Green
Forecast conditions are within the configured advisory parameters for the selected operation. Normal planning controls still apply.
Daily trade planning for site managers
Know which operations are safe to run — before you mobilise the crew
A normal weather app tells you it will rain. Construction Weather tells you whether that rain — or wind, heat, cold or gust — stops the operation you have planned. Green, Amber and Red risk grading across more than 20 construction trade activities, with hourly detail and practical mitigation guidance.
Forecast information in a construction context
Every morning, site managers face the same decision: can this operation run today? Construction Weather answers that question with operation-specific data rather than a generic forecast. Select a trade and review a daily Green, Amber or Red advisory. Flagged days can be examined at hourly resolution so teams can plan the timing of work and consider mitigation measures before committing crew and plant.
- More than 20 trade-operation selections
- Daily operation-specific grading
- Hourly drill-down for flagged days
- Mitigation actions linked to risk level
- Threshold and standard references where configured
Understand each advisory level
Amber
Conditions may constrain the operation. Review timing, method, supervision and mitigation before proceeding.
Red
Conditions exceed a configured advisory threshold. Examine the hourly forecast and the project's safety and operational requirements.
Configurable alert thresholds
Every project has different operational limits. The notifications section lets you configure project-specific alert thresholds — wind speed, rainfall intensity, temperature, humidity — so alerts reflect your method statement or specification, not generic defaults.
Set your thresholds →Advisories are decision-support information. Site-specific risk assessment, manufacturer instructions, approved methods, competent-person judgement and applicable regulations remain controlling.
Operations covered
Weather affects different trades very differently. Each advisory is matched to the specific parameters relevant to the selected operation — not a generic forecast.
Crane and lifting
Wind speed and gusts — graded against manufacturer-specified limits for the crane type and configuration.
Scaffold erection
Wind and gust conditions relevant to erection and alteration of tube, system and special scaffolding.
Steel erection
Wind, gusts and rain — covering both crane-assisted placement and slip risk on structural steel sections.
Concrete placement
Rainfall intensity, temperature (min/max), wind and humidity — covering placement, finishing and curing.
Structural and pipeline welding
Wind speed, humidity, dew point and temperature — key parameters for WPS compliance under API 1104, ASME, AWS D1.1 and similar codes.
Painting and applied coatings
Humidity, dew point spread, temperature, rainfall and wind — covering the application window for industrial and protective coatings.
Blasting and surface preparation
Humidity and dew point — critical for achieving and maintaining blast-cleaned surfaces before coating application.
Roofing and waterproofing
Rain, wind and temperature — covering membrane installation, lap sealing and adhesive application conditions.
Cladding and curtain walling
Wind and rain — covering panel handling and installation conditions for facade systems.
Masonry and brickwork
Rain, frost and temperature — covering mortar setting conditions and protection requirements.
Earthworks and excavation
Rainfall intensity and frost — covering trafficability, compaction and slope stability conditions.
Road surfacing and asphalt
Ambient and substrate temperature, rainfall and wind — covering placement and compaction window conditions.
External render and plastering
Rain, frost, temperature and wind — covering application, drying and curing conditions for external plaster systems.
Piling operations
Rainfall and wind — covering trafficability for plant movement and wind sensitivity for tall rig configurations.
Glazing and facade installation
Wind and gusts — covering suction-lift handling limits and sealant application conditions.
Timber framing and joinery
Rain, humidity and wind — covering moisture exposure risk and handling conditions for structural timber and roof trusses.
Site-level spatial context
See the wind conditions around your site — not just a number
The Local Conditions map shows animated wind-flow across the area surrounding your pinned site location. Where a forecast gives you a wind speed figure, the map shows you the direction, spatial variation and terrain influence shaping conditions on the ground. That context helps teams judge whether a gusting southerly is funnelling through a local gap or whether conditions across the site are broadly consistent.

- Temperature readout at your pinned location
- Spatial view of conditions across the surrounding area
- Snapshot export for site records and method-statement review
Historical context
Compare forecast with historical norms
Where historical records are available for the selected location, the platform can show how forecast conditions compare with the five- and ten-year average for that time of year — helping teams assess whether conditions are unusually severe or broadly expected.

Common Questions
Trade Advisories FAQ
How many construction trade operations does the advisory feature cover?
The advisories feature covers more than 20 construction trade operations, including crane and lifting, scaffold erection, steel erection, concrete placement, structural and pipeline welding, painting and applied coatings, blasting and surface preparation, roofing and waterproofing, cladding and curtain walling, masonry and brickwork, earthworks and excavation, road surfacing and asphalt, external render and plastering, piling, glazing and facade installation, and timber framing and joinery. Each operation is matched to the weather parameters relevant to that trade.
What do Green, Amber and Red advisory levels mean?
Green means forecast conditions are within the configured advisory parameters for the selected operation — normal planning controls still apply. Amber means conditions may constrain the operation; teams should review timing, method, supervision and mitigation before proceeding. Red means conditions exceed a configured advisory threshold; teams should examine the hourly forecast and the project's safety and operational requirements before committing crew and plant. Advisories are decision-support information; site-specific risk assessment and competent-person judgement remain controlling.
Can I customise the weather thresholds to match my project specifications?
Yes. The notifications section of the platform allows you to configure project-specific alert thresholds for wind speed, rainfall intensity, temperature, humidity and dew point. This means alerts can reflect your crane manufacturer's limits, welding procedure specification, coating product data sheet or contract method statement rather than generic defaults.
How far ahead does the construction weather forecast go?
The trade advisory forecast covers 14 days ahead. The first three days are generally reliable. Days 8–14 are indicative and should not be relied upon for precise operational decisions — they are useful for advance programme planning and early awareness of potentially significant conditions. A separate Forecast Lookahead feature extends the outlook further for tender planning and programme purposes.
Is a construction weather advisory the same as a general weather forecast?
No. A general weather forecast tells you it will rain. A Construction Weather advisory tells you whether that rain — or wind, frost, heat, humidity or gust — stops the specific operation you have planned. Each advisory is matched to the parameters relevant to a selected trade, not to a generic weather description. The platform applies the same threshold logic used in construction contract adverse weather clauses, making it relevant for site planning and contractual record-keeping rather than general weather awareness.
