Houston represents a humid Gulf Coast environment where moisture, heat and industrial coastal context can affect field reliability.
Analyze HoustonHumidity is the primary stressor. Heat and industrial coast is the secondary driver for reliability and field durability decisions.
CE classes describe overall environmental severity and are not equivalent to ISO corrosivity classes.
A normalized 0-100 matrix showing which exposure mechanisms dominate the deployment environment. Scores describe environmental load intensity, not failure probability.
Gulf Coast humidity creates long periods of elevated moisture exposure that can affect electronics, battery systems and outdoor equipment.
The combination of warm temperatures, high dew points and regional industrial context makes Houston a practical stress case for infrastructure operators and product durability teams.
For qualification planning, Houston is useful because it is not purely tropical, but it can still create severe humidity-led exposure for outdoor assets.
Climetry-derived indicators summarize environmental severity. ISO-derived indicators estimate material-related atmospheric corrosivity for metals such as carbon steel, zinc, copper and aluminum.
High moisture load with heat and coastal-industrial context.
Humidity and Gulf Coast influence increase exposure severity.
Moist overnight and seasonal transitions matter.
CEY10 long annual wet-hour exposure window.
CEY10 frequent high-humidity stress periods.
Warm, moist, and seasonally storm-influenced.
Preview profiles show monthly min-max envelopes, P10-P90 percentile bands, and monthly means for the core thermodynamic variables.
High humidity persists across seasons, with warm-season moisture stress.
Summer heat combines with humidity for enclosure and electronics stress.
Absolute humidity is high during the long warm season.
Dew point rises strongly in summer, increasing condensation relevance.
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.
Houston'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.
Houston values are sampled from the Climetry Gulf Coast USA 1.5 km atmospheric transport overlays using 32 wind sectors and corrected diffusion. Chloride has a local NADP-based calibration signal; SOx is shown as a screening field only because the Gulf Coast rank correlation is not significant.
Annual mean sampled at Houston from the Gulf Coast USA 1.5 km atmospheric transport grid with 32 wind sectors.
Gulf Coast chloride calibration: R2=0.852 on the calibration set, rho=0.891, n=10 against NADP wet-deposition stations. Small validation split is not used as evidence.
Houston is close enough to the Gulf Coast corridor for marine chloride screening to remain relevant.
Sampled at Houston from the Gulf Coast SOx transport screening grid with 32 wind sectors.
EPA AirData comparison for Gulf Coast SOx is not rank-significant (rho=0.092, p=0.545, n=46). Use SOx as screening context only.
Approximate ISO 9223-style input categories: time of wetness, chloride deposition and sulphur pollution screening input.
ISO-derived screening indicator: high humidity plus Gulf Coast chloride and SOx context place Houston in a high screening band.
ISO-derived screening indicator: chloride-sensitive but interpreted as screening-level, not certified site classification.
For Houston, wet hours and Gulf Coast chloride context dominate over pure temperature exposure.
Monthly profiles are derived from the Gulf Coast USA 2015-2024 atmospheric transport model at the Houston grid cell. Chloride is calibrated with caveats; SOx magnitude remains uncalibrated and should be interpreted as industrial-source screening context.
Monthly chloride screening estimates are normalized to the same annual grid-cell mean shown above. Houston shows strong Gulf Coast chloride exposure despite being inland from the immediate shoreline.
The SOx screening index is high at Houston, but the regional SOx validation did not show a significant rank correlation. Treat this as source-context screening, not calibrated concentration.
The environmental indicators presented on this page are derived from ERA5 climate data.
ERA5 thermodynamic variables have been compared against long-term airport weather station observations across multiple climate regions.
The comparison demonstrates good agreement between ERA5 and measured environmental conditions.
These comparisons evaluate long-term environmental representativeness and not individual weather events.
Monthly thermodynamic comparison against Houston Intercontinental (KIAH) weather observations for 2025.
The full report combines climate classification, corrosion screening, condensation exposure, RH80/RH90 hours, marine context, monthly profiles, and reliability implications.
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.
CE-4 is a Climetry Exposure Class. It describes overall environmental severity for durability screening and qualification support at this location.
No. The page provides environmental exposure screening. Corrosion indicators are engineering screening outputs, not failure probability and not a product-specific lifetime prediction.
The indicators are derived from ERA5 climate data. ERA5 thermodynamic variables have been compared against representative airport weather observations and show good monthly agreement for temperature, dew point and relative humidity.
CE classes describe overall environmental severity. ISO 9223 corrosivity classes describe material-related atmospheric corrosivity categories. They are related but not equivalent.
Climetry uses ERA5 temperature, dew point and pressure fields to derive relative humidity, absolute humidity and environmental exposure indicators for engineering interpretation.
