Weather Calendars for Microsoft Project
WeatherWise exports weather calendars compatible with Microsoft Project. Apply weather-adjusted calendars to activities in your MS Project programme.
What is Microsoft Project?
Microsoft Project is the world's most widely used project scheduling tool, providing construction planners with Gantt chart scheduling, resource management, critical path analysis, and progress tracking. Available as a desktop application and through the cloud-based Project for the web, MS Project is the entry point for many organisations into formal programme management and construction planning.
Construction planners use Microsoft Project to develop project schedules, define task dependencies, allocate resources, and produce progress reports for stakeholders. Its familiar interface and integration with the Microsoft ecosystem make it accessible to teams of all sizes. However, its built-in calendar system requires manual configuration of non-working days and has no native weather intelligence capability.
WeatherWise + Microsoft Project
WeatherWise exports weather calendars in formats compatible with Microsoft Project. Planners can import activity-specific weather calendars generated from 30+ years of location-specific climate data directly into their MS Project schedules. This gives teams using Microsoft Project the same data-driven weather intelligence that was previously only available to P6 and Asta users — transforming generic calendar assumptions into evidence-based working day calculations.
Data-Driven Weather Calendars for MS Project Users
Microsoft Project is one of the most widely used scheduling tools in construction. Yet weather allowances in MS Project programmes are typically built on flat percentage assumptions that ignore site-specific weather patterns and activity-level sensitivities.
WeatherWise changes this. Upload your .mpp file, define the weather conditions that stop each task, and export precise weather calendars back into MS Project. Every task gets a calendar grounded in 45+ years of real climate data at your exact project site.
How It Works
Four steps from your MS Project file to weather-adjusted calendars.
Upload MS Project File
Import your .mpp file directly into WeatherWise. Your tasks, durations, dependencies, and project location are read automatically from the file.
Set Weather Thresholds
Define what weather conditions stop each task. Wind speed limits for lifting, rainfall thresholds for excavation, temperature bounds for paving. Use defaults or set your own.
Generate Calendars
WeatherWise analyses 45+ years of ERA-5 climate data at your exact site location and generates day-by-day calendars showing working vs. non-working days for every task.
Export & Import
Download the generated calendar file and import it into MS Project's calendar manager. Assign weather calendars to the relevant tasks in your programme.
Key Features
Built for Microsoft Project users who need accurate weather calendars.
MS Project Compatible Export
Export weather calendars in a format compatible with Microsoft Project. Import into MS Project's calendar manager and assign to tasks in your programme.
.mpp File Import
Upload your .mpp file directly to WeatherWise. Tasks, durations, dependencies, and project structure are read automatically without manual re-entry.
Activity-Specific Calendars
Each task in your MS Project programme gets its own weather calendar. Different tasks respond to different weather conditions, and the calendars reflect this precisely.
Calendar Alignment
Weather calendars align to your MS Project programme structure. Non-working weather days integrate alongside existing non-working periods like weekends and holidays.
Bulk Export
Generate and export calendars for all tasks in your programme at once. No need to create weather calendars one task at a time, even on large programmes.
Update Capability
Regenerate and re-export calendars at any point during the project. As forecasts update or your schedule changes, keep your MS Project calendars aligned with current data.
