Orlando residents can look forward to mild weather this weekend, but they should brace themselves for a dip in temperatures and breezier conditions with the onset of a cold front late Sunday into Monday. The National Weather Service Melbourne FL, in their latest Area Forecast Discussion, highlights the pleasant conditions with slightly above-normal temperatures expected before the change in weather dynamics. Those planning outdoor activities should make the most of the sunshine, though a light jacket might not go amiss in the mornings, especially north of Interstate 4.
Today, despite a slight chill in the morning air, temperatures across east-central Florida are expected to rebound into the 70s, with low 80s around Lake Okeechobee. By this afternoon, sunshine will help temperatures rebound into the 70s (low 80s around Lake Okeechobee), according to the report issued at 618 AM EST on December 20, 2025, describes. In the marine sector, favorable boating conditions are anticipated this weekend, with light onshore winds and seas forecasted to fall from 3-5 ft today to 2-4 ft by Sunday. However, deteriorating marine conditions are forecast behind Monday's cold front.
For the aviation sector, VFR conditions persist through the terminal aerodrome forecast period. Northerly wind, transitioning to a northeast direction, is anticipated to remain generally under 10 knots throughout the day. Things are looking a little different as we head into the week, with an early week cold front slated to bring about an uptick in rainfall chances, predominantly along coastal areas, starting Monday afternoon through Tuesday. Established onshore flow and an increase in low-level moisture should build at least a scattered marine stratocu field over the local Atlantic on Monday, per the Aviation discussion.
The weather outlook carries into the holiday week with mostly dry conditions and temperatures during the day ranging pleasantly from the mid-70s to near 80 degrees (south). Overnight lows are expected to settle into the upper 50s/mid 60s Monday night, but will fall into the 50s for most locations for the rest of the week. Seasonal revelers may also take note that H5 height anomalies are hinting at a warmer Christmas Day for the central and southern U.S. this year.
High pressure hovering over the waterways this weekend will provide favorable boating conditions with seas subsiding from 3-5 ft today to 2-4 ft by Sunday. However, mariners should stay alert as a front moving south across the waters will generate Northeast winds increasing to 15-24 kt (gusts up to 30 kt offshore) by Monday and Monday night. Winds slacken gradually on Tuesday, but mariners can expect poor to hazardous conditions to start the holiday week and linger through at least Tuesday morning, according to forecasts National Weather Service. Improvements in marine conditions are expected mid to late week as surface high pressure reasserts its presence.
