Central Park Nature Notes: Fri May 22 – Thu May 28

Hello nature lovers,

A quiet week on the permit calendar in the places that matter — neither the Conservancy nor the Bird Alliance booked the Ramble, North Woods, the Loch, or Hallett — which is the way we like it. The weather IS the program this week: a wet weekend pulls migrants down into the trees, Memorial Day showers refill the waterfalls, and Wednesday delivers the season’s first 85°F day.

Weather this week

Cool and showery from tonight through Memorial Day with rain all day Saturday, thunderstorms likely Sunday, then a Tuesday dry-out and an 85°F partly-sunny Wednesday. For us, that means fallout conditions Sat–Sun morning, full waterfalls Mon onward, and the first heat of late spring midweek — pace yourself in the canopy.

Fri May 22 — between fronts, drying pavers in the Garden

Cool and transitional, possible AM showers, no Conservancy or Bird Alliance programming. Shakespeare Garden between rain bands is the play — late tulips, iris coming on, fewer visitors than normal because of the forecast. If the rain is steady, Sarah Yuster: Outside Voices at the Arsenal Gallery is open 9 AM–5 PM (free, all week) — a good indoor stop that still keeps you in the park.

Sat May 23 — rain all day, fallout in the Ramble

This is the day that rewards getting up. Migrants flying north on Friday’s southerlies will be forced down by the steady rain — the Ramble, the Point, and the Maintenance Field can hold birds at eye level all morning. Pre-dawn through about 9 AM, before the rain really sets in, is the wet birder’s dream window we get maybe twice a spring. Pack the rain shell, the lens cloth, and a thermos. Skip the south end entirely — the Bandshell and Hernshead programming will run rain-or-shine.

Sun May 24 — thunderstorms likely, listen for the Loch

62°F with storms building through the afternoon. Morning is again the window — same fallout logic as Saturday, possibly with a few different birds dropped in overnight. Once the storms arrive, head home; lightning over the Reservoir is not the place to be. By Sunday evening, the Loch and the Cascade in the Ravine will be running full for the first time in weeks.

Mon May 25 — Memorial Day showers, waterfalls peak

Memorial Day, 74°F, scattered rain showers. With two soaking days behind us, this is the Ravine’s afternoon: the Loch waterfalls and the Glen Span / Huddlestone arches will be at full flow. Wet boots, but the soundtrack is worth it. The south end is loud with permits and skaters — stay north of 100th Street and you’ll have the Ravine essentially to yourself.

Tue May 26 — dry-out, 80°F, the canopy walks

The first dry day in five. Mostly cloudy, warm but not punishing, post-rain leaves still glossy. Hallett Nature Sanctuary mid-morning is wide open today — no programming, no permits, just the sanctuary at its lushest. Pair it with a Ramble loop and you’ve had the week’s best ecology walk. The Conservancy and Bird Alliance have nothing on the books in our zones all week, so this is your unguided window.

Wed May 27 — 85°F, first heat of late spring

The warmest day of the year so far. Get out before 8 AM — by midday the canopy is the only comfortable place. The Ramble holds 5–8°F cooler than the open lawns; the North Woods even more. One operational note: the J.P. Morgan Corporate Challenge runs the loop in the evening (roughly 6–9 PM, ~15K runners). Stay north of 86th Street after work and you won’t hear it — the Reservoir, Conservatory Garden, and the Loch are all clear of the noise.

Thu May 28 — First solid sun, post-rain bird activity, The Pond Lawn closed

80°F sunny — the first solid dry day with the migration pulse still settling. Birds are active in the Ramble and the Conservatory Garden after four wet days pushed them down into the canopy. The Pond Lawn is closed for maintenance all day — the Hallett area is still walkable but the lawn itself is fenced, so plan the south end accordingly. Central Park Conservancy Women’s Committee Game Event at Chess and Checkers, 8 AM is the Conservancy stop on the calendar. The Corporate Challenge wind-down keeps the south loop busy — another day to stay north of 86th for true solitude.

Wed 5/27 — 85°F, dawn or canopy only; stay north of 86th in the evening
