34 | OHCC LIVING | DECEMBER 2025 | In Search of Wind Wind over San Diego Bay is like a box of chocolates: "You never know what you're gonna get!" On a recent Thursday, First Mate Stephanie Hewitt clocked a brisk 6.6 knots — a season record. The very next day, our sailors met f lat seas, calm winds, and a blanket of fog. Planning starts early — often a day or more in advance. We consult our go-to sailing apps — Windy, iNavX, and Argo — and study forecasts, tide charts, and swell predictions. Even on the drive down, captains quietly read the coastline: the shimmer of fog, the bend of trees, the movement of clouds. Once we arrive, the real detective work begins. Are the palm trees swaying or standing still? Are f lags snapping sharply or hanging limp? Even the water tells a story — its color, the ripples, the way they move across the surface. These clues help us decide when to hoist the sails and set the best plan for the day. Once underway — where the real fun begins — performance depends on finding good wind, predicting changes, and adapting both boat and crew. Understanding apparent wind — the wind your sails actually "feel" — is key. It's a combination of true wind and the wind created by your boat's motion. As speed increases, apparent wind shifts forward and strengthens—making precise sail trim essential. Upwind, you'll want f latter sails to reduce drag; downwind, fuller sails capture more power. Adjusting sheets, using the traveler, and fine-tuning the outhaul and halyards all play a role in shaping the sail for efficiency — and gaining that extra knot or two of speed. San Diego Bay, a semi-enclosed natural harbor, is particularly fraught with fickle winds. Heading out toward Buoy #1 and the open sea, captains often feel tension. Wind shadows cast by the 400-foot-high Point Loma Peninsula can stir unease. One moment, the wind trickles down the slope; the next, it gusts with force. Doubt creeps in: Will the sails fill? Will the gusts be handled smoothly? San Diego Bay's unique geography creates its own microclimate. Winds here benefit from the "sea breeze phenomenon," in which inland areas heat up faster than the ocean throughout the day. As warm air rises over land, cooler, denser air from the Pacific is drawn in, creating a consistent onshore f low. This breeze typically builds from late morning, peaks in the afternoon (8–12 knots), and fades by evening — the "good winds" everyone loves. Each captain has a recipe for conquering whatever wind appears. And behind the scenes — great conversation, shared snacks, and the artful ballet of crew adjusting sails — round out each sailing day. As our 2025 sailing season came to an end, we celebrated 120 sails with a membership of 291. A huge thank you to all who make these sails happen, especially our talented captains and behind- the-scenes managers. Written by Pat Melzer in collaboration with ChatGPT Sailing Club
