Industry use case
Construction
Weather-proof your programme before ground is broken.
Planners and contractors use PastClimate to build realistic schedules and to document weather-related delay against an independent, multi-year record.
How PastClimate helps
Schedule risk
See typical rainy and windy days by month before you commit to a programme.
Pour & finishing windows
Find the climatological window when temperatures actually suit concrete cure and coatings.
Delay & EOT claims
Compare a disputed date against the 10+ year baseline and the wettest/windiest days on record.
Site safety limits
Baseline average and peak wind speeds to set safe crane-operating thresholds.
The report
Weather Delay & Baseline Report
Contractors and PMs building an EOT claim; planners quantifying weather-day risk before bidding a schedule.

Rain odds, sample pour date (Jul 15)
sample date — any date on the calendar works
In your report
- 10+ year baseline ("normal") weather for the site's month and location — temperature, rainfall, wind and humidity
- Hottest, coldest, wettest and windiest day on file, with the date each occurred — reference evidence for a delay claim
- Climatological pour & finishing window — the average day-of-year span when overnight temperatures cross a chosen threshold
- Chance of rain on a specific milestone date (e.g. a pour day), from the multi-year daily climatology
- Monthly wind and rainfall normals to flag typically wet or high-wind months before you commit to a programme
Coming soon
- Day-by-day rain, wind and temperature for a specific disputed delay window, checked against the baseline (needs the raw daily series, not yet built)
- Per-year, configurable-threshold counts of weather-lost days (e.g. wind over a chosen crane limit, rain over a chosen depth) — same raw-daily-series dependency
- Per-year pour/finishing-window and safety-limit detection (today's window uses the multi-year climatological average day, not each individual year)
