Boston woke up Friday, April 3, 2026, to a gray start, with light drizzle and patchy fog trimming visibility across low-lying neighborhoods and along the waterfront. Temperatures sit in the upper 30s to low 40s this morning but should rise quickly inland, with a high near 62°F and south winds of 6–14 mph. A few spotty showers are possible before mid-morning, and inland areas are expected to see the best breaks of sun by midday while the coast stays cooler and socked in under the clouds.
Patchy fog will be the main headache for drivers and MBTA riders through the morning commute, especially on exposed bridges and around Logan. New rainfall amounts look light, generally under a tenth of an inch, and Small Craft Advisories will be needed for many coastal waters later today, according to the National Weather Service. Keep the headlights on in the fog and give yourself extra time if your route takes you near the harbor.
Afternoon Winds Pick Up
Southwest winds will strengthen through the afternoon and could gust into the 20–25 mph range inland, with even higher coastal gusts where the low clouds manage to break. Boaters should plan on choppy seas and periods of reduced visibility once advisories begin, and less-experienced mariners are urged to stick to sheltered waters or stay ashore.
Weekend Outlook
Saturday starts off on the mild side inland, with highs near the upper 50s, but a backdoor cold front will shove cooler ocean air back toward the coast and trigger a sharp seaside temperature drop in the afternoon. Showers become more likely Saturday night into Sunday, and Sunday looks windier with widespread rain and gusts that could reach near-gale levels over open waters, so plan accordingly and keep an eye on changing conditions.
