Summer plane spotting: heat, UV protection, heat haze and gear

July, the start of the school holidays, leisure airline traffic in full swing – and along the fence there is not a single tree for two hundred meters. Summer days are both a curse and a blessing for spotters: lots of movements on the runways, long windows of light and often stable high-pressure weather. At the same time you stand for hours on heated asphalt in the sun, the image over the runway wobbles, and the camera gets so hot you hardly want to touch it. This guide shows you how to do plane spotting in summer safely and with good pictures: UV protection, heat, shimmer and protecting your gear.

Summer at the fence: the short answer

You get safely through a summer spotting day with three basic rules: use the edges of the day, protect your skin and head consistently, and regularly bring body and gear into the shade. Early morning delivers cool air, little shimmer and soft light. The midday hours with a steep sun are the weakest time photographically anyway – use them for a break. And if you stand at the fence for hours, drink regularly before you get thirsty.

What makes airports special: spotting positions are almost always on open ground. The areas around runways are deliberately kept free of tall vegetation, and parking lots and terraces consist of asphalt, concrete and light surfaces. Shade is scarce, and the surroundings reflect additional heat and UV light back at you.

UV radiation: reading the index correctly

The UV index is the most important number for your sun protection – more important than the air temperature. Even on a windy day with a pleasant-feeling 24 degrees, UV exposure can be high. The BfS divides the index into levels:

UV index	Exposure	BfS recommendation	What that means at the spot
1–2	low	usually no protection needed	sunburn still possible during long sessions
3–5	moderate	protection required: shade at midday, clothing, hat, sunglasses, sunscreen	a normal spring or summer day in Germany
6–7	high	protection required	long sleeves and a hat are a must, breaks in the shade
8–10	very high	protection absolutely necessary, avoid the midday hours	schedule your session for morning and evening
11 and above	extreme	highest protection level	typical for vacation spots in the south and in the tropics

At the airport there is an effect that the weather report does not show: reflection. Asphalt, light-colored facades and pale sand throw UV radiation back, so the actual exposure can be above the stated index. On a light-colored observation deck or on the sandy beach of a vacation spot, you therefore get radiation not just from above but also from the side and from below.

Sun protection that works at the fence

• Clothing first: A thin, long-sleeved shirt protects more reliably than any cream, because it does not sweat off or rub off. Loose-fitting, breathable fabrics in light colors heat up less.
• Head and neck: A wide-brimmed hat or a cap with neck protection prevents sunburn on the back of your neck – the spot that constantly points upward when you look through the viewfinder. It also protects against sunstroke, which long sun on an uncovered head can trigger.
• Sunscreen, generously: Apply plenty to uncovered skin and refresh the protection after sweating and wiping. Reapplying maintains the protection but does not extend your time in the sun.
• Sunglasses: Good sunglasses with UV protection spare your eyes when you stare into the bright sky for hours. For shooting, push them up; with polarized lenses some camera displays look dark or blotchy.
• Don’t forget your hands: The hand on the lens often sits in the sun for hours. Thin gloves or cream help – but sunscreen does not belong on the front lens or viewfinder, so wipe your fingers first.

Heat: what your body has to endure at the spot

Standing in the sun for hours is physically more taxing than it feels. You move little, concentrate on the next approach and often notice thirst and exhaustion late. On top of that comes the heat given off by the heated ground.

The heat warnings of the German Weather Service are a useful guide. It warns of strong heat stress when the perceived temperature is above about 32 °C and it barely cools down at night, and of extreme heat stress at a perceived temperature above 38 °C. The perceived temperature takes into account not only the air but also sun, wind and humidity. If such a warning is in effect for your region, you shorten the session, move it to the morning or simply stay home.

Good to know: the hottest time of day is usually not midday but the afternoon. It is coolest just after sunrise. An evening spotting session after a hot day can therefore still feel like an oven for a long time.

Recognizing warning signs

Heat stroke can become life-threatening. According to the German Red Cross, typical signs are a raised body temperature, hot and dry skin, a rapid pulse, fatigue, cramps, vomiting, as well as dizziness and confusion. If you notice such signs in yourself or others at the fence:

For yourself the rules are: drink regularly before you get thirsty, and avoid physical exertion in great heat – so don’t march to the most remote end of the runway in the midday sun with a full backpack. If you are out with children, pay particular attention to head covering, shade and drinking; tips are in the guide Plane spotting with kids.

Heat haze: why pictures turn soft

Hardly anything is as annoying in summer as a perfectly exposed taxiing shot in which the registration and details blur anyway. The culprit is heat haze: over heated asphalt, warm air rises and mixes turbulently with cooler air. Because warm and cold air bend light by different amounts, the image is constantly distorted a little on its way to your lens. With a long focal length you magnify this effect.

The most important countermeasures follow from that:

• Shorten the distance: The less hot air between you and the subject, the sharper it gets. An aircraft on the nearby taxiway is the better subject in summer than one at the far end of the apron.
• Stand higher: The strongest turbulence is close to the ground. Elevated positions such as the Munich Airport visitors’ hill (Besucherhügel) or the Hamburg Airport observation deck look down at a steeper angle onto the surfaces and through less hot air near the ground.
• Photograph aircraft in the air: On approach or just after liftoff, the line of sight runs over less hot ground and passes through the layer near the ground faster.
• Pick the time of day: In the morning the ground has barely heated up yet. After a rain shower or under an overcast sky the shimmer is often weaker as well.
• Shoot bursts: The shimmer fluctuates from moment to moment. From a short burst, one frame is often noticeably sharper than the others.

The technique behind it and more tricks are described in detail in the article Avoiding heat haze. How a high sun darkens the underside of the fuselage and when the light is best at your spot is explained in the guide Planning around sun position.

Protecting your gear from sun and heat

Cameras are robust, but not unlimitedly heat-proof. Manufacturers state an operating temperature in the technical specifications; for many models the upper limit is about 40 °C ambient temperature – the Fujifilm X-H2S is specified for roughly –10 to +40 °C at 10 to 80 percent humidity without condensation. That sounds like plenty of margin. In blazing sun, however, a black body heats up much more than the surrounding air.

Problem	What happens	Remedy
Body in direct sun	Electronics and sensor get warm, image noise can rise, some cameras shut off video	into the shade between shots, light-colored cloth or umbrella over it
Batteries in the heat	Lithium-ion batteries age faster at high temperatures	spare batteries in the shade, in the bag rather than on the car roof
Gear in a parked car	the interior heats up in the sun far above the outside temperature	never leave the camera in the car, take the backpack with you
Dust and pollen	dry summer air carries dust onto the front lens and, when changing lenses, onto the sensor	change lenses out of the wind, use a lens hood, keep the cap on
Sunscreen on fingers	greasy film on lens, viewfinder and display	wipe your fingers, keep a microfiber cloth with you
Condensation	a cold camera from an air-conditioned car fogs up in humid warm air	let the camera adjust for a few minutes in the closed bag

A light-colored camera backpack heats up less than a black one – which bags work for long telephoto lenses is covered in the article Camera backpacks for plane spotting. If dust has collected on the sensor despite all precautions, the guide Cleaning your camera and sensor helps.

Spots in the south: vacation with extra sun

Many spotters combine the summer vacation with a visit to an airport – Mallorca, the Greek islands or the Caribbean rank high. There the sun is yet another class stronger: the farther south you stand, the steeper it is at midday, and UV indexes in the very high to extreme range are no exception in high summer.

• At the runway end in Skiathos you stand without shade right at the approach. A hat and water are a must here, and you won’t take the jet blast of departing aircraft head-on anyway.
• At Maho Beach on Sint Maarten tropical sun, pale sand and water come together – exactly the surfaces that reflect UV radiation strongly.
• Around Palma de Mallorca Airport it is peak season in summer with leisure airlines such as Condor, TUIfly or Eurowings. If you spot there, it is best to schedule your sessions in the morning.

For vacation spots there is one more rule: sand and salt water are poison for lenses and cameras. Keep your gear in a closed bag and clean it thoroughly after a day at the beach.

Consideration and conduct on hot days

Summer also means crowds at popular spots. A few points that count especially on hot days:

• No barbecue fires, no cigarettes in the grass: Dry meadows around airports burn quickly. Take cigarette butts and glass bottles back with you.
• Keep access roads clear: If you want to park in the shade, it is easy to end up in fire lanes or farm tracks. Keep emergency routes free – on hot days especially they may be needed.
• Don’t look for shade beyond the fence: Shaded areas behind barriers or on operational areas are off limits. The article Proper conduct at the airport fence sums up what is allowed at the fence.
• Look out for each other: A spotter who seems confused or suddenly slumps needs help. At the fence there are often regulars standing next to each other who have known each other for years – a quick glance at your neighbor never hurts.

A ladder is a good tool for a clear view over the fence in summer too, but it gets hot in the sun. Whether and where you may set one up is covered in the article Ladders, step stools and tripods at the airport fence.

What to watch out for

• Plan by UV index, not by feel. Wind and wisps of cloud feel cool, but the UV radiation still gets through.
• Build in breaks deliberately. Use the midday hours with the weakest photo light for shade, food and drink.
• Check departure windows and arrivals. How to use live maps and schedules so you don’t stand in the sun for hours on a hunch, and how to estimate the runway direction in use in advance, is explained in the guide Understanding the runway direction in use at an airport.
• Take thunderstorms seriously. Hot summer days often end with heat thunderstorms. An open field at the runway end with a metal ladder and tripod is then not a good place – more on that in the article Plane spotting in bad weather.
• Keep your basic kit up to date. What else belongs in the bag is covered in the gear checklist.

Conclusion

Summer is a strong spotting season, but it demands preparation. At the airport there is usually no shade, asphalt and light surfaces amplify heat and UV exposure, and the air shimmers over the aprons. If you start early in the morning, protect your head and skin consistently, drink enough and use the midday hours for a break, you go home with better pictures and without sunburn. Your gear will thank you if it sits in the shade between shots and never stays behind in a hot car. And when it gets cold again in winter, the guide Plane spotting in winter helps.
