Why Do We Perform Temperature Mapping in Warehouses During Winter and Summer?

Oct 6 / Chris Maughan



Maintaining the correct temperature and humidity for life sciences products is critical. Regular temperature mapping ensures that your warehouse stays compliant and protects product integrity.


In controlled environments like incubators, refrigerators, and freezers, insulation and internal temperature controls help maintain stable conditions. Temperature variations usually only occur due to door openings or equipment failures, which are easily detected by monitoring systems.

Warehouses, however, are far more complex environments. They’re larger, and temperature fluctuations are influenced by factors like air circulation, the structure’s insulation, and even the number of open doors.

The biggest influence on temperature and humidity inside warehouses is the external climate. Seasonal changes—especially the extremes of winter and summer—can drastically affect internal temperatures. This is why temperature mapping is typically conducted during the winter and summer months.

When Should You Perform Temperature and Humidity Mapping on Warehouses?

For new warehouses, it’s important to map temperatures during both winter and summer. This helps you understand the temperature range across all storage areas during these extreme conditions. Winter and summer are defined as:

  • Winter: 1st December to 28th February (or 29th February during leap years)

  • Summer: 1st June to 31st August

5 Steps for Effective Warehouse Temperature Mapping

Follow these steps to ensure your warehouse temperature mapping is accurate and smooth:

  1. Physically Identify Sensor Locations: Ensure all critical areas are mapped, including temporary set-down zones, and the minimum and maximum height storage areas. (See our blog post Warehouse Sensor Locations or watch our webinar Warehouse Mapping -Sensor Locations )

  2. Parameter Check: Are you only measuring temperature, or is humidity also a critical factor? Define the parameters that need mapping.
  3. Sensor Selection: Choose sensors that are calibrated, cover the expected temperature range, have suitable accuracy, and can log data at appropriate intervals.
  4. Protocol Preparation: Create a detailed protocol outlining the testing requirements, sensor locations, calibration certificates, logging intervals, and any other critical factors.
  5. Execute the Mapping: After preparation, it’s time to implement the mapping. Ensure the process follows the defined protocol to guarantee accurate results.
