Staten Island Friday in one sentence
The borough wakes up at 50°F under mostly cloudy skies with a brief, low-odds shower window before 11 a.m., then clears to partly sunny with a high of 69°F — the warmest of any borough today — under a 14 mph northwest breeze, before settling into a mostly clear 54°F overnight. If you’re commuting off-island or running the ferry-to-Manhattan route, the weather is not your problem today. The Staten Island Railway, however, is.
The SIR boarding change every South Shore commuter needs to know
Between 9:45 a.m. and 3:00 p.m. today, the Staten Island Railway is running a scheduled-maintenance boarding change affecting four South Shore stations: Arthur Kill, Richmond Valley, Pleasant Plains, and Prince’s Bay. The MTA real-time service status feed (verified 5:32 a.m. ET) lists the change as “scheduled maintenance” — not weather-related. If you ride out of any of those four stations between 9:45 a.m. and 3:00 p.m., expect to board from the opposite platform or a temporary location at your station. The SIR’s 7:21 a.m. southbound and 8:36 a.m. northbound trains run on the normal schedule because the change starts at 9:45 a.m. The rush-hour window is unaffected; this is a midday issue for off-peak riders, retirees heading to St. George, and anyone making the morning return trip from Tottenville.

SIM express bus disruption (the part SI Live doesn’t usually catch in time)
Several SIM express bus routes have active alerts at publish time. The SIM1C and SIM3C — the Manhattan-bound expresses from the South Shore — are on a planned detour today because of the Asian Pacific American Cultural Parade in Midtown. The 6th Avenue/West 50th Street drop-off will be made on 3rd Avenue instead. If you ride either route to a meeting on 6th Avenue, walk one avenue east when you get off. Real-time bus tracking on BusTime may be inaccurate while buses are on the detour route.
Separately, the SIM11, SIM6, SIM22, and SIM26 have planned stop-skips this morning due to water main construction along their routes. The SIM5, SIM15, SIM26, and SIM35 have boarding-location changes for construction. None of these are weather impacts — Staten Island infrastructure work is the constant; the weather today is the cooperative variable.
Alternate side parking on Staten Island today
ASP is in effect on Friday, May 15, 2026, including on Staten Island. Yesterday (Thursday, May 14) was an ASP suspension day for the Solemnity of the Ascension; today is not. If you moved your car yesterday and parked on a no-parking-during-cleaning side, you need to move it again to your normal regulation today. The next suspension is Friday, May 22 (Shavuoth). Confirmed via the NYC DOT 2026 suspension calendar at nyc.gov/site/dot/motorists/alternate-side-parking.page.
DSNY on the Island
DSNY runs the regular Friday schedule today. No holiday delay, no weather-related route change. Standard set-out rules apply: containerized trash and organics out after 6 p.m. Thursday for Friday morning collection. The DSNY collection schedule lookup is at nyc.gov/site/dsny/services/collection-schedule.page.
Staten Island microclimate notes
The borough’s south- and east-facing exposure across Raritan Bay typically gives Staten Island a 1–3°F daytime advantage in spring west-to-northwest flow patterns. That’s playing out today: SI’s 69°F high is the warmest in the city, 4°F warmer than Manhattan’s 65°F. The northwest wind hits the North Shore (St. George, Stapleton, Tompkinsville) harder than the protected mid-island and South Shore neighborhoods. Expect mid-island spots like New Springville and Heartland Village to feel several degrees milder than the breezy ferry terminal. Coastal water temperatures in Lower New York Bay are still in the low 50s — pleasant to look at, not to swim in. Lifeguarded swim does not begin at South Beach, Midland Beach, Wolfe’s Pond, or Cedar Grove until Memorial Day weekend; check with NYC Parks for the exact opening date.
Specific resident decisions for Staten Islanders today
- If you ride the SIR from a South Shore station midday: Build 5 extra minutes into your trip between 9:45 a.m. and 3:00 p.m. Boarding location moves.
- If you take the SIM1C or SIM3C to Midtown: Get off one stop earlier than normal and walk east one avenue — you’ll be dropped on 3rd Ave, not 6th.
- If you drive to the ferry: ASP is on. Move your car or take the bus to the terminal.
- If you walk a kid to PS 19, PS 39, PS 5, or any North Shore school: Light layer plus rain jacket for the morning; afternoon walk is hoodie weather. Confirm school day status at schools.nyc.gov/about-us/news/school-year-calendar.
- If you golf at Silver Lake or LaTourette: Tee off after 11 a.m. for the best window. Wind out of the northwest at 14 mph will affect ball flight on west-facing fairways.
- If you bike the SI Greenway or the North Shore Esplanade: Tailwind heading southeast, headwind heading back to St. George. Plan your loop accordingly.
- If you’re looking ahead to Saturday: Sunny, 81°F on Staten Island — the warmest borough by 3–4°F, and the first beach-weather Saturday of the year. Saturday is the day.
