Understanding a seven-day forecast
Use the week to organise alternatives
The weekly view helps compare dates, but each card is a compact selection of model data. Start with the days relevant to your plans, then return to the hourly view as the date approaches. An outdoor plan can have an indoor alternative without assuming that a single icon settles the whole day.
What the temperature range includes
Clima Europa groups forecast points by the destination’s local calendar date and displays the lowest and highest available temperatures. These are not measured daily extremes or a continuous record.
For today, points that have already expired are excluded. This means the range can change as the day advances even when the provider has not issued a new model. Later days may have wider gaps between forecast points, which can miss a temperature peak between them.
Why the icon is not a daily verdict
We choose an available forecast point close to local midday for the card’s icon and precipitation interval. Read the interval and the “from” time under the card. A dry interval near midday does not establish that the morning or evening will also be dry.
We do not add overlapping precipitation intervals to produce an invented daily total. For plans at a particular time, use the available hourly points and consult the guide to reading a forecast.
What a refresh actually changes
Refreshing the page does not force the weather provider to publish a new forecast. Our server reuses responses until the provider permits another request. The active browser page checks its forecast cache once a minute and keeps a response for no longer than 30 minutes. The server still respects the cache expiry set by the provider, so a new browser request can return the same model.
A refresh therefore may show the same model update time. This is expected when the latest permitted response is unchanged. The site does not promise new model output or new half-hour forecast points every 30 minutes.

Worked example: today’s range changes without a new model
Imagine three available points: 12 °C at 09:00, 18 °C at 12:00 and 16 °C at 15:00. Their range is 12–18 °C. Once the 09:00 point is no longer included in the displayed hours, the remaining range is 16–18 °C.
This does not mean the day’s observed minimum has risen. The set of forecast hours being summarised has changed. An afternoon card therefore cannot reconstruct the morning’s weather. These values are illustrative; actual values depend on the model response.
Comparing two dates fairly
Check whether both dates contain points relevant to your plans. A later date with fewer points does not provide the same time detail as today. A one-degree difference alone is not a reliable reason to choose one day for an activity.
For a fixed-time plan, revisit the hourly view when the relevant points become available. We do not publish a “best day” score: that would require your schedule, activity and more information than a compact card provides.
