Explore broadly dry, less-cloudy spells. Check summit conditions in the detailed forecast.
Multi-day windows need support for the whole spell in the same sampled locations. Longer spells come first, then whole-spell support. Percentages describe alternative outcomes within one forecast model, not certainty.
Some dates or areas have incomplete data. Only assessed dates are shown; missing dates do not mean no weather window.
No continuous spell in the available assessments meets the combined weather-window checks. A promising morning or a single dry day is not enough to qualify the whole period. This is a guide to the strength and continuity of the signal, not a verdict on every day out.
There are shorter opportunities below. Check the detailed forecast for their timing and conditions.
Daily dry, less-cloudy signals, ranked by model support. Adjacent days are not automatically a continuous spell.
These have lower or unavailable model agreement. Unknown agreement is not a zero score.
A drier spell with less cloud is worth watching, but other outcomes or parts of the area are less favourable. Support varies across the sampled parts of the area. This broad outlook cannot confirm clear summits or manageable summit winds; check the detailed mountain forecast nearer the time.
High pressure and largely dry conditions are possible, but cloud may remain extensive.

Whole-spell support counts forecast outcomes with dry, less-cloudy conditions and a lower surface-wind signal in the same sampled places throughout the spell. It is not a hill-day score or a calibrated probability. The outlook does not assess summit gusts, thunder or cloud base. Check the detailed forecast before setting out.
