Preview picture, not a photo of crochet. Your blanket will differ: your colors, your city and your weather decide the stripes. Here every stripe has the same width and the shape is wider than a Narrow Throw; in your blanket each stripe follows your weather.
This crochet temperature blanket turns a year of weather into stripes: one row of single crochet a day, in the color that matches the day's high temperature in °F. It is plain back-and-forth rows, so you can watch TV while you hook.
You get a free pattern for 2 sizes (Narrow Throw, 36 x 74 in, and Throw, 50 x 74 in), a 10-color chart, yarn estimates and a printable tracker. Start on January 1, 2027, or catch up later.
What Is a Crochet Temperature Blanket?
A temperature blanket is a blanket made one row a day. Each day you check the high temperature, pick the matching color from your chart, and crochet one row. After 365 rows you have a year of weather in stripes. This one is plain single crochet, so every row looks the same except for its color.
How Many Rows Is a Temperature Blanket?
Time
About 74 hours (Narrow Throw) or 102 hours (Throw), estimated, not timed
Finished size
Narrow Throw about 36 x 74 in, Throw about 50 x 74 in (approximate)
Yarn
DK weight (#3), 10 colors + 1 border color: about 2680 yd (Narrow Throw) or 3720 yd (Throw) in all
Hook
US G-6 (4 mm)
Gauge
Suggested only, not swatched: 18 sts and 20 rows = 4 in (10 cm) in single crochet with DK (#3) yarn and a US G-6 (4 mm) hook. Measure your swatch and adjust.
Stitches
Chain and single crochet only; 365 rows, so a long project
Length
The length comes from the 365 rows: we assume 20 rows = 4 in, so about 74 in. If your swatch has 22 rows in 4 in, your blanket will be about 67 in long. The rows stay 365 (one per day); only your yarn weight and tension change the length.
Rows
365 rows, one per day. 2027 is not a leap year, so the count is exact.
How this pattern was checked
Every row of both sizes and both borders was replayed and counted by software: 734 of 734
Two independent readings of the rows agree
Not crocheted yet: sizes, yarn and hours are estimates. Make the swatch first.
All numbers are estimates, with a 15 % margin. Narrow Throw: about 2,680 yd in all, about 7.2 yd per row. Throw: about 3,720 yd in all, about 10.0 yd per row. Yarn is DK weight (#3). Your weather decides how it splits by color. Plan 220 yd (Narrow Throw) / 310 yd (Throw) per 30 days of one color.
Multiply the yards per row by the number of days you expect in each range, and add a skein for the ranges your city sees most.
With 250-yd skeins: about 34 rows per skein (Narrow Throw) or 24 (Throw). The 10 colors above add up to the whole year, whatever your weather: the total is about 2680 yd (Narrow Throw) or 3720 yd (Throw).
Yarn needle, scissors, stitch markers.
Use one brand and one dye-lot family if you can: a year of rows is long and a thinner yarn changes the length.

Narrow Throw is about 36 x 74 in: foundation chain 161, 160 sc per row, about 74 hours (estimate). Throw is about 50 x 74 in: foundation chain 224, 223 sc per row, about 102 hours (estimate). The length comes from the 365 rows: we assume 20 rows = 4 in, so about 74 in. If your swatch has 22 rows in 4 in, your blanket will be about 67 in long.
Narrow Throw (about 36 x 74 in) and Throw (about 50 x 74 in) share the same length. Row 1 is at the bottom; the border is the band between the 2 outlines; the cream border is drawn wider than real, for clarity. A computer drawing. Tap to enlarge: Open it full size
Our gauge is an estimate, not a measurement. Ch 21 and work 24 rows of sc (20 sts, about 4.5 in wide). Measure 4 in: we assumed 18 sts and 20 rows. Fewer sts, go down a hook size; more sts, go up. If your rows are shorter, your blanket will be shorter than our table.
High, Low or Average: Which Temperature Do You Use?
This pattern uses the day's HIGH temperature in degrees F. Pick one weather source for your city and stay with it all year. The rule is simple: look up the high, find its range in the chart, and crochet ONE row in that color. Row 1 is January 1 and Row 365 is December 31. If you start on another date, number your rows from your own first day; the pattern is the same.
Turning ch (ch 1): it does not count as a st. Work the first sc in the very first sc and the last sc in the last sc of the row, never in the turning ch.
Changing color: work the last sc of the row until 2 loops are on the hook, drop the old color, and pull the new color through both loops. Ch 1 and turn as usual. If the next row has the same color, keep going with the same yarn. Leave a 4 in tail at every change and weave it in on the wrong side.

Gauge (suggested, not swatched): 18 sts and 20 rows = 4 in (10 cm) in single crochet, DK (#3) yarn, US G-6 (4 mm) hook. The foundation, the rows and the color change are in the cards below.

Is It Too Late to Start? A Catch-Up Plan
No. Look up the row number for today's date in the table above. Your goal is to be on that row. Rows behind = today's row number minus the rows you have done. Look up past highs for each missed date, then crochet those rows in order, a few each evening. If you miss a day, write down the temperature the next morning and crochet two rows. You can also start on your own first day and number the rows from there.
Tips to Keep Going All Year
Keep the foundation chain loose. Place a stitch marker every 25 ch and count again. Put a marker in the first sc of every row. If the sides ripple, you have too many sc at the ends; if they pull in, work 2 sc in the first or last st now and then and count again.
This pattern has 365 rows, one for each day of the year (in a leap year, February 28 and 29 share one row).
How much yarn do you need for a crochet temperature blanket?
About 2,680 yd of DK weight (#3) yarn in all for the Narrow Throw and about 3,720 yd for the Throw, estimated with a 15 % margin. The split by color depends on your weather.
Do you use the high, low or average temperature?
This pattern uses the day's high temperature in degrees F. Pick one weather source and keep it all year.
Is it too late to start a temperature blanket?
No. Find today's row in the date table, look up the past highs, and crochet the missing rows a few at a time. Or number your rows from your own first day.
How big is a crochet temperature blanket?
Narrow Throw is about 36 x 74 in and Throw is about 50 x 74 in. The length comes from the 365 rows; if your swatch has 22 rows in 4 in, it will be about 67 in long.
