely surprise you.
Should You Golf During Wildfire Smoke in the Okanagan?
The honest answer is that it depends on the air quality index reading on the day you plan to play, your personal health situation, and your tolerance for risk.
BC's provincial government has posted air quality warnings across the Okanagan and South Okanagan including Penticton, Summerland, Naramata, Kelowna, and surrounding areas, advising residents to postpone or reduce strenuous outdoor activities until warnings have ended. Golf is a strenuous outdoor activity by any reasonable definition. A five-hour round involves sustained physical exertion, continuous breathing of outdoor air, and extended time in an environment where smoke concentration can change significantly from hour to hour.
The particles in wildfire smoke that pose the greatest health risk are PM2.5 particles, fine particulate matter small enough to penetrate deep into the lungs. People most likely to be negatively impacted by smoke include those with lung and heart conditions, pregnant individuals, infants and young children, people aged 65 and older, and anyone whose health is affected by a chronic condition or acute illness. If you fall into any of these categories, following official guidance to stay indoors during active air quality warnings is the right call.
For generally healthy adults without respiratory conditions, the decision is more personal. A light haze with an air quality index in the moderate range is a different situation from thick smoke with very high or hazardous readings. Checking the current air quality index for your specific location before teeing off is not optional during wildfire season. The BC government Air Quality Warnings page and the IQ Air app both provide real-time readings.
If you do choose to play during smoky conditions, early morning rounds offer the best air quality of the day. Smoke conditions can change quickly over short distances and vary considerably hour by hour, and mornings tend to carry lighter concentrations before smoke builds through the afternoon. Keep your effort level lower than usual, stay hydrated, and pay attention to how you feel through the round.
Does Wildfire Smoke Block UV Rays?
This is the question most Okanagan golfers get wrong, and the answer has real implications for how you approach sun protection on smoky days.
Yes, wildfire smoke does reduce UV radiation at the surface level. Smoke particles can scatter and absorb UV and reduce overall UV levels, and in higher concentrations more than 50 per cent of UV radiation can be absorbed. On a heavily smoke-affected day the sun looks dimmer, feels less intense, and the UV index reading will be lower than on a clear day.
Here is the part most people miss: smoke reduces UVB radiation significantly more than it reduces UVA radiation. Wildfire smoke scatters and absorbs UVB rays but transmits the majority of UVA rays, leaving people significantly exposed even under orange or gray skies. UVA reduction under moderate to heavy smoke is only 10 to 25 per cent, even when UVB drops by half or more.
This matters enormously for skin health. UVB is the radiation responsible for sunburn, the visible and painful signal that most people use to gauge their sun exposure. UVA is the radiation that penetrates deeper into the dermis, drives premature aging, suppresses local immune function in the skin, and contributes to melanoma development independent of sunburn. UVA makes up roughly 95 per cent of the UV radiation that reaches the earth's surface on a clear day.
What this means in practice is that smoky skies create a false sense of safety. The lower burn risk on smoky days leads many people to skip sun protection entirely, increasing cumulative UVA exposure over time. You will not burn as quickly on a heavily smoked-in day, and that absence of sunburn feedback makes it easy to assume you are protected. But the UVA radiation causing deeper, more serious damage is still reaching your skin at close to full intensity.
Wildfire smoke is estimated to have an SPF equivalent of only about 2. It is not sun protection. It is a thin filter that removes the signal that would otherwise tell you to get out of the sun.
The Double Exposure Problem
Wildfire smoke does not just fail to protect your skin. It adds an additional layer of damage on top of UV exposure. Smoke from wildfires is more likely to scatter sunlight all around rather than simply blocking it, meaning you can experience a double dose of damage from both UV rays and the harmful particulate matter from the smoke itself.
The fine particles in wildfire smoke generate free radicals when they contact skin, contributing to oxidative stress and cellular damage that compounds the UV damage already occurring. On a smoke-affected day, your skin is dealing with two simultaneous threats rather than one, even though one of those threats is largely invisible.
What Sun Protection Looks Like on a Smoky Day
Given that UVA penetrates smoke at close to full intensity, the correct approach to sun protection on a smoky golf day is essentially identical to a clear day. The one difference is that you may feel less urgency about it because you will not be burning as quickly. Do not let that feeling change your behaviour.
A UPF 50+ long sleeve polo blocks both UVA and UVB by fabric construction rather than sunscreen chemistry. UPF 50+ clothing works the same at 100 per cent UV index or 40 per cent UV index. The fabric does not know whether the sky is clear or smoky. It provides the same 98 per cent UV blockage regardless of conditions, making it particularly reliable on exactly the kind of ambiguous smoke-affected days where people tend to under-protect themselves.
SPF 50 broad-spectrum sunscreen on exposed skin remains important on smoky days for the same reason. The broad-spectrum designation ensures coverage against both UVA and UVB, which matters significantly on smoke-affected days when UVA is doing most of the remaining damage. Reapplying at the turn remains important even on smoky days, and UV400 sunglasses protect your eyes from the UVA that continues to penetrate the haze throughout the round.
A Note on Checking Air Quality Before You Play
The most useful thing any Okanagan golfer can do during wildfire season is develop the habit of checking air quality alongside weather before committing to a round. Two resources worth bookmarking:
The BC Government Air Quality Warnings page at aqwarnings.gov.bc.ca provides current warnings by region including the South Okanagan. When an active warning lists Penticton, Summerland, Naramata, or Kelowna, that is official guidance to reduce strenuous outdoor activity.
The IQ Air app provides real-time air quality index readings for specific locations. An AQI below 50 is generally considered good. Between 51 and 100 is moderate. Above 100 starts to carry meaningful health implications for sensitive individuals, and above 150 is concerning for anyone exercising outdoors for an extended period.
Why This Brand Exists for Days Like This
Enjoy the Vu was founded in Penticton after a melanoma diagnosis at 24. The polo was built for the Okanagan specifically, a valley where wildfire smoke is a regular part of the summer calendar and where the UV risk on a smoke-affected day is genuinely misunderstood by most people who play here.
The fact that smoke makes UV damage less visible is not a reason to stop protecting yourself. If anything it is a reason to be more deliberate, because the signal that would otherwise tell you to seek shade or reapply sunscreen is being suppressed by the same haze that is making the mountains disappear.
Check the air quality. Make a good decision about whether to play. And if you do play, protect yourself the same way you would on any other Okanagan summer day.
