Heat risk is not only outdoors
In the UK, indoor overheating can be a key risk, especially in flats and rooms with strong afternoon sun. Track room temperature, manage shading, and plan cool spaces.
Interpreting trends and extremes
Insights for 2025: what to watch and how to read it
This page offers practical explainers that help you interpret climate information in a UK context. Instead of focusing on single-day headlines, we focus on patterns that affect planning: heat risk and indoor comfort, heavy rainfall intensity and surface-water flooding, and seasonal shifts that can influence energy demand, travel disruption, and health protection. Use the cards below to open a short explainer, then visit the Actions page for checklists you can implement.

We explain baseline periods, anomalies, and what “record” often means in practice.

Three useful lenses
To interpret UK climate information in 2025, three lenses often help. First, separate averages from extremes. A small shift in the average can still increase the likelihood of very hot days or intense downpours. Second, consider exposure and vulnerability: the same meteorological event affects people differently depending on housing quality, access to transport, health conditions, and workplace settings. Third, look for persistence. A single storm is weather, but a repeated pattern of intense rainfall seasons can point to a changing risk profile for surface-water flooding and damp.
Surface-water flooding can be fast
Intense rainfall can exceed drainage capacity, even away from rivers. Routine checks like clearing gullies and knowing safe routes can reduce disruption.
Comfort, energy, and health overlap
Ventilation and insulation choices influence both summer comfort and winter damp. Aim for balanced measures that keep air quality high and moisture controlled.
How to read a “record” responsibly
Records can be meaningful, but they can also be misunderstood. A record might be for one station, one day, a limited subset of years, or a specific definition of “UK-wide average.” In practice, a better question is whether extremes are becoming more frequent, whether seasons are shifting, and whether the impacts are changing because of exposure. That is why this site emphasises planning-relevant indicators such as duration of warm nights, persistence of wet spells, and the timing of high-demand periods for energy and transport.
If you are briefing a team, consider summarising information with three lines: what changed, who it affects, and what you will do next. You can use the Actions page to convert insight into a small plan, then refine it over time.
Mini checklist
- Check the time period and baseline used for comparison.
- Confirm the geography: one station, a region, or a UK-wide average.
- Translate the number into a decision: what changes in operations, maintenance, or messaging?
