Santa Cruz weather by month, at a glance
The whole year in one picture — sky, rain, humidity, temperature and travel score. Click any band to jump to its full chart.
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 April to early 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 Santa Cruz, how humid it feels changes dramatically over the year.
The more humid part of the year lasts 6.7 months, from around October 8 to April 29. The muggiest month is January, when the air feels humid, muggy or worse about 100% of the time.
The most comfortable stretch runs from around April 30 to October 7, and July is the most comfortable month — the air is dry or comfortable 50% 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 Santa Cruz is typically light breeze, near 14 km/h, and varies little with the seasons.
The windier part of the year lasts 5.8 months, from around May 22 to Nov 13. The windiest month is August, averaging about 15 km/h (light breeze).
The calmer part of the year runs from around Nov 14 to May 21, with March the calmest month at about 12 km/h.

Best time to visit Santa Cruz
To characterize how pleasant the weather is in Santa Cruz throughout the year, we compute two travel scores — one for general sightseeing, one for beach and pool weather.
Around early May, Santa Cruz is still near the start of its best-weather window — great conditions with the peak-season crowds not yet at full swing.
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 Santa Cruz for general outdoor tourist activities is from late April to early September, with a peak score in the last week of July.

Average hourly UV index in Santa Cruz
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 January the burn window is concentrated in the middle of the day: about 8.5 hours a day reach index 3 (protection recommended), and 7 hours reach 6 or more. Mornings and late afternoons stay comparatively gentle year round.

Growing season
Santa Cruz is frost-free year round — even the coldest nights rarely reach freezing, so there is no start or end to the growing season.

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. Santa Cruz banks about 5,162 degree days a year, and the running total — which growers use to time plantings and predict maturity — climbs fastest around January.

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.
Santa Cruz receives about 4.8 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 3.1 and 5.9 kWh/m².
The brighter stretch of the year lasts 7.2 months, from around Aug 25 to Mar 30. The brightest month is January, averaging about 5.8 kWh/m² (bright).
The dimmest month is May, down near 3.4 kWh/m² — roughly 40% less than the January peak.
