How to protect your tech from humidity on Phangan (I learned this the hard way)

I'm going to start with the worst part: in my first rainy season on Phangan, I killed a MacBook Pro and a Sony mirrorless camera within six weeks of each other. Not dropped, not stolen — just quietly destroyed by humidity. 😅

So consider this the guide I wish someone had given me before I moved here. Humidity on Phangan during rainy season (roughly June–October) regularly sits at 85–95%. That's not "it feels muggy" — that's "your electronics are slowly dying every single day."

What actually happens to your gear

The damage isn't dramatic. There's no moment where your laptop explodes or your camera stops working instantly. It's gradual:

Charging ports and headphone jacks oxidize and stop making good contact
Camera lenses develop fungus (it starts as tiny dots you barely notice, then grows and etches the glass permanently)
Laptop motherboards develop corrosion that causes weird, intermittent failures
Speakers get a permanent crackle
Keyboards start sticking

By the time you notice, significant damage is already done. The camera I lost had tiny mold spots I spotted on the lens element — by then it needed professional cleaning that cost more than the camera was worth.

The simple fix: silica gel, everywhere

Buy a big bag of silica gel sachets from any pharmacy or hardware store in Thong Sala. They're cheap and they work. Put them:

In your bag, next to your laptop
In any camera case or bag
In a sealed container with your spare electronics
In your wardrobe if you have sensitive equipment stored there

When the sachets turn dark (usually color-indicating ones go from orange to green, or blue to pink), they're saturated. Pop them in an oven at 120°C for an hour and they regenerate. I do this about once a month in rainy season.

Camera and lens care — the critical stuff

This is where I'd focus most of your attention. Lens fungus is irreversible without professional cleaning, and on Phangan that means a trip to Surat Thani or shipping to Bangkok.

Store cameras in an airtight box or dry cabinet with silica gel
After being at the beach — especially in salty sea air — wipe down the camera body with a dry cloth before putting it away
Periodically take lenses off the camera body and let them air in sunlight. UV light kills fungus spores
Never put a camera away in a bag while it's still warm from use — let it cool first, condensation is your enemy

Laptop survival tips

The main thing is avoiding condensation, which happens when you move from a hot environment to a cold air-conditioned room (or vice versa).

Keep your laptop in a bag with silica gel when you're not using it
If you're moving from outside (hot) to inside (AC), let the laptop sit in the bag for 15–20 minutes before opening it — let it temperature-equalize
Periodically clean the ports with a dry toothbrush or compressed air
If your charging port feels "loose" or unreliable, get it looked at before it gets worse — the repair shop in Thong Sala can usually fix oxidized connectors

The investment worth making

If you're staying for more than a month, buy a dry cabinet. They're basically a sealed box with an electronic humidity controller inside. You can find them online and shipped to Phangan for 1,500–3,000 baht. After losing my camera and laptop, I bought one immediately. Haven't had a humidity problem since.

It's the one piece of equipment I recommend to every digital nomad who moves here. Your laptop cost ten times as much — protect it properly.
