Orlando Weather Guide: Normals, Rainy Season and Storm Contacts

Orlando International Airport averages 51.45 inches of rain a year under the 1991 to 2020 normals, with July the hottest month at a normal high of 92.0 degrees and January the coolest at 71.8 (NOAA ACIS annual normals).

The official Orlando numbers come from the ORLANDO INTL AP station, which NOAA's Applied Climate Information System lists under the identifiers KMCO and MCO at an elevation of 89 feet (NOAA ACIS monthly normals). The normals on this page are that single airport station, not a reading taken at Lake Eola, downtown or Winter Park. ACIS documentation defines the normal code 91 used in these queries as the NCEI 1991 to 2020 normal (ACIS web services documentation).

At the Orlando airport the normal low climbs from 49.5 degrees in January to 73.7 in August, the warmest night of the year by normal, while the normal high runs from 71.8 in January to 92.0 in July (NOAA ACIS monthly normals). November is the driest month at 1.79 inches and June the wettest at 8.05.

The Orlando seasonal weather patterns guide walks through these months in more depth; this hub keeps the numbers in one place.

The median start of the Orlando wet season is May 27 and of the dry season Oct. 15, in the NWS Melbourne study that uses an Orlando period of record from 1950 to the present (NWS Melbourne wet and dry seasons).

NWS Melbourne lists 80 to 90 thunderstorm days for interior Orlando, against 70 to 80 on the east coast at Melbourne and Vero Beach and 90 to 100 on the west coast at Lakeland (NWS Melbourne lightning statistics). The airport normals show the switch clearly: May averages 4.02 inches of rain, then June jumps to 8.05 (NOAA ACIS monthly normals).

The same NWS Melbourne study dates the cool-down that follows. The median date of Orlando's first temperature below 60 degrees is October 19, and of the first below 50 is November 5 (NWS Melbourne wet and dry seasons). Nearby Sanford shares the Orlando dates for both the wet and dry season onsets.

Read together, the median dates put the dry season start (Oct. 15) and the first reading below 60 degrees (October 19) in the same week of October (NWS Melbourne wet and dry seasons).

A normal January night at Orlando International Airport drops to 49.5 degrees, while the lowest daily record in the NWS Melbourne Orlando January summary, whose records run from January 01, 1892 to the present, is 19 degrees on January 21, 1985 (NWS Melbourne January summary).

The January summary lists daily normal highs of 71 to 73 and lows of 49 to 50 through the whole month, with a monthly average of 60.6 degrees (NWS Melbourne January summary). The same page ranks the warmest January on record at an average of 71.6 degrees in 1974 and the coolest at 50.6 in 1977.

The January 1985 freeze set the record lows for January 21 and January 22 in the Orlando record, at 19 and 20 degrees, and the daily records for January 19 and 20, 1977 sit at 24 and 20 (NWS Melbourne January summary). The wettest January in the record is 8.54 inches in 1912, against a 2.48 inch normal (NWS Melbourne January summary).

Orange County Government lists the Atlantic hurricane season as June 1 through November 30 (Orange County Hurricane Safety Guide) and sends severe weather messages through its OCAlert system by text, email or phone (Orange County Emergency Information).

The county safety guide sets out four preparation steps: a family emergency communication plan, a disaster supply kit, knowledge of the local evacuation route and shelter locations, and protecting the home, with linked articles on sandbag use, tree trimming and generator safety (Orange County Hurricane Safety Guide). The Office of Emergency Management answers at 3-1-1 or 407-836-3111 (Orange County Emergency Information).

Orange County splits storm calls three ways. Dial 911 for life-threatening emergency assistance from the Orange County Sheriff's Office or Fire Rescue, 311 for non-emergency flooding, debris, downed trees, traffic matters and road conditions, and 211 for food, housing, financial assistance and crisis support (Orange County Who To Call).

One caution for anyone using the county page this fall: on October 18, 2026 the Orange County Emergency Information page still advertised a Hurricane Expo on June 21, 2025 at Evans High School and a Hurricane Milton SBA loan deadline of April 27, 2025 (Orange County Emergency Information). Both notices are more than a year old, so event dates there need checking against the county newsroom, which the county's Who To Call page links (Orange County Who To Call). The Orlando hurricane season guide covers inland tropical hazards in more detail.

Street flooding inside Orlando city limits goes to the city flooding hotline at 407.246.2238, and the city sends stormwater staff to inspect the flooding issue (City of Orlando Report Flooding).

The service covers flooded locations within city limits only and does not apply to flooding inside a home, and an emergency goes to 911. Reports can also be filed online, and the Streets and Stormwater Division is based at City Hall, 400 South Orange Avenue (City of Orlando Report Flooding). Addresses in unincorporated Orange County report non-emergency flooding to the county at 311 instead (Orange County Who To Call).

Sandbags come at announced distribution events. In July 2025 the City of Orlando Streets and Stormwater Division handed out free premade sandbags at 1010 Woods Avenue on July 10, 11 and 12, with staff loading vehicles, a self-serve option and a limit of 10 sandbags per vehicle (City of Orlando press release, July 2025). That release is the most recent city distribution notice found for this page, so the location and limit for a future storm should be confirmed when the city announces one.

The Orlando historical storm impacts guide covers what Charley, Irma, Ian and Milton did to the city and county.

June 2026 ranks as the fourth warmest June in the Orlando record at an average of 83.6 degrees, behind only 1998, 1903 and 1927, in the NWS Melbourne June summary (NWS Melbourne June summary).

The warm June sits alongside 2022, 2024 and 2019 in the same top ten, so four of the Junes on that top ten list, 2019, 2022, 2024 and 2026, date from 2019 on (NWS Melbourne June summary). The wettest June on the list remains 18.28 inches in 1968, and 2005 is second at 17.39 (NWS Melbourne June summary), against an 8.05 inch June normal at the airport (NOAA ACIS monthly normals).

January 2026 also shows up in the record: the January summary credits 2026 with the daily record highs for January 9, at 84 degrees, and January 25, at 87 (NWS Melbourne January summary).

Last verified: October 18, 2026, against the NWS Melbourne Orlando climate summaries and season studies, the NOAA ACIS normals for Orlando International Airport, and the Orange County and City of Orlando emergency pages.
