How Should Weather Affect a Site Inspection Record?
Record weather when it affects what you can observe or safely access. Weather is context, not a diagnosis. A dry visit cannot show how every part of a building behaves in rain, and a photograph taken during rain does not establish the source of a leak.

Decide whether the planned work can proceed
Check site conditions and the responsible person's arrangements before starting exposed work. If conditions make access unsuitable, change or postpone the affected part of the visit. Follow the site's safety procedures and do not create an access risk to complete a photograph or preserve an appointment time.
Identify the actual limitation. “External north elevation not reviewed because access was unavailable under the site arrangements” is more useful than a general “bad weather” note. Some internal work may still proceed while a named external task is deferred. Agree that division and keep the remaining work visible in the visit record.
Record observed conditions precisely
Describe the conditions you directly experienced and, where relevant, their timing: rain during the external walk, glare on a surface, wet finishes or reduced visibility. Distinguish that from weather reported by someone else before your arrival. Do not label a stain “storm damage” solely because a storm occurred recently.
An example is: “Rain was falling during the visit. A wet mark was visible on the internal sill at 10:20. The source was not established during the visual inspection.” This records something useful for further assessment without pretending to identify the route water took through the construction.
Keep comparisons fair
If a later visit occurs in different conditions, state the difference. “No water observed during today's dry visit” is narrower and more defensible than “leak repaired.” The evidence needed to assess a repair should be agreed with the appropriate person and may require conditions or testing outside your visit's scope.
- Keep the original observation and its date.
- Add the later conditions and what was actually checked.
- Explain any differences in access, lighting or visibility.
- Record the next assessment step when the result remains uncertain.
Do not conduct improvised water tests or operate building systems outside your authority and competence to recreate the problem. Arrange a suitable investigation when needed.
Tell the recipient what the limitation means
Explain the practical consequence of the weather note. Does an area need a later visit? Does a reported intermittent problem require more information? Is a finish comparison deferred because the viewing conditions were unsuitable? Give the next action and the person responsible for arranging it, if agreed.
The water-stain recording guide helps separate visible evidence from suspected causes. Photographs should support that distinction: use captions that name the location and observed condition, with weather context only where it matters. Useful weather reporting helps the next person interpret the visit; it does not fill gaps in evidence with a confident-sounding explanation.
