For outdoor equipment in Dubai, heat dominates: a July monthly mean of 36.4 C in the CEY10 representative year (ERA5-Land 2015-2024, one 0.25° grid cell). Monthly mean dew points reach 22.4 C in July, so cooled surfaces can still be wetted. Screening values for durability planning, not weather or travel information.
No Climetry Exposure Class, corrosion screening, condensation or humidity class is shown for Dubai: the inputs and calculation behind the previously published classes could not be traced in the current release evidence. Heat is shown as the primary stressor from the monthly temperature profile; other stressor rankings are not assessed.
CE classes describe overall environmental severity and are not equivalent to ISO corrosivity classes.
The values on this page describe one city grid point. Distance to the coast and the exact location change chloride, humidity and heat exposure, so the next step is an analysis at your own coordinates.
Extreme heat, marine influence and dust exposure create unique durability challenges for products deployed outdoors in Dubai.
Humidity exposure is lower than in tropical sites, but summer dew points and cooled surfaces can still matter for enclosures, connectors and power electronics.
Dubai is especially relevant for solar, BESS and telecom equipment because thermal stress and atmospheric contamination can act together.
Climetry-derived indicators summarize environmental severity. ISO-derived indicators estimate material-related atmospheric corrosivity for metals such as carbon steel, zinc, copper and aluminum.

Hours with RH of at least 80 % in the CEY10 representative year at one ERA5-Land 0.25° grid cell. Screening value; see the validation note below.
Hours with RH of at least 90 % in the same CEY10 representative year and grid cell. Screening value; see the validation note below.
Heat stress with coastal environmental modifiers.
Validation limit: Dubai International Airport recorded 219-400 h per year with RH of at least 80 % (and 19-73 h at 90 % or more) in 2015-2024. The airport and the grid cell are different locations, and representative-year exposure hours are a screening value, not a validated output. They are not corrected here. Scientific validation
Monthly mean values of the core thermodynamic variables. Only the monthly means are shown, without a spread or range.
Monthly means of the CEY10 representative year: real months selected from ERA5-Land 2015-2024, at the ERA5-Land 0.25° land grid cell nearest the city coordinates. One grid-cell value, not a station measurement.
Humidity is episodic but coastal peaks can still matter.
Strong summer heat load dominates thermal qualification.
Absolute humidity rises sharply in the hot coastal season.
Dew point peaks in summer, when cooling surfaces can face condensation risk.
Monthly mean dew points reach 22.4 C in July in this representative year. Whether a specific cooled surface gets wet depends on its own temperature. Check a surface against the dew point
These figures are calculated from the local hourly Climetry Environmental Year and translate thermodynamic climate data into engineering-readable duration, cycle and moisture-risk views.
Dubai's 1 C temperature-duration histogram is calculated from the selected hourly CEY10 source months. It shows how long products experience each outdoor temperature band during the representative year.
The RH duration histogram translates relative humidity into annual exposure hours. It supports moisture-sensitive electronics, coating, connector and enclosure screening.
The joint duration heatmap shows which temperature and humidity combinations occur together. This is more useful for durability screening than separate annual averages.
The psychrometric density view connects dry-bulb temperature with absolute humidity and helps identify moisture-rich operating conditions and drying limitations.
The percentile profile summarizes the representative spread of temperature, dew point, relative humidity, absolute humidity and dew-point margin.
The selected high-risk week highlights periods with elevated humidity, absolute humidity and small dew-point spread. It is a screening view for condensation and moisture-ingress relevance.
Daily temperature-cycle statistics provide engineering input for thermomechanical reliability assessments, enclosure breathing and gasket stress screening.
The cold-week temperature histogram is useful for heating-load screening in temperate and cold climates. In tropical climates it confirms low heating-design relevance.
CE classes summarize humidity, condensation potential, marine influence, pollution context and thermal exposure. They are not ISO 9223 corrosivity classes.
It is useful for identifying persistent moisture exposure relevant to electronics, coatings, connectors, enclosures and atmospheric corrosion screening.
It is derived from temperature, dew point and humidity context. It is a screening indicator, not a measurement on a specific product surface.
Atmospheric screening (CAMS marine aerosol and pollution scores, chloride proxy, MERRA-2 sulfate), UV and ozone profiles and the exposure fingerprint scores are not shown for Dubai: their source files could not be traced in the current release evidence. They will return once their dataset, period and grid are documented.
Exposure hours (RH80/RH90) and the hourly CEY engineering figures (duration, histogram and percentile diagrams) on this page come from the CEY10 representative year: real months selected from ERA5-Land 2015-2024 at one 0.25° grid cell. The monthly profile charts state their own data basis above them.
The station comparison below is a separate 2025 pilot. It compares monthly values of ERA5, the global reanalysis rather than ERA5-Land, at the nearest grid point with Meteostat airport observations: 12 monthly values per station. It does not validate the representative year, its exposure hours, CE classes or corrosion screening.
For some coastal cities, including Dubai, Mumbai, Seattle and Singapore, the representative-year exposure hours lie outside the annual range observed at the airport station. Broader station comparisons of ERA5-Land and CEY10 are described on the scientific validation page.
ERA5 (the global reanalysis, nearest grid point) monthly means for 2025 compared with Meteostat observations at Dubai International Airport (OMDB): 12 monthly values per variable. Bias is ERA5 minus station.
Mean bias −1.47 °C
Mean bias +1.85 °C

The full report combines climate classification, corrosion screening, condensation exposure, RH80/RH90 hours, marine context, monthly profiles, and reliability implications.
RH80/RH90: Validation limit: Dubai International Airport recorded 219-400 h per year with RH of at least 80 % (and 19-73 h at 90 % or more) in 2015-2024. The airport and the grid cell are different locations, and representative-year exposure hours are a screening value, not a validated output. They are not corrected here.
High humidity and condensation exposure may result in a severe Climetry Exposure Class even if atmospheric metal corrosivity remains moderate. CE classes indicate environmental severity and qualification relevance, not failure probability.
Analyze any location worldwide and compare humidity, condensation and environmental severity.
A Climetry Exposure Class describes overall environmental severity for durability screening. For Dubai the inputs behind the previously published class could not be traced, so no class is shown until they are documented. A site analysis computes the class for your own coordinates.
No. The page provides environmental exposure screening. Corrosion indicators are engineering screening outputs, not failure probability and not a product-specific lifetime prediction.
Exposure hours and the hourly CEY engineering figures (duration, histogram and percentile diagrams) come from the CEY10 representative year: real months selected from ERA5-Land 2015-2024 at one 0.25° grid cell. A separate 2025 pilot compared ERA5 monthly values with airport observations (12 monthly values per station); it does not validate the representative year or its exposure hours. For some coastal cities the representative-year exposure hours lie outside the range observed at the airport. The monthly profile charts state their own data basis above them. Treat the values as screening values.
CE classes describe overall environmental severity. ISO 9223 corrosivity classes describe material-related atmospheric corrosivity categories. They are related but not equivalent.
Temperature, dew point and pressure from ERA5-Land, assembled into the CEY10 representative year (2015-2024), are used to derive relative humidity, absolute humidity and exposure hours. Other layers name their own source and period where they are shown.
