TODAY: Mostly clear skies and a breezy feel Tuesday — highs in the upper 70s, but northeast winds running 20 to 25 mph will make the air feel sharper than that number suggests. No rain chance. Winds ease to 15 to 20 mph by late afternoon, according to NWS Melbourne forecasters.

TONIGHT: Partly cloudy. Low in the upper 60s. East winds drop from 10 to 15 mph down to 5 to 10 mph after midnight — a noticeably calmer overnight than what Tuesday morning delivers.

THIS WEEK: Wednesday brings partly cloudy skies, upper-70s highs, and a more manageable east wind at 10 to 15 mph. Wednesday night turns cloudier — considerable cloud cover through Thursday, which holds the same upper-70s high and 10 to 15 mph east winds. No rain is indicated through Thursday, though the building clouds Wednesday night bear watching. No active pattern change is expected before the end of the NWS Melbourne forecast window.

ON THE WATER: Tuesday is rough on coastal and nearshore waters. Northeast winds at 20 to 25 mph will push wind waves and chop across the Indian River Lagoon and St. Lucie Estuary; expect steep short-period seas offshore. Captains planning inlet runs should wait for the afternoon wind decrease — conditions improve meaningfully after 3 p.m. By Wednesday, east winds at 10 to 15 mph make for far friendlier fishing, especially in the morning before the sea breeze reinforces. Anglers targeting snook along the beaches or pompano in the surf should treat Wednesday morning as the week's first quality opportunity.

ALERTS: No active NWS watches, warnings, or advisories are in effect for Martin, St. Lucie, or Indian River counties at this time, according to NWS Melbourne data.

The bottom line for Tuesday: it's a beautiful, rain-free spring day on the Treasure Coast — just hold your hat, leave the boat at the dock until afternoon, and know that calmer, nearly ideal conditions are only 24 hours away.
