An educational library of workplace documents — purpose, who completes them, when they are used, typical fields, common mistakes and how they connect. Linked to workplace safety, workplace training, occupations, industries and employment documents. Informational only — template examples, not legal advice or official documents; employers remain responsible and using a document does not guarantee compliance.
What an adverse weather risk assessment is
An adverse weather risk assessment examines how conditions such as high wind, heavy rain, ice, snow, extreme heat or cold, and lightning affect work — particularly at height, with lifting, in vehicles or outdoors — and records the limits, monitoring and controls that keep work safe or trigger it to stop.
This page is an educational overview with a simplified example. It is not an official template, not jurisdiction-specific and not legal advice — the employer decides what their adverse weather assessment must cover.
Purpose
- Identify how weather affects the planned work.
- Set thresholds at which tasks must be modified or stopped.
- Record monitoring of forecasts and on-site conditions.
- Address heat, cold, slips, visibility and wind effects.
Who completes it
- A competent person appointed by the employer.
- With input from those who do the exposed work.
- Reviewed within the organisation’s own process.
- It is the employer’s responsibility to ensure the assessor is competent.
When it is used
- For outdoor, exposed or weather-sensitive work.
- When seasons or forecast conditions change.
- Before tasks affected by wind, ice or heat.
- After a weather-related incident or near miss.
Typical fields
- Task and how weather affects it.
- Conditions of concern — wind, rain, ice, heat, cold, lightning.
- Thresholds to modify or stop work.
- Monitoring, clothing, shelter and rest arrangements.
- Communication and review date.
- Example fields only — adapt to the work and the applicable law.
Common mistakes
- Continuing high-risk work in unsafe wind or ice.
- No clear thresholds for stopping work.
- Ignoring heat or cold stress on workers.
- Not monitoring forecasts and changing conditions.
Document workflow
An adverse weather risk assessment sits alongside task assessments such as working at height, lifting and workplace transport, and feeds the safe system of work and dynamic risk assessment on the day. A forecast change or incident triggers a review or a stop.

Retention (high level)
Adverse weather assessments are generally kept for as long as they are relevant and for a period afterwards, in line with the employer’s obligations. Specific retention periods vary by jurisdiction.
This page does not state a required period — confirm retention with the applicable law and the official authority.
Completing and sharing as a PDF
Adverse weather assessments are commonly completed and stored as PDFs alongside task assessments and method statements. Exporting to PDF supports documentation; it does not make the assessment official or guarantee compliance.
Employer checklist
- Set clear thresholds for modifying or stopping work.
- Monitor forecasts and on-site conditions.
- Provide for heat, cold, shelter and rest.
- Communicate changes and review after incidents.
Worker notes
- Stop affected work when conditions reach the agreed limits.
- Dress for the conditions and take breaks as planned.
- Report worsening weather and any unsafe situations.
Country considerations
Expectations around weather, heat, cold and outdoor work vary by country, and the official authority differs. This page is high-level and general — it is not a statement of any country’s law and not a guarantee that a document is valid anywhere.
Always confirm the current requirements with the official authority for your country and a qualified professional.
Who is responsible
The employer is responsible for assessing and managing the effects of weather on work and compliance. This page is an educational overview with a template example; it does not determine what your assessment must contain, does not make a workplace compliant and does not transfer responsibility.
