Distribution across the twelve months
Why these months?
Bergen's canonical best-time window is May — 1 month of the year. That window is derived from the R1–R7 classification of NASA POWER climate normals, and it is the primary signal behind the verdicts above.
Inside the window, NASA POWER climate normals for a temperate climate in the northern hemisphere read Cool with Moderate precipitation — 1991–2020 monthly averages, not a forecast. Outside it, month-by- month verdicts come from the R1–R7 climate classification over the same dataset.
The other 11 months sit outside the window. Jan, Feb, Mar, Sep, Oct, Nov, Dec read as least favourable for this zone.

● marks a month inside the canonical best-time window
- Best
- Favourable month (R1–R7) inside the canonical best-time window
- Good
- Workable month (R1–R7) — a viable alternative outside the stated window
- Mixed
- Transitional month — workable with a flexible plan
- Avoid
- Challenging month (R1–R7) — least favourable climate pattern
Method: temperature and precipitation are 1991–2020 climate normals (monthly means); verdicts combine the R1–R7 climate classification with the canonical best-time window. No daily forecast, crowd level or price index is claimed.
