Weather Calendars Direct to Primavera P6
WeatherWise exports weather calendars as .plf files that import directly into Primavera P6. No manual data entry. Activity-specific weather calendars aligned to your P6 programme structure.
What is Primavera P6?
Oracle Primavera P6 is the industry-standard project planning and scheduling software used by construction planners worldwide. It enables programme managers to create detailed work breakdown structures, define activity sequences with logic links, assign resources, and track progress against baseline schedules. P6 is the tool of choice for large-scale construction projects where critical path analysis, earned value management, and multi-project portfolio scheduling are essential.
Construction planners use P6 to build and maintain the master programme, perform what-if analysis on schedule scenarios, and produce progress reports for client and stakeholder review. However, P6 relies on manually created calendars to define working and non-working days — and most planners still build these calendars based on assumptions rather than data.
WeatherWise + Primavera P6
WeatherWise connects directly to your P6 programme by importing .xer and .xml files, reading your activity list and schedule structure. It then generates activity-specific weather calendars based on 30+ years of hyper-local climate data and exports them as .plf files — the native P6 calendar format. Planners can replace generic calendars with data-driven weather calendars in minutes, ensuring their P6 programmes reflect the actual probability of weather disruption at the project site.
Stop Manually Building P6 Weather Calendars
Creating weather calendars by hand in Primavera P6 is tedious and error-prone. Planners spend hours marking non-working days based on assumptions rather than data, and the result is calendars disconnected from the actual weather risk at the project site.
WeatherWise automates the entire process. Upload your P6 programme, define the weather conditions that prevent each activity from proceeding, and export precise .plf calendar files ready for direct import into P6.
How It Works
Four steps from your P6 programme to weather-adjusted calendars.
Upload P6 Programme
Import your .xer or .xml file from Primavera P6. WeatherWise reads your activities, durations, and project location automatically.
Set Weather Thresholds
Define the weather conditions that stop each activity. Wind limits for crane lifts, rainfall thresholds for earthworks, temperature bounds for concrete pours.
Generate Calendars
WeatherWise analyses 45+ years of climate data at your exact site coordinates and produces day-by-day working and non-working day predictions for every activity.
Export .plf to P6
Download .plf calendar files and import them directly into Primavera P6. Calendars align to your programme structure with no manual adjustments needed.
Key Features
Purpose-built for Primavera P6 users who need data-driven weather calendars.
Direct .plf Calendar Export
Export weather calendars as native P6 .plf files. Import directly into Primavera P6 resource calendars without any conversion or manual entry.
Activity-Specific Thresholds
Each activity in your P6 programme gets its own weather thresholds. Crane lifts, earthworks, and concrete pours each respond to different weather conditions.
P6 .xer/.xml Import
Upload your P6 programme in .xer or .xml format. WeatherWise reads your activity list, durations, and schedule structure automatically.
Automatic Calendar Alignment
Weather calendars align automatically to your P6 programme structure. Each calendar maps to the correct activity with the right date ranges and non-working periods.
Bulk Export
Generate and export .plf files for all activities in your programme at once. No need to create calendars one at a time when your programme has hundreds of activities.
Version Control
Track calendar iterations as your programme evolves. Regenerate and re-export calendars whenever forecasts change or your schedule is updated.
