How are these trends calculated
Same period, year after year
For each future day, we look at the comparable dates observed over 18 years, with a rolling window of 15 days around the target day.
More weight to recent years
The most recent years are weighted slightly more to better reflect recent changes in weather conditions.
How to read the prevailing weather
The prevailing weather corresponds to the most frequent weather scenario over the displayed period. The percentage indicates its estimated share, and the other weather types shown in smaller size display the possible secondary scenarios, especially useful in weekly or monthly forecasts.
Months are calculated separately
Monthly trends are calculated directly from historical months to avoid artificial daily accumulations.
How to read confidence levels
The confidence score summarizes how much the model runs converge on a stable weather scenario for the displayed period.
high confidence
70 to 100
Past years tell a fairly coherent story: temperatures, rainfall and weather type vary little around the dominant scenario.
average confidence
45 to 69
A clear trend exists, but with greater year-to-year variations. The result should be read as a probable direction.
limited trust
0 to 44
The archives are more scattered over this period. The displayed scenario remains useful as a reference, but it should be interpreted with caution.
In practice, confidence is generally more robust over months than over weeks, because longer periods smooth out weather variability more.
Limits to keep in mind
- This is a long-term trend based on historical data, not an operational weather forecast for a few days.
- Exceptional or very localized episodes may deviate significantly from the most likely scenario.
- Monthly trends are generally more reliable for choosing a period, while day-by-day detail is mainly used to refine pinpointing.
