Protecting Electronics from Caribbean Humidity
Keep your gear in airtight dry bags with silica gel packets and never move devices quickly between air-conditioned rooms and the humid outdoors. This rapid temperature shift creates internal condensation that kills circuit boards.
- Buy high-quality desiccant packs. Purchase a 50-pack of rechargeable or indicator-style silica gel packets. Do not rely on the tiny, non-indicating packets that come in shoeboxes; they saturate too quickly.
- Seal your storage. Use heavy-duty, sealable dry bags (IP67 rated) for your primary camera gear and laptop. Place 2–3 silica packets at the bottom of the bag and seal it completely before going outside.
- Manage temperature transitions. When leaving an air-conditioned hotel (typically 68°F/20°C) to go into the humid heat (85°F/29°C), place your camera bag in an unsealed plastic bag for 30 minutes. This allows the device to reach ambient temperature slowly without pulling moisture from the air onto the cold internal parts.
- Daily maintenance. At the end of the day, wipe down the exterior of all electronics with a microfiber cloth to remove salt air residue, which is corrosive and attracts moisture.
- Can I just use a regular backpack?
- No. Regular fabric backpacks provide zero moisture protection. You must use a dedicated dry bag or a hard-shell case with a rubber gasket seal.
- What happens if condensation forms on my lens?
- Stop shooting immediately. Place the camera in a bag with fresh silica gel and leave it in a cool, dry place for at least 4 hours. Do not force it dry with a hair dryer, as the heat can damage rubber gaskets.
