Today is the longest day of the year, marking the official start of the summer solstice. The sun is positioned at its farthest northern point, directly overhead at noon. Elsewhere, the warmest part of the day is after noon when the sun is highest in the sky. As noted in a previous column, the heat kicks in due to the lag-time required for the ground and water to heat up. North of the Arctic Circle, there’s continuous sunshine for 24 hours. Sunset in Barrow, Alaska, won’t occur until Aug. 2. Along the U.S.-Canadian border, the sun appears for 16.25 hours and 13.75 hours in Baton Rouge. Fastcast: Summerlike.
