Festival Season Is Here: How to Protect Your Instruments in the Great Outdoors

It's festival season — the sun is shining (or the rain is pouring), the stages are set, and musicians everywhere are gearing up for outdoor gigs, open-air concerts, and summer festivals. But while you're soaking up the atmosphere, your instruments are battling the elements. Temperature changes, humidity fluctuations, direct sunlight, and unpredictable British weather can all play havoc with your gear.

Whether you play guitar, brass, woodwind, orchestral strings, drums, or ukulele, here's everything you need to know about protecting your instruments outdoors this festival season.

🌡️ Temperature: The Silent Instrument Killer

How Temperature Affects Your Instruments

Both wood and metal react to temperature changes — and outdoor environments can swing wildly between scorching midday heat and cool evening air.

• Wooden instruments (guitars, violins, cellos, clarinets, oboes) expand and contract with temperature shifts. This affects tuning stability, action height, and can even cause cracking or warping in extreme cases.
• Metal instruments (trumpets, trombones, saxophones, flutes) expand when hot and contract when cold. This directly affects intonation and pitch — a brass instrument left in direct sunlight can go noticeably sharp.
• Drum heads tighten in the cold and loosen in the heat, changing your tone and response.
• Keyboards and electronic equipment can overheat, causing damage to circuits and batteries.

Tips for Managing Temperature

1. Keep instruments in the shade as much as possible — never leave them in direct sunlight on stage or backstage.
2. Use light-coloured cases and bags that reflect heat rather than absorb it.
3. Avoid leaving instruments in vehicles — a car boot in summer can reach 60°C+, enough to melt glue joints and warp wood.
4. Allow gradual acclimatisation — don't take a cold instrument straight into a hot stage environment (more on this below).

💧 Humidity: Wood's Worst Enemy

How Humidity Affects Instruments

While metal instruments are largely unaffected by moisture in the air, wooden instruments are incredibly sensitive to humidity changes. Festival fields can go from bone-dry dusty conditions to damp and misty in hours.

• Low humidity causes wood to shrink — leading to sharp fret ends on guitars, cracks in violin tops, and loose joints on clarinets and oboes.
• High humidity causes wood to swell — raising action on guitars, making keys stick on woodwind instruments, and dulling the resonance of orchestral instruments.
• Rapid humidity changes are the most dangerous — they create uneven stress in the wood that can cause irreversible damage.

Tips for Managing Humidity

1. Keep instruments in their cases when not playing — cases create a microclimate buffer.
2. Use a case humidifier or dehumidifier depending on conditions.
3. Wipe down wooden instruments after playing to remove moisture from sweat and condensation.
4. Monitor conditions — a small hygrometer in your case costs very little but can save expensive repairs.

🎯 The Golden Rule: Acclimatise Before You Play

One of the most important things you can do at any outdoor gig or festival is let your instrument acclimatise to the environment before performing.

How to Acclimatise Properly

1. Arrive early and take your instrument to the performance area.
2. Open your case and leave it open — let the instrument gradually adjust to the ambient temperature and humidity. Aim for at least 15–30 minutes.
3. Don't force it — if your instrument has been in a cold van overnight and the stage is in blazing sunshine, give it extra time.
4. Keep it in the shade while acclimatising — you want it to adjust to the air temperature, not bake in direct sunlight.

This simple step can prevent cracking, warping, and will make your tuning far more stable when you hit the stage.

🎸 Tuning and Retuning: Don't Skip This Step!

Outdoor conditions mean your tuning will drift. It's not a question of if, but when and how much.

Tuning Tips for Festival Musicians

• Tune up after acclimatising — there's no point tuning a cold instrument that's about to warm up and go sharp.
• Retune just before you go on stage — even 10 minutes of waiting in different conditions can shift your pitch.
• Carry a reliable tuner — clip-on tuners work brilliantly in noisy festival environments where phone apps struggle.
• Check tuning between songs — especially if you're in direct sunlight or the weather is changing.
• Brass and woodwind players: warm up your instrument with long tones and check your tuning slide/barrel — you'll likely need to adjust more than usual.
• String players: expect to retune frequently. Fresh strings will stretch more in the heat, so change them a few days before the gig, not the day of.
• Drummers: bring a drum key and check tension in advance and just before your set if possible — drum heads respond dramatically to temperature.

🎷 Instrument-Specific Tips for Outdoor Playing

Guitars & Ukuleles

• Keep in a hard case when not playing
• Loosen strings slightly if storing in extreme heat for long periods
• Watch for neck relief changes — you may need a truss rod tweak after festival season
• Use a stand in the shade rather than leaning against hot surfaces
• Browse our guitar collection and ukulele range

Brass Instruments (Trumpets, Trombones, Tubas, French Horns)

• Metal heats up fast in sunlight — a brass instrument left on a stand in the sun can become too hot to hold
• Valves and slides may stick or become sluggish — keep valve oil and slide grease handy (it will flow more freely in the heat and may need more frequent top-ups)
• Condensation builds up faster in humid conditions — empty water keys frequently
• Wipe down after playing to prevent tarnishing from sweat and moisture

Woodwind Instruments (Clarinets, Oboes, Flutes, Saxophones)

• Wooden woodwind instruments are extremely vulnerable to cracking from rapid temperature/humidity changes
• Swab out frequently — moisture from breath combined with outdoor humidity accelerates pad deterioration
• Cork joints can swell or shrink — carry cork grease
• Metal flutes and saxophones will go sharp in the heat — be ready to adjust

Orchestral Strings (Violins, Violas, Cellos, Double Basses)

• These are among the most vulnerable instruments outdoors — browse our orchestral collection
• Bow hair loosens in humidity and tightens in dry conditions — adjust accordingly
• Pegs may slip more in humidity or seize in dry conditions
• Never leave in direct sunlight — varnish can soften and become damaged
• Carry spare strings — they're more likely to break in extreme conditions

Keyboards & Electronic Instruments

• Keep keyboards covered when not in use
• Protect from direct sunlight and rain
• Ensure adequate ventilation — overheating is a real risk
• Use quality cables and connectors rated for outdoor use
• Consider a canopy or gazebo for your setup

Drums & Percussion

• Drum heads are hugely affected by temperature — tune on site, not at home
• Metal hardware expands in heat — wing nuts and tension rods may need adjustment
• Keep cymbals out of direct sunlight to avoid warping
• Use stands on solid ground — soft festival turf can cause instability

🎤 Protect Your Most Important Instrument: Your Voice

Your voice is an instrument too — and it's just as vulnerable to the outdoor festival environment as any guitar or trumpet. Here's how to keep your vocals in top shape for outdoor performances.

Hydration Is Everything

• Drink plenty of water throughout the day — not just before you perform. Your vocal cords need to stay lubricated to function properly.
• Avoid alcohol and caffeine in the hours before your set — both are diuretics that dehydrate your vocal cords.
• Sip warm (not hot) water with a little honey if conditions are dry or dusty — festival fields kick up a lot of dust that irritates the throat.
• Avoid ice-cold drinks right before singing — they can tighten the muscles around your larynx.

Warm Up Properly

• Do vocal warm-ups before every performance — lip trills, humming, gentle scales, and sirens help prepare your voice for the demands of a live set.
• Start gently — don't go from silence to belting. Build up gradually over 10–15 minutes.
• Cool down afterwards too — gentle humming and sighing after an intense set helps your vocal cords recover.

Save Your Voice for the Stage

• Don't shout over the crowd between sets or while socialising backstage. It's tempting to yell over festival noise, but this is one of the fastest ways to damage your voice before a performance.
• Use a good microphone and proper sound reinforcement so you don't have to strain to be heard. A quality mic with good gain means you can sing at a comfortable level and still cut through the mix.
• Stay close to the mic rather than pulling back and pushing harder — good microphone technique saves voices.
• Rest your voice between sets — avoid talking unnecessarily and perhaps communicate with gestures or texts where possible.

Outdoor-Specific Vocal Challenges

• Dust and dry air can irritate your throat — consider a scarf or buff over your mouth when walking around the festival site.
• Cold evening air can tighten your vocal cords — warm up again if there's a long gap between soundcheck and performance.
• Wind can make you push harder to hear yourself — trust your monitors and your microphone rather than forcing volume.
• Humidity can actually help your voice — moist air keeps vocal cords supple, so humid days are often easier on singers than dry, hot ones.

👂 Hearing Protection: Look After Your Ears

Your hearing is irreplaceable, and festival environments are dangerously loud. Prolonged exposure to high volumes causes permanent, cumulative damage — and once it's gone, it doesn't come back.

The Risks

• Sustained exposure above 85dB causes hearing damage — a typical festival stage runs at 100–110dB or more.
• Tinnitus (persistent ringing in the ears) affects a huge number of professional musicians — and it's entirely preventable.
• Hearing loss is gradual — you won't notice it happening until significant damage is done.

Hearing Protection Tips for Musicians

• Invest in musician's earplugs — these are designed to reduce volume evenly across all frequencies, so music still sounds natural, just quieter. They're a world apart from cheap foam plugs that muffle everything.
• Use in-ear monitors (IEMs) instead of relying on loud stage wedge monitors. IEMs let you hear a clear mix at a safe volume, reducing the need for deafening stage levels.
• Good microphone technique and quality sound reinforcement mean the overall stage volume can be lower — benefiting everyone's ears.
• Take breaks from loud environments — step away from the stage between sets and give your ears time to recover.
• Watch for warning signs — if you experience ringing, muffled hearing, or a feeling of fullness in your ears after a performance, you've been exposed to too much volume.

Protecting Your Ears Off-Stage Too

• Be mindful when watching other acts — stand further back from the PA stacks or wear your earplugs.
• Limit headphone use between performances — your ears need rest, not more stimulation.
• Get regular hearing checks — especially if you perform frequently at festivals and loud venues.
