Ten-year averages — the general picture of the place. How individual years differ (and they do) is what the dated report shows.

Precipitation: dots rate the month from dry (one) to very rainy (four); the number is the water of a typical year (median of ten), rain plus melted snow — a couple of freak seasons can't distort it. A rainy day means real, lasting rain — 3+ mm falling through 10+ hours of the day (breaks between showers count); a short summer shower doesn't make a day rainy. High summer totals usually come from short thunderstorms, not long rain. A sunny day keeps the sky more than half clear (average cloud cover below 50%), a grey day is fully overcast (90%+); the rest sits in between. Wind is the typical daily top wind speed, m/s. Temperatures and day counts are 10-year averages.
April 1–5, two real years
The table above says April: 9.9°…20.1°. True — and useless for your five days. Same dates, two years:
Dry all five days.
62 mm of rain.

Your exact dates, all ten years
The passport tells you what this place is like. The dated report answers the real question — what will YOUR days most likely look like:
Eight slices of every day with typical and extreme temperatures — morning flight, beach noon, dinner terrace.
Rain, heat, cold nights, gusts — each as “N years out of 10” with countable dots.
All ten years side by side, best and roughest flagged. The spread averages hide.
A week earlier and later, compared — sometimes seven days change the whole trip.
Thunderstorms, hail, squalls on your dates across ten years — with the year attached.
“Days around 17°, pack an umbrella, chilly after sunset.” From the numbers.
