Monthly Planning Average reports

Planning average reports provide you with the average expected weather conditions for a given month. Looking over a 30 year period we can provide a clear picture of what seasonal norms you can expect at your site during your project.

The 1-in-10 year values and Long Term Averages provide a tool to help you identify potential downtime during a contract period enabling you to develop contingency plans and negotiate realistic contracts.

Our planning average reports are suitable for guiding NEC and JCT contracts.
When you are negotiating realistic contracts we produce analysis suitable for NEC and JCT contracts, including NEC clause 60.1 (13).  'With solid statistical evidence derived from Met Office observations both parties can agree on whether a particular month contains a compensation event' (NEC). Learn more about NEC3 & NEC4.
