Humidity comfort
Share of days at each humidity comfort level, based on the dew point — the measure that tracks how muggy it actually feels.
Humidity comfort is graded by the dew point — the temperature at which the air would be fully saturated — because it tracks how muggy it actually feels far better than relative humidity does. A low dew point feels dry and crisp; a high one feels sticky and oppressive no matter the reading on a humidity gauge.
In Waal, how humid it feels changes dramatically over the year.
The more humid part of the year lasts 3.1 months, from around March 19 to June 19. The muggiest month is May, when the air feels humid, muggy or worse about 93% of the time.
The most comfortable stretch runs from around November 29 to March 18, and February is the most comfortable month — the air is dry or comfortable 88% of the time.

Wind
Average wind speed through the year, banded into plain-language speed zones so a number reads as 'breezy' or 'calm' without knowing the scale.
This is the average sustained wind speed at the standard 10 metres above open ground — the steady flow a weather station reports, not the sharper gusts that come and go, which can run half again as fast. It's the number that says whether a place is generally breezy or calm.
Across the year, average wind speed in Waal is typically light breeze, near 16 km/h, and varies a lot with the seasons.
The windier part of the year lasts 4.1 months, from around May 23 to Sep 25. The windiest month is July, averaging about 26 km/h (breezy).

Average hourly UV index in Waal
Modeled clear-sky UV for every hour of every day — when in the day sun protection actually matters.
The whole year hour by hour: each column is a day, each row an hour, and the color is the modeled clear-sky UV index — the midday peak scaled down as the sun sits lower in the sky. Darker overlays mark night, lighter ones the civil-twilight hours around sunrise and sunset.
UV falls off far faster than brightness as the sun drops, so even in March the burn window is concentrated in the middle of the day: about 8 hours a day reach index 3 (protection recommended), and 6.5 hours reach 6 or more. Mornings and late afternoons stay comparatively gentle year round.

Growing degree days
Growing degree days tally heat above 10°C: each day adds however many degrees its average temperature runs over that threshold, and cold days add nothing. Waal banks about 6,384 degree days a year, and the running total — which growers use to time plantings and predict maturity — climbs fastest around September.

Solar energy
Average daily shortwave solar energy reaching the ground, banded into brightness zones so the number means something at a glance.
Solar energy is how much sunlight actually reaches the ground each day, measured in kilowatt-hours per square metre (kWh/m²) — the combined effect of how long the sun is up, how high it climbs, and how much cloud gets in the way. It's the raw fuel a solar panel has to work with: for scale, 1 kWh/m² a day is dim and wintry, while 7+ is desert-bright.
Waal receives about 5.9 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 4.7 and 7.2 kWh/m².
The brighter stretch of the year lasts 4.8 months, from around Nov 28 to Apr 23. The brightest month is March, averaging about 7.1 kWh/m² (intense).
The dimmest month is June, down near 4.9 kWh/m² — roughly 31% less than the March peak.
