Portsmouth, New Hampshire — 2027 Tide Poster (Currents)

Every high and low tide in Portsmouth Harbor for all of 2027, on one wall.

Each of the 365 small dials is a day. Its hands point to the hour of high water the way a clock would, and the exact times are printed beside it: bold for highs, light for lows. The twelve highest tides of the year are marked in gold. Beneath the dials, the water itself is drawn as the current of the calendar: the tide arrives about fifty minutes later each day, so the hands turn as the year runs down the page.

Tide predictions are from NOAA's Portsmouth Harbor station. Highest tide of the year 10.0 ft, mean range 7.7 ft. Moon phases are shown in the margin. For planning the year, not for navigation.

Printed to order in the USA on heavyweight 189 gsm matte paper with archival pigment inks. Ships rolled in a rigid tube, or framed in black wood and ready to hang. Gift note included on request at checkout.

Sizes: 12 x 18, 18 x 24, 24 x 36 inches. Also available in the Strokes design.
