Start Knowing.
Trade-specific weather intelligence for every construction operation. 14-day risk forecasting, historical data analysis, and standards-backed EOT evidence — all from a single location search.
Three Tools.
One Platform.

Built For The Work
You're Actually Doing
Generic weather apps tell you it's windy. Menlo Construction Weather tells you whether your crane should be operating, your concrete should be poured, or your welders should be on the job — and exactly why, referenced to the standards your contracts team will recognise.
Every advisory threshold is drawn from published industry standards. Not opinion. Not estimation. Defensible, documented operational limits.

Weather Claims.
Built On Data.
When weather delays your project, proving it is a different problem. Menlo Construction Weather gives you statistically benchmarked evidence — not site diary entries, not memory, not argument. Numbers your contracts team can defend.
No Programme Upload.
No Setup. Just Results.
The only construction weather tool that works for every contractor — regardless of planning maturity, software, or company size.
No programme upload. No P6 file. No Asta export. No integration setup. Type a city or allow GPS detection and you're working in under 10 seconds.
vs. enterprise tools that require programme upload before any analysis begins
Global coverage means the same tool works whether your project is in Auckland, Dubai, Singapore, London or Lagos. One subscription. Every site.
vs. tools built for single-market enterprise clients only
Every trade advisory threshold is drawn from published industry standards — AWS, BS EN, IMCA, OSHA, AS/NZS and more. Defensible decisions, not guesswork.
vs. generic weather apps with no construction context whatsoever
Built for individual contractors, site managers, planners and QS teams — not just tier-1 enterprise procurement. No lengthy onboarding. No sales calls required.
vs. enterprise platforms at prices that exclude most of the industry
The only tool with a built-in EOT Evidence Generator — statistically benchmarked against 5 years of historical data, exportable in Excel and PNG, ready for submission.
vs. weather apps that give you data but no analysis and no output
Forecast, historical data, and EOT analysis all from the same interface. No switching between tools. No manual lookups. No spreadsheet gymnastics.
vs. stitching together weather apps, Excel sheets and memory
