Keeping Your Electronics Dry in Thailand's Humidity

To protect your gear from Thailand's 80%+ humidity, use airtight dry bags with silica gel packets and avoid moving your devices rapidly between high-AC rooms and the humid outdoors. This temperature shock causes internal condensation, which is the primary cause of circuit board failure.

  1. Bag your gear. Place laptops, cameras, and lenses in dedicated dry bags or heavy-duty Ziploc bags. Squeeze as much air out as possible before sealing them.
  2. Add desiccant. Drop 2-3 silica gel packets into every sealed bag. Replace these every 30 days, or sooner if they turn from blue/orange to pink/transparent.
  3. Manage the temperature transition. When leaving a cold AC room (20°C) for the humid outdoors (32°C), keep your device inside your closed bag for 20 minutes. This allows the internal temperature to equalize slowly, preventing condensation on the lens or motherboard.
  4. Avoid direct charging in the open. If you are in a coastal area, charge your devices in an area with some airflow or a dehumidifier if available, as salt air combined with humidity accelerates corrosion.
Should I bring a dehumidifier for my hotel room?
No. Most hotels in Thailand have excellent AC units with a 'Dry' mode (usually indicated by a water drop icon). Set your unit to this mode to pull moisture from the air while you sleep.
What if my phone gets condensation behind the screen?
Turn it off immediately. Place it in a bag of fresh silica gel packets (not rice, which introduces dust and starch) for 24 hours. Do not use a hair dryer, as the heat can damage screen seals.
