Each stripe is one measure across the whole year, stacked so a single day reads top to bottom. The sky band runs overcast grey on top down to clear blue at the base — more blue means sunnier — followed by the rainfall curve, the humidity band, a temperature strip that tints each stretch of the year by how warm its average high is, and the travel-score line at the foot. Scan straight down any date to read that day across every measure at once; the score climbs highest around late June to mid September.

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 Kenmore, the air stays dry or comfortable essentially all year. Even in August, the muggiest month, it feels humid or worse only about 2% of the time — humidity is not something you need to plan around here.

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 Kenmore is typically calm, near 6 mph, and varies moderately with the seasons.
The windier part of the year lasts 6.0 months, from around Oct 14 to Apr 14. The windiest month is December, averaging about 8 mph (light breeze).
The calmer part of the year runs from around Apr 15 to Oct 13, with August the calmest month at about 4 mph.

Best time to visit Kenmore
To characterize how pleasant the weather is in Kenmore throughout the year, we compute two travel scores — one for general sightseeing, one for beach and pool weather.
Around early September, Kenmore 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 64°F and 82°F. Based on this score, the best time of year to visit Kenmore for general outdoor tourist activities is from late June to mid September, with a peak score in the first week of August.

UV index (midday) in Kenmore by month
Clear-sky midday UV index through the year, shaded by the WHO exposure levels — how much sun protection each month calls for.

Average hourly UV index in Kenmore
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 July the burn window is concentrated in the middle of the day: about 8.5 hours a day reach index 3 (protection recommended), and 4.5 hours reach 6 or more. Mornings and late afternoons stay comparatively gentle year round.

Growing season
Kenmore is mild enough that a frost-free day stays more likely than not even in midwinter. Nights are reliably above freezing from about January 16 to December 5 (324 days); outside that window a hard frost is an occasional risk.

Growing degree days
Growing degree days tally heat above 50°F: each day adds however many degrees its average temperature runs over that threshold, and cold days add nothing. Kenmore banks about 1,657 degree days a year, and the running total — which growers use to time plantings and predict maturity — climbs fastest around August.

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.
Kenmore receives about 3.4 kWh/m² a day of solar energy on average — moderate — with a clear seasonal swing between 0.8 and 6.1 kWh/m².
The brighter stretch of the year lasts 6.0 months, from around Mar 26 to Sep 25. The brightest month is July, averaging about 6.0 kWh/m² (intense).
The dimmest month is December, down near 0.9 kWh/m² — roughly 86% less than the July peak.
