Seasonal background

Spring background

In temperate regions, spring brings longer days and a gradual transition out of winter. Coasts, inland areas and higher ground can change at different speeds. A mild afternoon does not rule out overnight frost, and snow may remain at altitude after low ground has cleared.

Plan with the right time horizon

For plans far ahead, compare seasonal conditions and daylight. Check a local weather forecast closer to departure, then review its hourly detail and official warnings. Monthly averages cannot tell you whether a particular day will be dry, calm or snowy.

A changing climate

As the climate changes, familiar patterns of temperature, rainfall and snow can shift. Historical averages provide a reference, not a guarantee for future years. Climate projections describe possible longer-term changes under stated assumptions; they do not predict the weather on your selected day.

What the numbers mean

Weather values use available forecast data for the selected date. Climate values are historical monthly means for the stated reference period and location. Daylight comes from astronomical calculations. These describe different things and are labelled separately; missing data are not replaced with invented daily forecasts.
