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 La Flèche, how humid it feels changes noticeably over the year.
The more humid part of the year lasts 3.6 months, from around May 30 to September 16. The muggiest month is August, when the air feels humid, muggy or worse about 22% of the time.
The most comfortable stretch runs from around September 17 to May 29, and April is the most comfortable month — the air is dry or comfortable 100% 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 La Flèche is typically light breeze, near 13 km/h, and varies little with the seasons.
The windier part of the year lasts 5.9 months, from around Oct 18 to Apr 14. The windiest month is January, averaging about 14 km/h (light breeze).
The calmer part of the year runs from around Apr 15 to Oct 17, with August the calmest month at about 11 km/h.

Best time to visit La Flèche
To characterize how pleasant the weather is in La Flèche throughout the year, we compute two travel scores — one for general sightseeing, one for beach and pool weather.
Around late September, La Flèche is still near the tail of its best-weather window — great conditions with the peak-season crowds already thinning.
Inferred from the travel-score curve; month-by-month visitor numbers are a planned addition.
The travel score favors clear, rainless days with daytime highs between 18°C and 28°C. Based on this score, the best time of year to visit La Flèche for general outdoor tourist activities is from mid May to early October, with a peak score in the last week of August.

UV index (midday) in La Flèche by month
Clear-sky midday UV index through the year, shaded by the WHO exposure levels — how much sun protection each month calls for.
Under clear skies, the midday UV index in La Flèche peaks around August 10 at about 7 (very high) — sunscreen and a hat are worth it in the middle of the day. It bottoms out near January 1 at about 1 (low).
The index reaches 3 or more — the level where the WHO recommends sun protection — in 7 months of the year.

Average hourly UV index in La Flèche
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 August the burn window is concentrated in the middle of the day: about 7 hours a day reach index 3 (protection recommended), and 3 hours reach 6 or more. Mornings and late afternoons stay comparatively gentle year round.

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.
La Flèche receives about 3.4 kWh/m² a day of solar energy on average — moderate — with a clear seasonal swing between 0.9 and 5.8 kWh/m².
The brighter stretch of the year lasts 6.1 months, from around Mar 21 to Sep 21. The brightest month is June, averaging about 5.7 kWh/m² (bright).
The dimmest month is December, down near 0.9 kWh/m² — roughly 84% less than the June peak.
