Embroidery through Diamond Bar's year
With 11 months averaging a high of 70°F or more, polos stay in season, and a light stitch density keeps thin performance knits from puckering. About 11 nights a year reach freezing (32°F), enough for a few cuffed beanies with a short, wide logo on the cuff. On the roughly 23 days a year that reach 100°F, a performance polo wicks sweat and dries faster than heavy cotton piqué. At about 10 inches of rain a year, most days are dry, and caps stay in rotation all year.
Diamond Bar's weather figures come from the same NOAA stations as Corona's (Chino Airport), so the month-by-month table is on the Corona page.
