Weather isn't just an inconvenience - it's a safety obligation

When wind gusts exceed structural limits or lightning approaches your site, you need more than a forecast - you need documented, defensible data. eventPassport brings together multi-provider forecasts, on-site sensor data, and real-time lightning tracking into a single auditable platform.

Whether you're managing a wind action plan for temporary structures or demonstrating due diligence after a weather-related closure, every data point is timestamped, archived, and exportable.

Yellow Warning Amber Warning Red Warning

Met Office severe weather warnings displayed automatically when they affect your event location.

Why event professionals trust our weather data

Built specifically for the operational and compliance demands of outdoor events

Multi-provider aggregation

Don't rely on a single forecast source. Compare predictions from multiple weather providers to understand the full range of potential conditions. Select which models to include in your highs analysis and make informed decisions based on the forecasts you trust most.

On-site sensor integration

Forecasts tell you what might happen; sensors tell you what's actually happening. Connect ultrasonic sensors for real-time ground truth, updated every minute. Weather varies dramatically over short distances - know your venue's exact conditions, not a regional forecast that might miss what matters.

Live lightning tracking

Real-time lightning strike visualization with colour-coded time markers - see at a glance which strikes are recent (red) versus historical (grey). Distance circles around your venue mean no calculations required - just look at the map and know immediately if lightning is a threat.

Historical forecast archive

Every forecast downloaded is permanently archived. Go back to any date and time to review what was predicted versus what actually occurred - critical for insurance claims and incident investigations.

Automated morning briefings

Daily weather forecast PDFs automatically emailed to any address - not just system users. Keep your production team, safety officers, and contractors informed without manual effort.

Configurable alerts

Pre-configured alert emails notify key personnel when conditions exceed your thresholds. Wind approaching limits? Lightning within range? Your team knows before they need to ask.

Hour-by-hour precision

Plan your day with granular hourly forecasts showing temperature, feels-like, wind speed and gusts, humidity, pressure, cloud cover, air quality and precipitation probability. Know exactly when conditions will change.

  • Hourly breakdowns for 48 hours ahead
  • View data in your preferred units - °C / °F, mph / kph / m/s
  • Rain/snow probability with expected accumulation
  • UV index and air quality tracking
  • Dawn, sunrise, golden hour, sunset, and dusk times
Ground truth

Live sensor monitoring

Forecasts are predictions. Sensors are facts. Our integration with TempestOne and WeatherFile ultrasonic weather stations gives you real-time wind speed data plotted alongside forecast predictions - updated every minute.

  • Ultrasonic sensors - no moving parts, high reliability
  • Real-time wind speed graphed over time
  • Compare forecast vs actual conditions
  • Multiple sensor locations across your site
  • Automatic data logging for post-event analysis
Supported sensors: TempestOne WeatherFile

Industry wind thresholds

Reference guidance for temporary structure wind management policies

HSE guidance and the Institution of Structural Engineers recommend that temporary structures operate under "wind managed" policies with documented action thresholds. These typical industry values help you configure your own site-specific alert levels.

Wind Speed Typical Action
25 mph (11 m/s) Secure loose items, close tent sidewalls, first awareness
37 mph (17 m/s) Pause stage performances, heightened monitoring
45 mph (20 m/s) Consider evacuation of temporary structures
50+ mph (22+ m/s) Clear areas under all temporary structures

Actual thresholds depend on your specific structures and engineering specifications. Always consult your structural engineer and supplier documentation.

Safety critical

Live strike tracking for safety decisions

With 30-60 people struck by lightning annually in the UK - 72% during outdoor leisure activities - real-time strike tracking isn't optional. Our lightning map shows exactly where and when strikes occur near your event.

Within 1 min 2 mins 5 mins 10 mins 15+ mins

Make informed decisions about continuing activities or managing crowd safety. Distance circles and time-coded strikes remove guesswork - you can see exactly where lightning is occurring and how close it's getting. Timestamped records document the conditions that shaped your response.

Compliance

Your evidence trail for insurance claims

When an event closes due to weather, you face questions from insurers, stakeholders, and potentially regulators. Parametric weather insurance requires verified third-party data. Our archived forecasts and sensor logs provide exactly that.

  • Timestamped forecast archives - review any past date
  • Sensor data logs with minute-by-minute readings
  • Automated daily weather briefing PDFs as documentation
  • Evidence that decisions were based on real data
  • Demonstrable due diligence for safety decisions

Insurance claims require weather data from a national weather station or approved independent observer. On-site sensors with proper logging provide exactly this.
