Heat wave coming to California, cool nights in central Mexico

Temperatures throughout California this week were a little cooler due to the wind and unstable air. Temperatures throughout the state, however, will be 10 degrees warmer tomorrow and Sunday compared to today’s high temps. The coastal growing regions of Salinas, Santa Maria and Oxnard will be in the low 70s this weekend, while the San Joaquin Valley will see high temps in the mid-80s and the desert regions in the low 90s.

By Monday the temps will drop down few degrees in all areas, but come Wednesday, April 17 the real heat wave begins and will last at least through Sunday, April 21. Expect the desert regions to see the upper 90s, the SJV to be in the low 90s and coastal regions to be in the upper 70s to low 80s.

Look for all regions to be in full production with their spring crops over the next 10 days.

Blueberries out of the Golden State have begun. Todd Sanders of the California Blueberry Commission said the harvest in the San Diego region has already started, while the big players in the San Joaquin Valley are just starting to scratch the bushes at the southern end of the valley around Bakersfield and should be up and running in the next 10 days. From there the harvest will move north through the valley and to the coastal regions.

He said the rain has been great for the bushes and the cold weather has provided an excellent number of chilling hours. “These factors have left the plants healthy and full of fruit. We will see a much larger crop than last year,” Sanders said. The only negative effect he mentioned is that the plants are about seven days behind schedule due to the cold.

The season should last about six week and will peak in late May. Look to promote blueberries for Memorial Day.

Georgia, according to the USDA National Shipping Point Trends report, has also begun light harvest of early varieties of blueberries.

Mexico shipped 45 loads of blueberries last week; however, the main growing regions of Michoacán are experiencing cool temps this week.

Florida is coming on strong doubling production every week since starting three weeks ago. Last week they shipped 29 loads. 

Central Mexico can expect some unusually cool nights for this time of year. Tonight and tomorrow certain regions of Michoacán, Puebla and Guanajuato can expect low temps down into the low 40s and some high 30s. These are temps eight to 12 degrees below normal. Last night through Saturday will be the coldest days of the snap, but things won’t get back to normal with min temps in the 50s until Friday of next week. Blueberries and avocados are coming from these regions of Michoacán. Wet veg coming from regions of Puebla and Guanajuato.

Sinaloa and Sonora are expecting normal temps for this time of year. Max temps are in the upper 80s to low 90s.

The states of Florida and Georgia can expect warm days with occasional afternoon thunderstorms over the next 10 days. The best chance of rain will come this Sunday and next Thursday and Friday. The higher rain totals will be in northern Florida and Georgia. The farther south you go down the Florida peninsula the less rain you will see. Northern Florida and Georgia can expect high temps in the low to mid-80s while southern Florida can expect max temps in the 90s. Check the Weathermelon app for specific locations.
